C) Incorrect: Assessing the client's vital signs is essential, but it is not the first action to be taken. Verifying the client's identity and blood type is the priority before starting the transfusion.
D) Incorrect: Obtaining informed consent from the client is crucial but not the first action to be taken. The nurse should first verify the client's identity and blood type before seeking consent for the transfusion.
Explanation
A) Incorrect: A slight increase in blood pressure is not a significant vital sign alteration that requires immediate reporting before initiating the transfusion. It could be related to various factors, such as anxiety or pain.
B) Incorrect: A respiratory rate of 22 breaths per minute is within the normal range for an adult and does not require immediate reporting before starting the transfusion.
C) Incorrect: A decrease in heart rate from 88 to 72 beats per minute is not a critical vital sign alteration. As long as the heart rate remains within the client's baseline range, it does not need immediate reporting.
D) Correct: An elevated temperature of 38.5°C (101.3°F) may indicate a fever, which could be a sign of an infection or an adverse reaction to the transfusion. The nurse should report this vital sign alteration to the healthcare provider before proceeding with the transfusion to determine the appropriate course of action.
Explanation
A) Incorrect: Warming the blood product in a microwave oven is not an appropriate action and could lead to hemolysis of the blood components. Blood should be warmed using an approved blood warmer designed for this purpose.
B) Incorrect: Administering a discolored blood product or one containing clots is unsafe and could cause harm to the client. The nurse should not proceed with the administration and should take appropriate actions.
C) Correct: If the nurse discovers that the blood product is discolored or contains clots, the nurse should discard the blood product appropriately and notify the blood bank immediately. This will ensure that the client receives a safe and suitable blood product for the transfusion.
D) Incorrect: Filtering the blood product through a standard IV filter is not sufficient to remove any clots present in the blood product. Using a blood product that appears abnormal could lead to adverse reactions in the client, so it is essential to obtain a replacement from the blood bank.
Explanation
A) Incorrect: Iron-deficiency anemia is not a contraindication for a blood transfusion. In fact, it is one of the common indications for transfusion in clients with severe anemia.
B) Incorrect: Chronic kidney disease is not a contraindication for a blood transfusion. Transfusions may be necessary for clients with chronic kidney disease who develop anemia due to decreased erythropoietin production.
C) Correct: Hemolytic anemia is a contraindication for a blood transfusion. This condition involves the destruction of red blood cells, and a transfusion with incompatible blood can worsen the hemolysis and lead to a severe transfusion reaction.
D) Incorrect: Hypertension is not a contraindication for a blood transfusion. While the nurse should monitor blood pressure during the transfusion, hypertension alone does not preclude the need for a transfusion in a client with other indications for blood products.
A client expresses anxiety and fear about receiving a blood transfusion. What action should the nurse take to address the client's concerns?
Explanation
A) Incorrect: While explaining the blood transfusion procedure is essential, doing so in excessive detail may increase the client's anxiety. The nurse should provide information in a clear and concise manner, addressing the client's specific concerns.
B) Incorrect: Offering a warm blanket is a comfort measure but may not be sufficient to address the client's anxiety and fear about the transfusion. The nurse should engage in therapeutic communication and provide emotional support.
C) Incorrect: Requesting a sedative for the client may not be the best course of action unless specifically prescribed by the healthcare provider. It is essential to explore other interventions to address the client's anxiety before resorting to medication.
D) Correct: Providing the client with information about the benefits and risks of the transfusion can help alleviate their anxiety and fear. The nurse should engage in patient education, discuss the purpose of the transfusion, potential benefits, and possible risks involved. This empowers the client with knowledge and helps them make informed decisions.

B) Correct. Performing CPR on someone who is not in cardiac arrest can cause harm and is not indicated. It is crucial to ensure the person is unresponsive and not breathing before initiating CPR.
C) Incorrect. Bystanders can play a vital role in initiating CPR in cardiac arrest situations. CPR training is not limited to healthcare professionals.
D) Incorrect. In cardiac arrest situations, time is of the essence. Waiting for emergency medical services to arrive without initiating CPR can significantly reduce the chances of survival for the individual experiencing cardiac arrest.
Explanation
A) Incorrect. While medications are important in advanced cardiac life support, the primary goal of early recognition and response is not the immediate administration of medications.
B) Incorrect. While transporting the client to a specialized cardiac care facility is necessary for some patients, it is not the primary goal of early recognition and response.
C) Incorrect. Advanced airway management and oxygen support are important in the resuscitation process, but the primary goal at the early stage is not advanced airway management.
D) Correct. The primary goal of early recognition and response in cardiac arrest situations is to start immediate chest compressions and deliver rescue breaths to support circulation and oxygenation. These interventions are essential to maintaining blood flow and oxygen delivery to vital organs until advanced medical support is available.
Questions
Explanation
A) Incorrect. Compressing the chest to a depth of 1 inch (2.5 cm) is too shallow for effective adult CPR. Deeper compressions are required.
B) Correct. The recommended compression depth for adult CPR is 2 inches (5 cm). This depth allows for sufficient blood flow to vital organs and is consistent with current CPR guidelines.
C) Incorrect. Compressing the chest to a depth of 3 inches (7.5 cm) is deeper than necessary for adult CPR. Excessive compression depth may cause harm.
D) Incorrect. Compressing the chest to a depth of 4 inches (10 cm) is much deeper than the recommended depth for adult CPR. Excessive depth can lead to rib fractures and other injuries.
Explanation
A) Incorrect. For children in cardiac arrest, the standard CPR technique involves both chest compressions and rescue breaths. Hands-Only CPR is most appropriate for adults in cardiac arrest.
B) Incorrect. Near-drowning incidents may involve respiratory issues and potential water aspiration, making the delivery of rescue breaths essential. Hands-Only CPR is not the most appropriate technique in this situation.
C) Correct. Hands-Only CPR is most appropriate when the client is unresponsive and not breathing after sudden cardiac arrest, especially in adult victims. In such cases, bystanders can provide continuous chest compressions until professional help arrives.
D) Incorrect. For severe allergic reactions, the primary intervention is to administer epinephrine and seek emergency medical assistance. Hands-Only CPR is not indicated for anaphylactic reactions.
Explanation
A) Incorrect. Placing the hands on the lower half of the breastbone is not the correct hand placement for adult CPR chest compressions. The hands should be positioned higher on the sternum.
B) Incorrect. Placing one hand on the chest and the other on the forehead is not the correct hand placement for adult CPR. Both hands should be positioned on the sternum.
C) Incorrect. Placing the hands on the upper abdomen is not the correct hand placement for adult CPR. The hands should be positioned on the sternum.
D) Correct. The correct hand placement for adult CPR chest compressions is to center the hands on the sternum, between the nipples. Proper hand placement ensures effective compression depth and allows for adequate blood flow during CPR.
Explanation
A) Incorrect. The compression-to-ventilation ratio of 5:1 is not the current guideline for adult CPR. The correct ratio involves more frequent compressions.
B) Correct. The recommended compression-to-ventilation ratio for adult CPR is 30:2. This means 30 chest compressions followed by 2 rescue breaths.
C) Incorrect. The compression-to-ventilation ratio of 15:2 is not the current guideline for adult CPR. The correct ratio involves more frequent compressions, as mentioned in option B.
D) Incorrect. The compression-to-ventilation ratio of 10:1 is not the current guideline for adult CPR. The correct ratio involves more frequent compressions and periodic rescue breaths, as mentioned in option B.
Explanation
A) Incorrect. While emotional comfort is important, high-quality CPR is not primarily aimed at ensuring the client's emotional comfort during resuscitation efforts.
B) Incorrect. High-quality CPR focuses on providing effective chest compressions and ventilations to the client, rather than conserving the energy of healthcare providers.
C) Incorrect. High-quality CPR emphasizes proper technique and compression depth to minimize the risk of injury to both the client and the healthcare provider.
D) Correct. High-quality CPR is critical because it improves the likelihood of restoring blood circulation and oxygenation to vital organs during resuscitation efforts. Effective chest compressions maintain blood flow, while rescue breaths provide oxygen to the lungs, enhancing the chances of a successful resuscitation outcome.
Questions
Explanation
A) Correct. The first step when using an AED is to turn on the device and check for responsiveness. Ensuring the AED is powered on and ready for use is critical before starting any other steps.
B) Incorrect. After turning on the AED, the provider should place the pads on the victim's chest and connect the AED. However, this is not the first step in the process.
C) Incorrect. After connecting the AED to the victim, the device will automatically analyze the victim's heart rhythm to determine if a shock is needed. However, analyzing the rhythm is not the first step.
D) Incorrect. Performing a quick physical examination is not the first step when using an AED. The immediate priority is to check for responsiveness and turn on the AED.
Explanation
A) Incorrect. An AED is not used to relieve pain and discomfort during cardiac arrest. Its primary purpose is to restore a normal heart rhythm.
B) Correct. The primary purpose of an AED is to restart the heart and restore a normal heart rhythm during cardiac arrest. It delivers a controlled electric shock to the heart to stop abnormal rhythms and allow the heart's natural pacemaker to regain control.
C) Incorrect. While medications may be used in advanced cardiac life support, an AED is not designed to administer medications. Its focus is on delivering defibrillation shocks.
D) Incorrect. While an AED may have basic monitoring capabilities, its primary purpose is not to monitor vital signs during resuscitation efforts. The AED is used for defibrillation to treat cardiac arrest.
Explanation
A) Incorrect. Placing the pads on the right side of the chest is not the correct position for defibrillation. The pads should be positioned differently.
B) Correct. The proper placement of AED pads involves placing one pad on the center of the chest and the other pad on the left side of the chest. This placement allows the electrical current to flow effectively through the heart and is consistent with current guidelines.
C) Incorrect. Placing one pad on the back and the other on the front of the chest is not the recommended position for AED pads. The pads should be placed on the chest.
D) Incorrect. Placing the pads on the lower abdomen is not the correct position for defibrillation. The pads should be positioned on the chest to deliver the electric shock to the heart.
Explanation
A) Correct. Ensuring that the AED is turned on before placing the pads on the victim's chest is a safety measure. This ensures the AED is ready for use and can begin the analysis process immediately.
B) Incorrect. While it is essential to stand clear and avoid touching the victim during defibrillation, this is not the response to the client's question about general safety measures.
C) Incorrect. It is crucial to stand clear and avoid touching the victim while the AED is analyzing and delivering a shock. Performing CPR during defibrillation can interfere with the accuracy of the analysis and the delivery of the shock.
D) Incorrect. The AED is specifically designed for use during cardiac arrest when the victim is unresponsive and not conscious. Using the AED is not appropriate for conscious individuals who can follow instructions.
Questions
Explanation
A) Incorrect. While providing regular breaks for team members is important, it is not the primary purpose of closed-loop communication during CPR.
B) Correct. The primary purpose of closed-loop communication in a CPR team is to ensure that team members understand their roles and responsibilities clearly. It involves repeating back and confirming instructions to promote effective teamwork and prevent errors.
C) Incorrect. Closed-loop communication primarily focuses on intra-team communication to coordinate resuscitation efforts efficiently. Informing bystanders is important, but it is not the primary purpose of closed-loop communication.
D) Incorrect. Reporting resuscitation outcomes to the hospital administration is not the primary purpose of closed-loop communication during CPR. Its focus is on effective communication within the resuscitation team.
Explanation
A) Incorrect. While the team leader plays a crucial role in providing direction, making all decisions independently can hinder effective team dynamics. Collaboration and input from team members are essential for optimal outcomes.
B) Incorrect. While delegation is important, expecting the team leader to delegate all tasks without involvement from other team members does not promote effective team dynamics. Communication and coordination are essential.
C) Correct. Encouraging open communication and input from all team members fosters effective team dynamics during CPR. Each team member brings valuable insights and skills to contribute to the resuscitation efforts.
D) Incorrect. While maintaining a calm demeanor is important, the team leader should involve other team members in decision-making and communication. Effective team dynamics rely on collaborative efforts.
Explanation
A) Incorrect. While verbal communication is crucial during CPR, relying solely on verbal communication may not be sufficient for accurate information exchange, especially in high-stress situations.
B) Correct. CPR teams use both verbal and written communication for a comprehensive understanding of the resuscitation plan. Verbal communication allows for real-time updates, while written communication, such as documentation and checklists, helps ensure critical information is conveyed and understood.
C) Incorrect. Hand signals and nonverbal cues can be valuable additions to communication during CPR, especially in noisy environments or when verbal communication is challenging.
D) Incorrect. While electronic devices can be used for communication, they may not be practical or necessary during CPR. Verbal and written communication are the primary modes of communication in such situations.
Explanation
A) Incorrect. While task assignment is an essential aspect of leadership, this example does not demonstrate closed-loop communication, which involves feedback and confirmation from the team member.
B) Correct. In closed-loop communication, the team leader gives instructions, and the team member provides confirmation once the task is completed. This process ensures clear communication and understanding between the team leader and team member.
C) Incorrect. Closed-loop communication involves two-way communication with feedback. In this example, the team leader is not seeking input or feedback from team members.
D) Incorrect. Closed-loop communication involves active engagement and acknowledgment between the team leader and team members. In this example, the team leader expects acknowledgment or response from team members.
Questions
Leukemia
A client asks the nurse, "What is leukemia?" How should the nurse respond?
Explanation
A) This choice is incorrect because leukemia does not primarily affect the lymph nodes. It is a cancer of the blood and bone marrow, where abnormal white blood cells are produced.
B) This choice is incorrect because leukemia is not characterized by the overproduction of platelets. Platelets are involved in blood clotting, and their overproduction is not a feature of leukemia.
C) This choice is correct. Leukemia is a type of cancer characterized by the uncontrolled proliferation of abnormal white blood cells in the bone marrow. These abnormal cells then enter the bloodstream, crowding out healthy blood cells and impairing normal blood cell function.
D) This choice is incorrect because leukemia is not an autoimmune disorder. It is a cancerous condition involving abnormal white blood cell growth.
Explanation
A) This choice is incorrect because chronic leukemia can affect both children and adults, not just children and young adults.
B) This choice is incorrect because chronic leukemia progresses more slowly than acute leukemia and does not typically require immediate treatment.
C) This choice is correct. Chronic leukemia is characterized by the overproduction of mature and functional white blood cells. Unlike acute leukemia, the abnormal cells in chronic leukemia are more developed and functional, but they may not function correctly, leading to an accumulation of these cells in the blood.
D) This choice is incorrect because chronic leukemia usually presents with milder symptoms compared to acute leukemia. Hospitalization is not typically required unless complications arise.
Explanation
A) This choice is incorrect because leukemia is not always caused by inherited genetic mutations. While genetic factors can contribute to the development of some types of leukemia, it is not the only cause.
B) This choice is incorrect because there are known genetic links to certain types of leukemia. For example, some forms of leukemia, such as chronic myeloid leukemia (CML), are associated with specific genetic mutations.
C) This choice is incorrect because genetic factors and environmental factors can both play a role in the development of leukemia. Some cases may be influenced more by genetic factors, while others may be influenced more by environmental factors.
D) This choice is correct. Leukemia can have various causes, including genetic mutations, exposure to certain environmental factors (e.g., radiation, certain chemicals), and viral infections. While some cases may have a genetic basis, others may be triggered by environmental factors or have an unknown cause.
Explanation
A) This choice is incorrect because leukemia is not a contagious disease. It cannot spread from person to person through direct contact.
B) This choice is correct. Leukemia is not contagious. It is a type of cancer caused by abnormal white blood cells in the bone marrow and blood. It cannot be transmitted from one person to another.
C) This choice is incorrect because leukemia is not contagious, even if the person has a weakened immune system. It is not a communicable disease.
D) This choice is incorrect because leukemia is not transmitted through blood transfusions. Blood transfusions involve screened and tested blood products, and leukemia cannot be passed on through this process.
Explanation
A) This choice is incorrect because unexplained weight gain is not a common symptom of leukemia. Weight loss may be more typical in some cases.
B) This choice is correct. Easy bruising and bleeding are common manifestations of leukemia due to a decreased number of healthy blood cells and platelets, which are responsible for clotting.
C) This choice is correct. Persistent fatigue and weakness are common symptoms of leukemia. Leukemia can lead to a decrease in normal blood cells, causing anemia and leading to fatigue and weakness.
D) This choice is correct. Leukemia can weaken the immune system, making the person more susceptible to infections, leading to frequent infections and fever.
E) This choice is correct. Leukemia can cause the enlargement of lymph nodes, leading to painful and swollen lymph nodes.
Explanation
A) This choice is incorrect because while a complete blood count (CBC) is an important initial screening test for leukemia, it alone is not definitive for diagnosis. A CBC may show abnormal levels of blood cells, prompting further investigation, including a bone marrow biopsy.
B) This choice is incorrect because a urinalysis is not used to diagnose leukemia. It is a test used to evaluate kidney function and detect urinary abnormalities.
C) This choice is incorrect because a chest X-ray is not a definitive diagnostic tool for leukemia. It is primarily used to assess the lungs and chest organs for conditions such as pneumonia or tumors.
D) This choice is correct. A bone marrow biopsy is a definitive diagnostic tool to confirm leukemia. In this procedure, a small sample of bone marrow is taken from the hipbone or breastbone and examined under a microscope to determine if leukemia cells are present. It allows for the identification of abnormal cells in the bone marrow, helping to establish the diagnosis and type of leukemia.
A nurse is providing care for a client undergoing treatment for leukemia. The client develops neutropenia. What is the nurse's priority intervention?
Explanation
A) This choice is incorrect because administering pain medication for bone pain is important for the client's comfort, but it is not the priority in this situation. Neutropenia is characterized by a low neutrophil count, which can lead to an increased risk of infection.
B) This choice is incorrect because while monitoring for signs of bleeding or bruising is essential for a client with thrombocytopenia (low platelet count), it is not the priority in this scenario. Neutropenia increases the risk of infection, which is the primary concern.
C) This choice is correct. Implementing strict isolation precautions is the priority for a client with neutropenia. Neutropenia results in a decreased ability to fight off infections, so measures to prevent exposure to potential pathogens are crucial in reducing the risk of infection.
D) This choice is incorrect because avoiding invasive procedures and injections is a precaution for clients with thrombocytopenia, not specifically neutropenia. While both conditions involve low blood cell counts, the risk of infection is the primary concern in neutropenia.

B) This choice is incorrect because leukemia is not characterized by the overproduction of platelets. Platelets are involved in blood clotting, and their overproduction is not a feature of leukemia.
C) This choice is correct. Leukemia is a type of cancer characterized by the uncontrolled proliferation of abnormal white blood cells in the bone marrow. These abnormal cells then enter the bloodstream, crowding out healthy blood cells and impairing normal blood cell function.
D) This choice is incorrect because leukemia is not an autoimmune disorder. It is a cancerous condition involving abnormal white blood cell growth.
Explanation
A) This choice is incorrect because leukemia is not limited to just one type. There are different subtypes of leukemia, including acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML), among others.
B) This choice is correct. Leukemia can be broadly classified into two main types: acute leukemia, which progresses rapidly and requires immediate treatment, and chronic leukemia, which progresses more slowly.
C) This choice is incorrect because the classification of leukemia is not solely based on age. Leukemia can occur in both children and adults.
D) This choice is incorrect because the classification of leukemia does not involve solid tumors. Leukemia is a cancer of the blood and bone marrow, characterized by the uncontrolled growth of abnormal white blood cells.
Explanation
A) This choice is incorrect because acute leukemia is characterized by a rapid onset and fast progression of symptoms. It requires immediate treatment due to its aggressive nature.
B) This choice is correct. Acute leukemia is characterized by the uncontrolled and rapid proliferation of abnormal white blood cells in the bone marrow, which leads to a high accumulation of these immature cells in the bloodstream.
C) This choice is incorrect because, in general, acute leukemia has a lower survival rate compared to chronic leukemia. Acute leukemia requires immediate and aggressive treatment, and the prognosis depends on various factors, including the subtype and individual response to therapy.
D) This choice is incorrect because acute leukemia is not indolent or slow-growing. It progresses rapidly and can have a significant impact on blood cell counts and overall health.
Explanation
A) This choice is incorrect because chronic leukemia can affect both children and adults, not just children and young adults.
B) This choice is incorrect because chronic leukemia progresses more slowly than acute leukemia and does not typically require immediate treatment.
C) This choice is correct. Chronic leukemia is characterized by the overproduction of mature and functional white blood cells. Unlike acute leukemia, the abnormal cells in chronic leukemia are more developed and functional, but they may not function correctly, leading to an accumulation of these cells in the blood.
D) This choice is incorrect because chronic leukemia usually presents with milder symptoms compared to acute leukemia. Hospitalization is not typically required unless complications arise.
Explanation
A) This choice is incorrect because a bone marrow biopsy is not performed to remove a tumor mass. The purpose of the procedure is to obtain a sample of bone marrow tissue for diagnostic evaluation.
B) This choice is incorrect because assessing the presence of circulating cancer cells in the bloodstream is typically done through a blood test, not a bone marrow biopsy. The biopsy provides direct information about the condition of the bone marrow.
C) This choice is incorrect because evaluating the overall blood cell count and differential is typically done through a complete blood count (CBC) test, not a bone marrow biopsy. The biopsy provides more detailed information about the bone marrow and its cellular composition.
D) This choice is correct. The primary purpose of a bone marrow biopsy is to obtain a sample of bone marrow tissue for examination under a microscope. This allows healthcare professionals to assess the presence of abnormal cells, determine the type and extent of leukemia, and guide treatment decisions.
Explanation
A) This choice is incorrect because stem cell transplantation is not the primary treatment for all cases of chronic myeloid leukemia (CML). It may be considered in certain cases, but targeted therapy is the standard first-line treatment for most patients with CML.
B) This choice is incorrect because while chemotherapy and radiation therapy are used in some leukemia treatments, they are not the main treatments for CML. Targeted therapy with tyrosine kinase inhibitors is the standard approach for CML management.
C) This choice is correct. The mainstay of treatment for chronic myeloid leukemia (CML) is targeted therapy with tyrosine kinase inhibitors (TKIs). TKIs are oral medications that specifically target the abnormal protein produced by the BCR-ABL gene, which drives the overproduction of white blood cells in CML. These medications are highly effective and have revolutionized the treatment of CML, leading to improved outcomes for many patients.
D) This choice is incorrect because watchful waiting and supportive care may be considered for certain low-risk or asymptomatic cases of CML, but it is not the primary treatment approach. Targeted therapy with TKIs is the standard treatment for most patients with CML.
Explanation
A) This choice is incorrect because chemotherapy for acute lymphocytic leukemia (ALL) usually lasts much longer than a few weeks. ALL treatment consists of several phases, and the overall duration can extend over several years.
B) This choice is correct. Treatment for acute lymphocytic leukemia (ALL) typically involves multiple phases, including induction, consolidation, and maintenance therapy. The induction phase aims to achieve remission, the consolidation phase aims to eliminate any remaining cancer cells, and the maintenance phase aims to prevent relapse and keep the leukemia in remission. Overall, the treatment can extend over several years, depending on the client's response to therapy and risk factors.
C) This choice is incorrect because it does not accurately reflect the standard treatment approach for ALL. Clients with ALL do not typically switch from chemotherapy to radiation therapy after a few days.
D) This choice is incorrect because ALL treatment typically involves multiple rounds of chemotherapy, not just a single round. The goal is to achieve long-term remission and prevent relapse, which requires a more comprehensive treatment approach over an extended period.
Questions
Explanation
A) This choice is incorrect because a family history of diabetes is not a known risk factor for leukemia. While genetics can play a role in some leukemia cases, diabetes is not associated with leukemia development.
B) This choice is incorrect because exposure to asbestos is a risk factor for certain types of cancer, such as lung cancer and mesothelioma, but it is not a primary risk factor for leukemia.
C) This choice is incorrect because while autoimmune disorders can affect the immune system, they are not a known risk factor for leukemia.
D) This choice is correct. A previous diagnosis of lymphoma is a significant risk factor for developing leukemia. Lymphoma and leukemia are both types of blood cancers, and individuals with a history of lymphoma have an increased risk of developing leukemia.
Explanation
A) This choice is incorrect because there is no strong evidence to support smoking as a major risk factor for leukemia. Smoking is primarily associated with lung cancer and other respiratory conditions.
B) This choice is incorrect because while smoking is associated with other types of cancer, such as lung, throat, and mouth cancers, it is not definitively linked to leukemia.
C) This choice is incorrect because while smoking can increase the risk of certain cancers, its link to leukemia remains uncertain. Research on this topic has not provided conclusive evidence of a significant association between smoking and leukemia development.
D) This choice is correct. The link between smoking and leukemia is still uncertain and not well-established. While smoking is a known risk factor for several types of cancer, its specific role in leukemia development requires further study.
Explanation
A) This choice is incorrect because a history of frequent dental cavities is not a known risk factor for leukemia.
B) This choice is incorrect because allergies to pollen and pet dander are not associated with an increased risk of leukemia.
C) This choice is incorrect because recurrent urinary tract infections are not known to be a risk factor for leukemia.
D) This choice is correct. Previous treatment with chemotherapy and radiation is a significant risk factor for developing leukemia. Certain chemotherapeutic agents and radiation therapy can damage healthy blood-forming cells in the bone marrow, potentially leading to the development of leukemia later on. This type of leukemia is often referred to as secondary or treatment-related leukemia.
Explanation
A) This choice is incorrect because a sedentary lifestyle is not a known risk factor for leukemia. Physical inactivity is associated with other health conditions but not leukemia.
B) This choice is incorrect because having a vegetarian diet is not a risk factor for developing leukemia.

Explanation
A) This statement is correct. Having a family history of leukemia is considered a risk factor for developing the disease, particularly in cases of familial or hereditary leukemia.
B) This statement is correct. Exposure to high levels of ionizing radiation, such as during radiation therapy or nuclear accidents, is a well-known risk factor for leukemia.
C) This statement is correct. Individuals with Down syndrome have an increased risk of developing leukemia, particularly acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML).
D) This statement is incorrect. While physical activity is beneficial for overall health and may reduce the risk of various cancers, there is no evidence to suggest that being physically active specifically reduces the risk of developing leukemia.
Explanation
A) This choice is incorrect because exposure to benzene is indeed a known risk factor for developing leukemia. Benzene is a chemical compound found in certain industrial settings and can increase the risk of developing leukemia, particularly acute myeloid leukemia (AML).
B) This choice is correct. Exposure to benzene is associated with an increased risk of leukemia. Benzene is a known carcinogen and can cause damage to blood-forming cells in the bone marrow, leading to the development of leukemia in some individuals.
C) This choice is incorrect because while benzene exposure is associated with an increased risk of leukemia, it is not primarily linked to skin cancer.
D) This choice is incorrect because benzene exposure can affect individuals of all ages, not just children. It is a risk factor for leukemia development in adults as well as children.
Questions
Explanation
A) This choice is incorrect because leukemia does not result from an overproduction of platelets. Leukemia involves an overproduction of abnormal white blood cells.
B) This choice is incorrect because leukemia is not caused by the body's immune system attacking healthy white blood cells. Instead, it involves the uncontrolled growth of abnormal white blood cells.
C) This choice is correct. Leukemia is characterized by genetic mutations in the bone marrow cells, particularly in the stem cells that produce white blood cells. These mutations lead to uncontrolled growth and proliferation of abnormal white blood cells, interfering with the normal production of other blood cells.
D) This choice is incorrect because an imbalance of red blood cells would not trigger the overproduction of white blood cells. Leukemia is specifically a disorder of white blood cell proliferation.
Explanation
A) This choice is incorrect because AML is not characterized by the overproduction of immature lymphocytes. It involves the uncontrolled proliferation of abnormal myeloid cells in the bone marrow.
B) This choice is incorrect because AML does not cause abnormal proliferation of red blood cells. Anemia may occur as a result of AML due to the displacement of normal blood-forming cells in the bone marrow.
C) This choice is correct. AML is a type of leukemia that arises from genetic mutations in the myeloid stem cells. These mutations lead to uncontrolled growth and accumulation of abnormal myeloid cells, including granulocytes, monocytes, and platelets.
D) This choice is incorrect because the abnormal growth of plasma cells leading to the production of abnormal antibodies is characteristic of multiple myeloma, not AML.
Explanation
A) This choice is incorrect because CLL specifically involves the overproduction of abnormal lymphocytes, not myeloid cells. Myeloid cells are affected in other types of leukemia, such as AML.
B) This choice is incorrect because CLL is a chronic and indolent type of leukemia. It has a slow onset and progresses slowly over time, unlike some other leukemias that may have a more rapid course.
C) This choice is correct. In CLL, abnormal lymphocytes, mainly B-lymphocytes, accumulate in the bone marrow and interfere with the production of other blood cells, including red blood cells, platelets, and other white blood cells.
D) This choice is incorrect because CLL does not involve a genetic mutation leading to uncontrolled growth of red blood cells. That description is more characteristic of polycythemia vera, a different type of blood disorder.
Explanation
A) This choice is incorrect because ALL does not result in the overproduction of red blood cells. It primarily affects lymphocytes, not red blood cells.
B) This choice is incorrect because ALL involves the overproduction of abnormal lymphocytes, not normal white blood cells. These abnormal lymphocytes crowd out normal cells.
C) This choice is correct. In ALL, the uncontrolled proliferation of abnormal lymphocytes leads to the overcrowding of the bone marrow. As a result, normal bone marrow cells, including red blood cells, platelets, and other white blood cells, are suppressed, leading to various cytopenias.
D) This choice is incorrect because ALL does not cause the bone marrow to become fibrous and unable to produce any blood cells. That description is more characteristic of myelofibrosis, a different bone marrow disorder.
Explanation
A) This choice is incorrect because leukemia arises from the uncontrolled growth and division of abnormal blood cells, not normal blood cells. These abnormal cells disrupt the normal functioning of the blood and bone marrow.
B) This choice is incorrect because while cancerous cells may infiltrate and replace healthy tissues in other types of cancer, leukemia primarily affects the bone marrow and blood, not other organs like the liver and lungs.
C) This choice is incorrect because while leukemia does involve genetic mutations, the formation of abnormal blood cells primarily occurs within the bone marrow, not in the lymph nodes.
D) This choice is correct. The pathophysiology of leukemia involves the abnormal proliferation and differentiation of bone marrow stem cells. These cells undergo genetic mutations, leading to the development of leukemia and the production of abnormal blood cells.
Explanation
A) This choice is incorrect because leukemia does not lead to the increased production of normal red blood cells. Instead, it causes the overproduction of abnormal white blood cells.
B) This choice is incorrect because leukemia does not lead to the accumulation of normal platelets in the blood. Thrombocytopenia, or low platelet count, is common in leukemia due to the suppression of normal platelet production in the bone marrow.
C) This choice is correct. In leukemia, the proliferation of abnormal white blood cells crowds out and suppresses the normal bone marrow stem cells responsible for producing red blood cells, platelets, and other white blood cells. This suppression leads to anemia and thrombocytopenia.
D) This choice is incorrect because while cancerous cells may infiltrate healthy tissues in other types of cancer, leukemia primarily affects the bone marrow and blood, not other organs or tissues.
Explanation
A) This choice is incorrect because the lymphatic system does not filter and remove abnormal blood cells in leukemia. The role of the lymphatic system is primarily related to the circulation of lymph fluid and the immune response, not the removal of abnormal blood cells.
B) This choice is incorrect because the lymphatic system is not responsible for producing and releasing abnormal white blood cells in leukemia. Leukemia originates from the bone marrow, not the lymphatic system.
C) This choice is correct. Leukemia is primarily a disorder of the bone marrow and blood. It does not directly involve the lymphatic system, which is responsible for carrying lymph fluid and supporting the body's immune function.
D) This choice is incorrect because while cancerous cells may infiltrate other organs and tissues in other types of cancer, leukemia primarily affects the bone marrow and blood, not the lymphatic system.
Questions
Explanation
A) This choice is incorrect because fatigue and weakness are common symptoms in leukemia, but they are not specific enough to confirm the diagnosis on their own.
B) This choice is correct. Night sweats and fever are classic symptoms of leukemia, especially in cases of acute leukemia. These symptoms are related to the presence of abnormal white blood cells in the bloodstream and their impact on the body's immune response.
C) This choice is incorrect because unexplained weight gain is not a typical symptom of leukemia. Weight loss is more commonly associated with this condition due to decreased appetite and increased energy expenditure.
D) This choice is incorrect because persistent headaches are not specific to leukemia and may indicate other underlying health issues.
Explanation
A) This choice is incorrect because swollen lymph nodes are more characteristic of chronic leukemia, not acute leukemia like AML.
B) This choice is correct. Chronic lymphocytic leukemia (CLL) is commonly associated with enlarged lymph nodes due to the accumulation of abnormal lymphocytes in these areas. It is a slow-progressing leukemia and often presents with lymphadenopathy.
C) This choice is incorrect because while ALL may involve enlarged lymph nodes, it is more commonly associated with symptoms like fatigue, bleeding, and bone pain.
D) This choice is incorrect because while CML may present with enlarged spleen and liver, it is less likely to cause significant lymphadenopathy compared to CLL.
Explanation
A) This choice is incorrect because increased platelet production would not lead to easy bruising and petechiae. It would, in fact, improve clotting abilities.
B) This choice is incorrect because overproduction of red blood cells would not directly cause easy bruising and petechiae. It may lead to symptoms like fatigue and pallor.
C) This choice is correct. Easy bruising and petechiae are common in leukemia due to a deficiency of platelets and impaired clotting factors in the blood. Leukemia can lead to decreased platelet production and clotting abnormalities, resulting in easy bleeding and bruising.
D) This choice is incorrect because a deficiency of white blood cells would not directly cause easy bruising and petechiae. It might lead to an increased risk of infections.
Explanation
A) This choice is incorrect because bone marrow suppression would lead to decreased production of blood cells but may not directly cause bone pain and tenderness.
B) This choice is incorrect because excessive calcium levels in the blood would not be a common cause of bone pain and tenderness in leukemia.
C) This choice is incorrect because rapid growth of bone tissue would not be a typical cause of bone pain and tenderness in leukemia.
D) This choice is correct. Bone pain and tenderness in leukemia are often caused by the accumulation of leukemic cells in the bones. These abnormal cells infiltrate the bone marrow and bone tissue, leading to pain and tenderness.
Explanation
A) This choice is incorrect because red blood cells are not directly involved in the body's immune response. Decreased red blood cells may cause anemia, but they are not responsible for frequent infections and recurrent fevers.
B) This choice is incorrect because platelets are involved in clotting and do not directly impact the body's immune response.
C) This choice is correct. Neutrophils are a type of white blood cell responsible for fighting infections. In leukemia, particularly when neutrophils are affected, the body's ability to fight infections becomes compromised, leading to frequent infections and recurrent fevers.
D) This choice is incorrect because lymphocytes, specifically B-lymphocytes, are affected in chronic lymphocytic leukemia (CLL). While CLL can lead to increased susceptibility to infections, neutrophil dysfunction is more commonly associated with recurrent infections in leukemia.
Explanation
A) This choice is incorrect because impaired bone density would not directly cause ecchymoses on the skin. It might lead to an increased risk of fractures, but not bruising.
B) This choice is correct. Ecchymoses (bruises) of varying sizes with minimal trauma are common in leukemia due to a deficiency of platelets and impaired clotting factors in the blood. Leukemia can lead to decreased platelet production and clotting abnormalities, resulting in easy bleeding and bruising.
C) This choice is incorrect because increased production of platelets would improve clotting abilities and reduce the risk of ecchymoses.
D) This choice is incorrect because elevated levels of red blood cells would not directly cause ecchymoses on the skin. It may lead to other symptoms like increased blood viscosity.
Explanation
A) This choice is incorrect because impaired wound healing is not a typical cause of enlarged gums and bleeding in leukemia.
B) This choice is incorrect because a hyperactive immune response is not directly related to oral symptoms in leukemia.

B) This choice is correct. The exact cause of leukemia is not fully understood, and it can vary among individuals. It is believed to result from a combination of genetic mutations and environmental factors, but no single cause has been identified for all cases.
C) This choice is incorrect because while genetic mutations can play a role in the development of some types of leukemia, they are not the only cause. Environmental factors and other unknown factors also contribute to leukemia.
D) This choice is incorrect because while environmental toxins and pollution may be risk factors for some individuals, they are not the leading factors in all cases of leukemia.
Deep Vein Thrombosis
Explanation
A) This choice is correct. Avoiding sitting for long periods during long flights is a recommended preventive measure for individuals at risk of DVT. Prolonged immobility can increase the risk of blood clot formation in the legs during travel.
B) This choice is incorrect. Stopping prescribed anticoagulant medication increases the risk of blood clot formation and should never be done without the guidance of a healthcare provider. Anticoagulants are often prescribed to prevent or treat DVT and reduce the risk of clot progression or recurrence.
C) This choice is correct. Wearing compression stockings, as directed by a healthcare provider, can help prevent DVT by improving blood flow in the legs and reducing the risk of clot formation.
D) This choice is correct. Staying hydrated and drinking plenty of water can help prevent DVT by maintaining adequate blood volume and circulation. Dehydration can increase the risk of blood clot formation.
Explanation
A) This choice is incorrect because auscultating the lungs for crackles is not directly related to confirming the presence of deep vein thrombosis (DVT). Lung auscultation may be performed to assess for potential complications of DVT, such as pulmonary embolism.
B) This choice is correct. Homans' sign is a clinical test used to assess for the presence of DVT. The nurse flexes the client's knee and gently dorsiflexes the foot. A positive Homans' sign is indicated by calf pain or discomfort during dorsiflexion and may suggest the presence of a blood clot in the deep veins of the leg.
C) This choice is incorrect because measuring blood pressure in both arms is not a specific assessment for deep vein thrombosis (DVT). It may be done as part of a routine assessment but does not confirm the presence of DVT.
D) This choice is incorrect because performing a capillary refill test is not specific to DVT assessment. Capillary refill is a measure of peripheral perfusion and may be useful in assessing overall circulatory status, but it does not directly confirm the presence of DVT.
Explanation
A) This choice is incorrect because while relieving leg pain and swelling is an important aspect of DVT treatment, the primary goal is to prevent the clot from dislodging and causing a pulmonary embolism or other complications.
B) This choice is correct. The primary goal of DVT treatment is to prevent the clot from dislodging and traveling to the lungs, where it can cause a potentially life-threatening pulmonary embolism. Anticoagulant therapy and other interventions are used to stabilize the clot and prevent its migration.
C) This choice is incorrect because eliminating the risk factors for DVT is not the primary goal of treatment for a client who already has DVT. Preventing clot progression and complications take precedence over addressing risk factors at this stage.
D) This choice is incorrect because while administering anticoagulant therapy is a common treatment for DVT, it is a specific intervention rather than the primary goal. Anticoagulants help prevent the clot from growing and reduce the risk of embolism.
Explanation
A) This choice is correct. Encouraging active range of motion exercises helps prevent deep vein thrombosis (DVT) by promoting blood flow and reducing stasis in the veins. Moving the legs and ankles regularly helps prevent clot formation in immobilized clients.
B) This choice is incorrect because low-dose aspirin is not specifically indicated for preventing DVT. While aspirin may have some antiplatelet effects, it is not the primary preventive measure for DVT in high-risk clients.
C) This choice is incorrect because applying a heating pad to the affected leg is not a preventive measure for DVT. Heat application is not recommended for DVT prevention and could cause burns or injury.
D) This choice is incorrect because providing a soft mattress for the client's bed does not directly prevent DVT. The focus should be on encouraging movement and mobility to prevent DVT in clients at risk.
Explanation
A) This choice is correct. Warfarin is an anticoagulant that works by inhibiting the synthesis of vitamin K-dependent clotting factors. Clients on warfarin should be advised to avoid significant fluctuations in vitamin K intake, as found in foods like leafy greens and other green vegetables, to maintain consistent anticoagulation levels.
B) This choice is incorrect because discontinuing warfarin suddenly can increase the risk of blood clot formation and other complications. Clients should follow their healthcare provider's instructions for warfarin dosing and management.
C) This choice is incorrect because taking warfarin with grapefruit juice is not recommended and may not improve medication absorption. Grapefruit juice can interfere with the metabolism of some medications, but it is not a recommended method for enhancing warfarin absorption.
D) This choice is incorrect because clients on warfarin should be cautious about taking over-the-counter pain medications, especially nonsteroidal anti-inflammatory drugs (NSAIDs), which can increase the risk of bleeding. Clients should consult their healthcare provider before taking any new medications while on warfarin.
Questions
Explanation
A) This choice is incorrect because age and family history are non-modifiable risk factors for DVT. While they may increase the risk, they cannot be changed or controlled by the client.
B) This choice is incorrect because stopping prescribed anticoagulant medication is not recommended and may increase the risk of DVT. Anticoagulants are often prescribed to prevent or treat DVT and should not be discontinued without healthcare provider guidance.
C) This choice is correct. Smoking is a modifiable risk factor for DVT, and quitting smoking can reduce the risk of blood clot formation and other cardiovascular complications.
D) This choice is incorrect because while the client may have difficulty controlling a sedentary lifestyle, it is still considered a modifiable risk factor for DVT. Engaging in regular physical activity can help reduce the risk of blood clot formation.
Explanation
A) This choice is incorrect because a family history of high cholesterol is not directly related to DVT risk. While high cholesterol may contribute to other cardiovascular conditions, it is not a primary risk factor for DVT.
B) This choice is incorrect because a history of asthma is not a direct risk factor for DVT. Asthma is a respiratory condition and is not significantly associated with blood clot formation.
C) This choice is correct. Prolonged immobility during long flights, especially in cramped spaces, is a known risk factor for DVT. This condition is often referred to as "economy class syndrome" due to its association with long-haul flights in tight seating.
D) This choice is incorrect because the use of medications for diabetes does not directly relate to DVT risk. While some medications may influence blood clotting, diabetes itself is not a primary risk factor for DVT.
Explanation
A) This choice is correct. Gender is a non-modifiable risk factor for DVT, with women generally having a higher risk than men. Hormonal changes, such as those associated with pregnancy, oral contraceptives, and hormone replacement therapy, can contribute to the increased risk in women.
B) This choice is incorrect because obesity is a modifiable risk factor for DVT, not a non-modifiable one. Clients can work to achieve and maintain a healthy weight to reduce their risk.
C) This choice is incorrect because smoking history is a modifiable risk factor for DVT. Clients can quit smoking to decrease their risk of blood clot formation.
D) This choice is incorrect because a sedentary lifestyle is a modifiable risk factor for DVT. Clients can engage in regular physical activity to reduce their risk.
Explanation
A) This choice is incorrect because DVT is not caused by a bacterial infection in the blood vessels. It is primarily related to the formation of blood clots within the veins due to various risk factors.
B) This choice is incorrect because while injuries may be associated with DVT in some cases, they are not the primary cause. The formation of blood clots in the veins remains the underlying cause.
C) This choice is incorrect because atherosclerosis in the arteries is not the main cause of DVT. Atherosclerosis is a condition that involves the buildup of plaque in the arteries, not the veins.
D) This choice is correct. Deep vein thrombosis (DVT) is primarily caused by the formation of blood clots within the veins, typically in the lower extremities. These clots can obstruct blood flow and may lead to serious complications if not treated promptly.
Explanation
A) This choice is incorrect because advanced age is a non-modifiable risk factor for DVT. While age is associated with increased risk, it is not directly related to the client's use of hormonal therapy.
B) This choice is incorrect because male gender is not a risk factor for DVT. Women, particularly those on estrogen-based therapies like hormone replacement therapy or oral contraceptives, are at higher risk.
C) This choice is incorrect because smoking history is a modifiable risk factor for DVT, not directly related to hormonal therapy. Smoking increases the risk of clot formation and is not specific to the client's use of hormonal therapy.
D) This choice is correct. Estrogen-based hormone replacement therapy and oral contraceptives can increase the risk of DVT due to their effect on blood coagulation. Estrogen can increase the production of certain clotting factors, raising the risk of blood clot formation in the veins. It is essential for healthcare providers to weigh the benefits and risks when prescribing hormonal therapy to clients.
Questions
Explanation
A) This choice is incorrect because chest pain and shortness of breath are more indicative of a potential pulmonary embolism, a serious complication of DVT. While DVT can lead to a pulmonary embolism, the primary manifestation of DVT is related to the affected limb.
B) This choice is correct. Warmth and redness over the affected area, typically the calf or thigh, are common clinical manifestations of DVT. The warmth is due to the inflammatory response caused by the blood clot formation.
C) This choice is incorrect because pedal edema and bilateral leg pain are non-specific findings and can be caused by various conditions, not just DVT. They are not specific enough to diagnose DVT on their own.
D) This choice is incorrect because weak pedal pulses and cool extremities are not typically associated with DVT. These findings suggest potential arterial insufficiency rather than venous thrombosis.
Explanation
A) This choice is incorrect because palpating the pulses in the extremities primarily assesses arterial blood flow, not venous thrombosis. While pulse assessment is essential, it is not the priority for identifying DVT-related manifestations.
B) This choice is correct. Measuring calf and thigh circumference can help identify possible DVT by comparing the affected leg's size to the unaffected one. DVT can cause localized swelling in the affected limb.
C) This choice is incorrect because auscultating the lungs for crackles is not a specific assessment for DVT. Crackles may be present in pulmonary edema, which can be a complication of DVT, but they do not directly assess the presence of a blood clot in the veins.
D) This choice is incorrect because performing a capillary refill test is primarily used to assess peripheral perfusion and is not specific to DVT assessment.
Explanation
A) This choice is incorrect because swelling and redness in the affected leg are common clinical manifestations of DVT but are not specific to detecting potential complications like a pulmonary embolism. The nurse should focus on respiratory and cardiovascular assessments for this purpose.
B) This choice is incorrect because elevated body temperature and chills may indicate an infection but are not specific to detecting potential complications of DVT, such as a pulmonary embolism.
C) This choice is correct. Pleuritic chest pain (sharp chest pain worsened by deep breathing or coughing) and hemoptysis (coughing up blood) are classic clinical manifestations of a pulmonary embolism, a potentially life-threatening complication of DVT.
D) This choice is incorrect because abdominal pain and distension are not typical signs of a pulmonary embolism. Abdominal pain may be related to other causes, such as gastrointestinal issues.
Explanation
A) This choice is incorrect because arterial blood gas (ABG) analysis assesses oxygen and carbon dioxide levels in the blood, primarily used for respiratory and acid-base evaluations, not for confirming DVT.
B) This choice is correct. The D-dimer blood test is a screening test used to detect the presence of blood clot breakdown products in the blood. Elevated levels of D-dimer may suggest the presence of a blood clot, prompting further diagnostic testing for DVT.
C) This choice is incorrect because an electrocardiogram (ECG) primarily assesses the electrical activity of the heart and is not specific to confirming DVT. It may be useful to assess cardiac function in individuals with suspected pulmonary embolism.
D) This choice is incorrect because a chest X-ray is not used to confirm DVT. It is helpful in assessing the lungs and heart, particularly for detecting potential complications of DVT like a pulmonary embolism, but it does not directly diagnose DVT.
Explanation
A) This choice is incorrect because while monitoring blood pressure is essential, it is not the priority action for clients on anticoagulant therapy. The primary concern is assessing the client's response to the medication and their risk of bleeding.
B) This choice is correct. Monitoring the client's prothrombin time (PT) and international normalized ratio (INR) is crucial in assessing the effectiveness of anticoagulant therapy. The PT and INR measure how long it takes the blood to clot and help determine the appropriate dosage of anticoagulants to achieve the desired therapeutic effect.
C) This choice is incorrect because checking the client's blood glucose levels is not directly related to monitoring the response to anticoagulant therapy. Blood glucose monitoring is essential for clients with diabetes but not a priority in this context.
D) This choice is incorrect because evaluating the client's respiratory rate and pattern is not the priority action for monitoring the response to anticoagulant therapy. Respiratory assessment is vital in detecting potential complications like a pulmonary embolism but does not directly assess the client's anticoagulation status.
Questions
Explanation
A) This choice is incorrect because venous Doppler ultrasound is a non-invasive imaging test commonly used to diagnose DVT. However, it is not considered the gold standard due to potential limitations in visualizing small clots and deep veins.
B) This choice is incorrect because the D-dimer blood test is a screening test used to detect the presence of blood clot breakdown products. While it can help rule out DVT when negative, it is not the definitive diagnostic test.
C) This choice is incorrect because magnetic resonance imaging (MRI) is a sensitive imaging modality but is not considered the gold standard for diagnosing DVT. MRI may be used in specific cases, but contrast venography remains the gold standard.
D) This choice is correct. Contrast venography involves injecting contrast dye into the veins and taking X-ray images to visualize the blood flow and detect any clots. It is considered the gold standard for diagnosing DVT, as it provides direct visualization of the clot and the extent of its involvement.
Explanation
A) This choice is incorrect because while the D-dimer blood test is used to rule out DVT in low-risk individuals, the Wells score assessment is typically performed first to assess the client's pretest probability of DVT.
B) This choice is incorrect because magnetic resonance imaging (MRI) is not typically used as an initial diagnostic test for DVT. It may be employed in specific cases but is not the first-line test.
C) This choice is incorrect because a complete blood count (CBC) is a general blood test that does not directly assess the risk of DVT. It may provide information about overall health but is not specific to DVT assessment.
D) This choice is correct. The Wells score assessment is a validated tool used to estimate the likelihood of DVT based on clinical criteria and risk factors. It is commonly used as the first step in the diagnostic workup to determine if further testing, such as venous Doppler ultrasound or D-dimer blood test, is necessary.
Explanation
A) This choice is correct. The D-dimer blood test is a rapid and sensitive screening test that can help rule out DVT in low-risk individuals. A negative D-dimer result can be useful in excluding DVT, avoiding unnecessary imaging or invasive tests.
B) This choice is incorrect because contrast venography is not a rapid test and involves invasive procedures. It is not used as a first-line screening test due to its complexity and potential risks.
C) This choice is incorrect because magnetic resonance imaging (MRI) may provide valuable information, but it is not the first choice for rapid rule-out of DVT. MRI may be employed in specific cases when initial screening tests are inconclusive.
D) This choice is incorrect because the Wells score assessment is not a diagnostic test but a scoring system to estimate the likelihood of DVT. It does not provide rapid results to rule out DVT directly.
Explanation
A) This choice is incorrect because fasting is not necessary before a venous Doppler ultrasound. The client can eat and drink normally before the test.
B) This choice is incorrect because the client should continue to take prescribed medications as usual unless otherwise instructed by the healthcare provider. Medications that thin the blood, such as anticoagulants, may not be stopped before the test.
C) This choice is correct. The client should wear loose-fitting clothing that can be easily removed to allow access to the affected area during the ultrasound. This facilitates the ultrasound technician's ability to perform the test accurately.
D) This choice is incorrect because contrast dye is not typically used in a venous Doppler ultrasound. Contrast venography may involve the use of contrast dye, but not Doppler ultrasound.
Questions
Explanation
A) This choice is incorrect because anticoagulants do not dissolve existing blood clots in the veins. They prevent further clot formation and allow the body's natural mechanisms to dissolve the clot over time.
B) This choice is correct. Anticoagulants work by inhibiting the clotting factors in the blood, which prevents the formation of new blood clots and reduces the risk of the existing clot enlarging or causing additional complications.
C) This choice is incorrect because while anticoagulants may indirectly reduce pain and inflammation by preventing further clot formation, their primary action is to prevent clotting, not directly reduce pain and inflammation associated with DVT.
D) This choice is incorrect because while anticoagulants can improve blood flow by preventing clot formation, they do not directly "improve" blood flow to the affected limb.
Explanation
A) This choice is incorrect because compression stockings do not dissolve existing blood clots. Their primary purpose is to prevent new blood clots from forming by aiding blood flow and preventing stasis in the veins.
B) This choice is incorrect because while compression stockings may help reduce swelling in the affected leg by supporting venous return, their primary function is to prevent DVT and not specifically address swelling.
C) This choice is incorrect because compression stockings primarily target venous circulation in the legs and do not directly improve blood circulation throughout the entire body.
D) This choice is correct. Compression stockings exert pressure on the legs, assisting in venous return and preventing blood from pooling and clot formation. They are used as a preventive measure for individuals at risk of DVT or those diagnosed with DVT to reduce the risk of complications and recurrence.
Explanation
A) This choice is incorrect because monitoring prothrombin time (PT) and international normalized ratio (INR) is more relevant to monitoring oral anticoagulant therapy (e.g., warfarin) and not intravenous heparin therapy.
B) This choice is incorrect because while liver function tests may be important for some medications, they are not the priority for clients on intravenous heparin therapy. Heparin is primarily eliminated by the kidneys.
C) This choice is incorrect because while administering heparin via a central venous catheter is possible, it is not the priority action for safe administration. Monitoring the client's response to heparin therapy is more important.
D) This choice is correct. Monitoring the client's activated partial thromboplastin time (aPTT) is the priority action when administering intravenous heparin. The aPTT reflects the client's response to heparin and helps adjust the dosage to achieve the desired therapeutic effect while minimizing the risk of bleeding.
Explanation
A) This choice is correct. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Consistent vitamin K intake can impact the effectiveness of warfarin, so it is important for clients to maintain a stable vitamin K intake and avoid sudden changes in their diet.
B) This choice is incorrect because warfarin does not directly dissolve the blood clot in the leg. It prevents the formation of new clots and allows the body's natural mechanisms to dissolve the existing clot over time.
C) This choice is incorrect because while taking warfarin at the same time each day can help with adherence, the priority teaching point is about vitamin K intake and not the exact timing of the medication.
D) This choice is incorrect because discontinuing warfarin without medical guidance can be dangerous. Warfarin is typically prescribed for a specific duration, and its cessation should be guided by the healthcare provider based on the client's individual condition and risk factors.
A client with deep vein thrombosis (DVT) is prescribed enoxaparin, a low molecular weight heparin (LMWH). What is the nurse's priority action before administering the medication?
Explanation
A. Measuring the client's blood pressure is an important assessment but is not the immediate priority when preparing to administer enoxaparin.
B. Assessing the client's platelet count is critical before administering enoxaparin, especially because low molecular weight heparins can lead to heparin-induced thrombocytopenia (HIT). Monitoring platelet levels helps to ensure the client's safety and prevent complications.
C. Ensuring the client has an indwelling urinary catheter is not necessary for the administration of enoxaparin and does not relate to its safety or efficacy.
D. Obtaining the client's weight is relevant for dosing but is secondary to assessing the platelet count, particularly in light of the risk of HIT.
Explanation
A) This choice is incorrect because while isometric exercises can promote blood flow, the recommended preventive measure for DVT is wearing graduated compression stockings. Exercises alone may not be sufficient to prevent clot formation.
B) This choice is correct. Graduated compression stockings apply pressure to the lower extremities, improving blood flow and reducing the risk of stasis and clot formation. They are commonly used as a preventive measure for clients at risk of DVT, particularly after surgery or during prolonged immobility.
C) This choice is incorrect because limiting fluid intake is not a preventive measure for DVT and may not be safe or appropriate for all clients. Adequate hydration is essential to maintain blood volume and circulation.
D) This choice is incorrect because elevating the legs while resting is a recommended measure to improve blood flow and reduce edema, which can be beneficial. However, wearing graduated compression stockings is a more specific preventive measure for DVT.
Explanation
A) This choice is correct. Prolonged sitting or standing in one position can lead to reduced blood flow and stasis, increasing the risk of DVT. Encouraging regular movement and changing positions can help prevent clot formation.
B) This choice is incorrect because massaging the legs may not be suitable for everyone and is not a primary preventive measure for DVT. While it can aid in improving blood circulation, it should be done cautiously and not as a standalone preventive action.
C) This choice is incorrect because increasing the intake of vitamin K-rich foods is not a preventive measure for DVT. Vitamin K is involved in the clotting process, but it does not directly impact the risk of DVT.
D) This choice is incorrect because taking over-the-counter pain medications for leg discomfort does not prevent DVT. While pain management may be necessary for symptomatic relief, it does not address the underlying risk factors for DVT.
Explanation
A) This choice is correct. Performing calf-stretching exercises in the aisle can help improve blood circulation in the legs during a long flight and reduce the risk of stasis and clot formation.
B) This choice is incorrect because using a heating pad on the legs during a flight may not be feasible or safe. It is not a recommended preventive measure for DVT.
C) This choice is incorrect because wearing compression stockings during the flight is a recommended preventive measure for DVT. Compression stockings help improve blood flow and reduce the risk of clot formation during prolonged immobility.
D) This choice is incorrect because taking prescribed anticoagulant medication before boarding a flight is not a recommended preventive measure for all clients. The decision to take anticoagulant medication before a flight should be based on the client's individual risk factors and medical history.
Explanation
A) This choice is incorrect because regular physical activity is an essential preventive measure for DVT. Encouraging the client to engage in physical activity is vital for maintaining good circulation and reducing the risk of clot formation.
B) This choice is incorrect because a diet high in saturated fats and cholesterol is not a recommended preventive measure for DVT. A healthy, balanced diet is important for overall health, but it does not specifically prevent DVT.
C) This choice is incorrect because elevating the legs above heart level while resting is beneficial for reducing edema and improving blood flow but is not the primary preventive measure for DVT.
D) This choice is correct. The client should continue taking prescribed anticoagulant medication as directed by their healthcare provider. Anticoagulant therapy is often prescribed for a specific duration to prevent clot formation and reduce the risk of complications in clients with DVT.
Explanation
A) This choice is incorrect because mild leg swelling after prolonged standing may be expected, especially in clients with a history of DVT. It is not a critical symptom to report immediately.
B) This choice is correct. Redness and warmth at the site of the affected leg could indicate an inflammatory response or progression of the clot. These signs may be indicative of a potential complication, such as an infection or extension of the clot, and should be reported immediately for further evaluation and intervention.
C) This choice is incorrect because occasional cramping in the unaffected leg may not be directly related to the DVT. While any changes in leg symptoms should be reported to the healthcare provider, this symptom is less urgent than redness and warmth in the affected leg.
D) This choice is incorrect because mild fatigue and generalized body aches are non-specific symptoms and may not be directly related to DVT. While it is essential to report any new or concerning symptoms, redness and warmth in the affected leg are more indicative of potential complications related to DVT.
Questions
A nurse is caring for a client with suspected deep vein thrombosis (DVT). Which diagnostic test is used to assess blood flow and detect clots in the deep veins of the legs non-invasively?
Explanation
A) This choice is incorrect because the D-dimer blood test is a screening test for DVT but does not directly assess blood flow or detect clots non-invasively.
B) This choice is incorrect because magnetic resonance imaging (MRI) is a sensitive imaging modality, but it may not be readily available or suitable for all clients. It is not the primary choice for non-invasive assessment of blood flow and clots in suspected DVT.
C) This choice is incorrect because contrast venography is an invasive procedure involving the injection of contrast dye and X-ray imaging. It is not non-invasive, and venous Doppler ultrasound is a preferred first-line test.
D) This choice is correct. Venous Doppler ultrasound is a non-invasive imaging test used to assess blood flow in the veins and detect clots in the deep veins of the legs. It is readily available, safe, and does not involve the use of contrast dye or radiation.
Peripheral vascular disease
Explanation
A) This choice is incorrect because deep vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, typically in the legs. DVT is characterized by swelling, warmth, and redness in the affected leg, but it does not cause leg pain that improves with rest.
B) This choice is correct. Peripheral artery disease (PAD) is a condition where there is a narrowing or blockage of the arteries in the extremities, leading to reduced blood flow. The hallmark symptom of PAD is intermittent claudication, which is leg pain that occurs during walking or physical activity and improves with rest.
C) This choice is incorrect because Raynaud's disease is a disorder that affects the blood vessels in the fingers and toes, causing them to spasm and turn white, then blue, and finally red. It is not characterized by leg pain while walking.
D) This choice is incorrect because varicose veins are enlarged and twisted veins, usually in the legs, that can cause discomfort and cosmetic concerns. However, they do not typically cause leg pain that improves with rest.
Explanation
A) This choice is concerning and may indicate deep vein thrombosis (DVT). Swelling and tenderness in the calf can be a sign of a blood clot, and immediate evaluation is required to prevent potential complications such as a pulmonary embolism. However, it is not as critical as the finding in option D.
B) This choice is concerning and may indicate peripheral artery disease (PAD). Intermittent claudication during physical activity suggests reduced blood flow to the extremities, but it does not require immediate intervention.
C) This choice is concerning and may indicate Raynaud's disease. Raynaud's disease involves the fingers or toes turning white, then blue, and finally red due to blood vessel spasms, but it is not as urgent as the finding in option D.
D) This choice is correct. Ulceration on the lower leg with foul-smelling discharge indicates a severe complication of peripheral vascular disease, possibly related to peripheral artery disease (PAD) or venous insufficiency. Ulcers that have an unpleasant odor and are not healing require immediate intervention to prevent infection and further tissue damage.
Explanation
A) This choice is incorrect because while smoking can be a risk factor for deep vein thrombosis (DVT), diabetes and hypertension are not significant risk factors for this condition. DVT is more commonly associated with prolonged immobility, surgery, or trauma.
B) This choice is incorrect because Raynaud's disease is not directly related to smoking, diabetes, or hypertension. Raynaud's disease involves blood vessel spasms and is more commonly associated with exposure to cold temperatures or stress.
C) This choice is correct. Peripheral artery disease (PAD) involves the narrowing or blockage of arteries in the extremities, leading to reduced blood flow. Smoking, diabetes, and hypertension are significant risk factors for the development of PAD. Smoking damages blood vessels, diabetes increases the risk of atherosclerosis (plaque buildup in arteries), and hypertension can lead to arterial damage and narrowing.
D) This choice is incorrect because varicose veins are typically caused by weakened or damaged valves in the veins, leading to the pooling of blood and the development of enlarged and twisted veins. Smoking, diabetes, and hypertension are not primary risk factors for varicose veins.
Explanation
A) This choice is correct. Elevating the legs above heart level while sitting can improve venous return, reducing swelling and promoting blood circulation in the legs. This position helps counteract the effects of gravity on blood flow.
B) This choice is incorrect because applying direct heat to the affected extremities is not a recommended method for improving blood circulation in peripheral vascular disease. Heat can cause vasodilation, which may exacerbate symptoms such as swelling and pain.
C) This choice is incorrect because crossing the legs while seated can impede venous return and contribute to blood pooling in the legs. It is not a recommended activity for individuals with peripheral vascular disease.
D) This choice is incorrect because limiting physical activity is not recommended for individuals with peripheral vascular disease. Regular physical activity, such as walking, can actually improve blood circulation and overall vascular health. However, individuals with peripheral vascular disease should be cautious not to overexert themselves and should consult with their healthcare provider regarding appropriate levels of physical activity.
Questions
Explanation
A) This choice is correct. Smoking is the most significant risk factor for peripheral artery disease (PAD). Smoking damages blood vessels, promotes atherosclerosis (plaque buildup in arteries), and narrows blood vessels, leading to reduced blood flow to the extremities.
B) This choice is incorrect because while a sedentary lifestyle can be a contributing factor to peripheral vascular diseases, it is not the most common cause of PAD.
C) This choice is incorrect because while family history can play a role in the development of PAD, it is not the most common cause. Other modifiable risk factors, such as smoking and diabetes, have a more significant impact on PAD.
D) This choice is incorrect because high dietary sodium intake is not a direct cause of PAD. However, reducing sodium intake can benefit overall cardiovascular health, especially for individuals with hypertension.
Explanation
A) This choice is incorrect because decreased blood glucose levels are not associated with an increased risk of peripheral vascular disease (PAD) in diabetes. In fact, hypoglycemia (low blood glucose levels) can lead to acute complications but is not a significant factor in the development of PAD.
B) This choice is incorrect because increased insulin production is not a primary factor contributing to PAD in diabetes. Insulin is essential for glucose metabolism but does not directly impact blood vessel function.
C) This choice is correct. Diabetes can lead to impaired blood vessel function, primarily through the process of atherosclerosis. High blood glucose levels can damage blood vessel walls, leading to plaque buildup and narrowing of the arteries, reducing blood flow to the extremities and contributing to PAD.
D) This choice is incorrect because an elevated white blood cell count is not directly related to the increased risk of PAD in diabetes. While chronic inflammation and white blood cell count can play a role in atherosclerosis, it is not the primary factor contributing to PAD in diabetes.
Explanation
A) This choice is incorrect because hypertension (high blood pressure) is not a significant risk factor for venous insufficiency. Venous insufficiency involves the impairment of venous valves and blood flow in the veins, not arterial hypertension.
B) This choice is incorrect because atherosclerosis is associated with peripheral artery disease (PAD), not venous insufficiency. Atherosclerosis involves the buildup of plaque in the arteries, leading to reduced blood flow in the extremities.
C) This choice is correct. Deep vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, most commonly in the legs. DVT can lead to damage to the venous valves and veins, causing venous insufficiency and complications such as chronic venous insufficiency and venous ulcers.
D) This choice is incorrect because Raynaud's disease primarily affects the fingers and toes, causing them to spasm and change color in response to cold or stress. It is not directly related to the development of venous insufficiency.
Explanation
A) This choice is incorrect because increased blood viscosity (thickness) is not primarily associated with hypertension, hyperlipidemia, or obesity. It is more commonly associated with conditions such as polycythemia or dehydration.
B) This choice is incorrect because hypercoagulability of the blood is not a direct risk factor associated with hypertension, hyperlipidemia, or obesity. Hypercoagulability is more commonly associated with conditions such as certain clotting disorders.
C) This choice is incorrect because impaired cardiac function is not a direct risk factor for the development of PAD in the context of hypertension, hyperlipidemia, or obesity. However, impaired cardiac function can contribute to heart-related peripheral vascular diseases, such as congestive heart failure.
D) This choice is correct. Hypertension, hyperlipidemia, and obesity are significant risk factors for the formation of atherosclerotic plaques in the arteries. Atherosclerosis involves the buildup of plaque, including cholesterol and other substances, on the arterial walls, leading to narrowed and hardened arteries, reducing blood flow to the extremities and contributing to PAD.
Explanation
A) This choice is correct. As individuals age, the risk of peripheral vascular diseases increases due to several factors, including the weakening of arterial walls and the accumulation of plaque in the arteries (atherosclerosis). Aging is associated with changes in blood vessels, such as decreased elasticity and increased stiffness, which can contribute to the development of peripheral vascular diseases.
B) This choice is incorrect because while physical fitness can influence the risk of cardiovascular diseases, age-related changes in blood vessels can still increase the risk of peripheral vascular diseases, even in physically fit individuals.
C) This choice is incorrect because the risk of peripheral vascular diseases does not remain stable with no significant changes. Aging is associated with various physiological changes that can impact cardiovascular health and increase the risk of peripheral vascular diseases.
D) This choice is incorrect because while gender and ethnicity can influence the risk of certain conditions, age is a significant independent risk factor for the development of peripheral vascular diseases. The age-related changes in blood vessels apply to individuals of all genders and ethnicities.
Questions
Explanation
A) This choice is correct. Intermittent claudication is a hallmark symptom of peripheral arterial disease (PAD). It refers to pain, cramping, or weakness in the legs that occurs during physical activity and is relieved by rest. This symptom is due to reduced blood flow and oxygen supply to the muscles during exercise.
B) This choice is incorrect because deep vein thrombosis (DVT) typically presents with symptoms such as swelling, warmth, and tenderness in the affected leg, but it does not cause pain that is relieved by rest.
C) This choice is incorrect because Raynaud's phenomenon primarily affects the fingers and toes, causing them to turn white, then blue, and finally red due to blood vessel spasms in response to cold or stress. It is not associated with pain in the legs during walking.
D) This choice is incorrect because chronic venous insufficiency involves symptoms such as leg swelling, skin changes, and the development of venous ulcers, but it is not characterized by pain that occurs with walking and is relieved by rest.
Explanation
A) This choice is correct. A non-healing ulcer on the lower leg is a significant concern and requires immediate intervention. Non-healing ulcers can be a complication of peripheral vascular disease and may indicate impaired blood flow and tissue damage. Prompt assessment and treatment are necessary to prevent infection and promote wound healing.
B) This choice is incorrect because occasional leg cramps at night can be a common symptom, especially in older adults, and are not typically indicative of an acute medical emergency.
C) This choice is incorrect because mild coolness of the feet bilaterally can be a sign of reduced blood flow, but it is not an immediate concern requiring urgent intervention. However, it should be further assessed to determine the severity of the vascular condition.
D) This choice is incorrect because visible varicose veins on the calves, while often a cosmetic concern, are not typically associated with immediate risks. Varicose veins are dilated and twisted veins that result from venous insufficiency but are not an urgent medical condition.
Explanation
A) This choice is incorrect because using heating pads to warm cold feet can cause burns or injuries, especially in clients with impaired sensation due to peripheral vascular disease. Clients with PAD may experience cold feet due to reduced blood flow, but external heating sources should be used with caution.
B) This choice is incorrect because moisturizing the skin is essential for individuals with peripheral vascular disease to prevent dryness and cracking, which can lead to skin breakdown and infections. Proper skin care is important to maintain skin integrity and prevent complications.
C) This choice is correct. Clients with peripheral vascular disease should inspect their feet daily for any changes, such as cuts, sores, blisters, or signs of infection. Reduced blood flow can slow down wound healing, and prompt identification and treatment of foot problems are crucial to prevent infections and potential complications.
D) This choice is incorrect because while elevating the legs above heart level can temporarily improve blood flow and reduce swelling, prolonged elevation can impede blood flow and is not recommended for extended periods. Clients with PAD should be encouraged to perform regular, moderate physical activity to improve blood circulation.
Explanation
A) This choice is correct. Numbness and tingling in the feet are symptoms associated with arterial insufficiency in peripheral vascular disease (PAD). Reduced blood flow to the extremities can lead to sensory changes and discomfort, including numbness and tingling.
B) This choice is incorrect because venous insufficiency is more commonly associated with symptoms such as leg swelling, skin changes, and the development of venous ulcers, but it does not typically cause numbness and tingling in the feet.
C) This choice is incorrect because peripheral nerve compression can cause localized numbness and tingling, but it is not a primary symptom of peripheral vascular disease. Peripheral nerve compression may occur due to various factors, such as nerve impingement or entrapment.
D) This choice is incorrect because systemic inflammation is not a direct cause of numbness and tingling in the feet in peripheral vascular disease. Systemic inflammation can contribute to other conditions, but it is not the primary cause of sensory changes associated with PAD.
A client with peripheral vascular disease (PAD) is prescribed cilostazol, a medication that improves blood flow in the legs. The nurse should instruct the client to:
Explanation
For a client with peripheral vascular disease (PAD) who is prescribed cilostazol, the nurse should provide the following instruction:
C) Avoid grapefruit juice while on cilostazol.
Grapefruit juice can interact with certain medications, including cilostazol, and may lead to increased levels of the medication in the bloodstream. This can potentially cause adverse effects or interfere with the intended therapeutic effects of cilostazol. Therefore, clients taking cilostazol should be advised to avoid grapefruit juice.
The other options are not appropriate:
A) Increasing the dosage of cilostazol without consulting a healthcare provider is not recommended and can be dangerous.
B) Cilostazol can be taken with or without food, so taking it on an empty stomach is not necessary.
D) While compression stockings can be used for some individuals with PAD, their use should be discussed with the healthcare provider and is not specific to cilostazol instructions.
Explanation
A) This choice is incorrect because angiography is an invasive procedure that involves the injection of contrast dye into the blood vessels to visualize their structure and blood flow. It is not a non-invasive test.
B) This choice is incorrect because venography is an imaging test that involves the injection of contrast dye into a vein to visualize its flow. It is not commonly used to assess blood flow and blood pressure in the legs.
C) This choice is correct. Doppler ultrasound is a non-invasive test that uses sound waves to assess blood flow and blood pressure in the legs. It helps identify areas of reduced blood flow, blockages, and abnormalities in the blood vessels.
D) This choice is incorrect because magnetic resonance imaging (MRI) is a diagnostic imaging technique that provides detailed images of the body's internal structures using a magnetic field and radio waves. While it can be used to assess blood vessels, it is not the primary test for evaluating blood flow in peripheral vascular diseases.
Explanation
A) This choice is correct. The ankle-brachial index (ABI) is a non-invasive test that compares the blood pressure in the arms and legs. The test involves using a blood pressure cuff and Doppler ultrasound to measure blood pressure in the ankles and arms. The ratio of ankle to brachial pressure helps assess the severity of peripheral vascular disease and determine if there is reduced blood flow to the legs.
B) This choice is incorrect because oxygen saturation in the extremities is not directly measured with an ankle-brachial index (ABI) test. Oxygen saturation is commonly measured using pulse oximetry, which assesses the percentage of hemoglobin in the blood that is saturated with oxygen.
C) This choice is incorrect because an ankle-brachial index (ABI) test is not used to measure blood glucose levels before and after meals. Blood glucose levels are typically assessed using a blood test or fingerstick glucose monitoring in clients with diabetes.
D) This choice is incorrect because an ankle-brachial index (ABI) test does not evaluate blood flow through the heart's chambers. It focuses on assessing blood pressure and blood flow in the arms and legs to diagnose peripheral vascular disease.
Explanation
A) This choice is incorrect because asthma is not directly associated with an increased risk of atherosclerosis or peripheral vascular disease. Asthma is a chronic respiratory condition that affects the airways, not the blood vessels.
B) This choice is incorrect because osteoarthritis is a degenerative joint disease and is not directly linked to an increased risk of atherosclerosis or peripheral vascular disease.
C) This choice is incorrect because while hypothyroidism can impact cardiovascular health, it is not a primary risk factor for atherosclerosis or peripheral vascular disease. Hypothyroidism can lead to elevated cholesterol levels, but hypercholesterolemia is the specific condition related to increased cholesterol levels and atherosclerosis.
D) This choice is correct. Hypercholesterolemia, characterized by high levels of cholesterol in the blood, is a significant risk factor for atherosclerosis, which is the buildup of plaque in the arterial walls. Atherosclerosis is a common cause of peripheral vascular disease, leading to reduced blood flow to the extremities and various cardiovascular complications.
Explanation
A) This choice is incorrect because arteriography is an invasive procedure that involves the insertion of a catheter through a blood vessel, typically in the groin or arm, to inject contrast dye directly into the arteries. It is not performed using a small incision in the leg.
B) This choice is incorrect because keeping the leg immobile after an arteriography is not necessary. However, the client will be asked to rest and avoid strenuous activities for a few hours following the procedure.
C) This choice is incorrect because the procedure that uses sound waves to visualize blood flow is a Doppler ultrasound, not an arteriography. Arteriography involves the use of contrast dye and X-rays to visualize the arterial blood vessels.
D) This choice is correct. Arteriography requires the use of contrast dye to enhance the visualization of blood vessels during X-ray imaging. There is a risk of an allergic reaction to the contrast dye, and clients should be informed about this potential complication before the procedure. Precautions may be taken, and the client's medical history should be reviewed to identify any contraindications to the use of contrast dye.
Explanation
A) This choice is incorrect because cardiac catheterization is an invasive procedure that involves the insertion of a catheter into the heart chambers or coronary arteries. It is used to assess the heart's structure and function, not blood flow in the legs.
B) This choice is incorrect because an electrocardiogram (ECG/EKG) is a non-invasive test that records the electrical activity of the heart to assess heart rate and rhythm. It is not used to assess blood flow in the legs.
C) This choice is correct. Magnetic resonance angiography (MRA) is a non-invasive imaging technique that uses a magnetic field and radio waves to create detailed images of blood vessels. It can assess blood flow in the legs, identify blockages, and provide valuable information about the vascular status of the extremities.
D) This choice is incorrect because a pulmonary function test (PFT) is a test used to assess lung function and diagnose respiratory conditions. It is not used to assess blood flow in the legs or detect peripheral vascular disease.
Questions
Explanation
A) This choice is incorrect because headache is a common side effect of cilostazol but is generally not a severe adverse reaction that requires immediate reporting. Headaches can be managed with over-the-counter pain relievers if needed.
B) This choice is incorrect because diarrhea is a known side effect of cilostazol but is not typically severe or life-threatening. Clients should be encouraged to stay hydrated and notify their healthcare provider if it becomes bothersome.
C) This choice is incorrect because muscle cramps can occur as a side effect of cilostazol, but they are not considered an urgent adverse reaction. Mild muscle cramps can often be managed with stretching and hydration.
D) This choice is correct. Dizziness is a significant adverse effect of cilostazol and should be reported immediately. Cilostazol can cause a drop in blood pressure, leading to dizziness, lightheadedness, and a risk of falls. If a client experiences severe dizziness or fainting, they should seek medical attention promptly.
Explanation
A) This choice is incorrect because encouraging prolonged standing can worsen symptoms of chronic venous insufficiency (CVI). Prolonged standing increases venous pressure in the legs and can lead to further swelling and discomfort.
B) This choice is correct. Elevating the legs above heart level when resting is a beneficial intervention for individuals with chronic venous insufficiency (CVI). Elevating the legs helps improve venous return and reduces swelling in the legs.
C) This choice is incorrect because applying warm compresses to the legs may provide temporary relief for some individuals, but it is not a primary intervention for managing chronic venous insufficiency (CVI).
D) This choice is incorrect because tight-fitting compression stockings are commonly used to manage chronic venous insufficiency (CVI), but they should be fitted appropriately by a healthcare professional. Wearing overly tight compression stockings can impede blood flow and cause discomfort.
Explanation
A) This choice is incorrect because while administering analgesics for pain relief is important for the client's comfort, it is not the priority in this situation. The non-healing ulcer may require further assessment and interventions beyond pain relief.
B) This choice is correct. In a client with peripheral arterial disease (PAD) and a non-healing foot ulcer, there is a risk of infection due to reduced blood flow and compromised tissue healing. Initiating prophylactic antibiotics is a priority to prevent or manage infection and promote wound healing.
C) This choice is incorrect because elevating the affected foot can be beneficial to improve blood flow in individuals with venous insufficiency or edema but may not be as effective for individuals with peripheral arterial disease (PAD).
D) This choice is incorrect because promoting regular foot inspections is essential for clients with peripheral vascular diseases, but in this case, the non-healing ulcer requires immediate attention. Proper wound care, including assessment, cleaning, and dressing, should be part of the client's plan of care, but antibiotic therapy is the priority in this situation.
Explanation
A) This choice is incorrect because limiting fluid intake is not a standard post-procedure instruction following angioplasty with stent placement. Adequate hydration is important for recovery and overall health.
B) This choice is incorrect because walking is generally encouraged following angioplasty with stent placement. Early mobilization helps prevent complications such as blood clots and promotes blood flow through the treated vessel.
C) This choice is correct. After angioplasty with stent placement, clients are often prescribed dual antiplatelet therapy, which typically includes aspirin and another antiplatelet medication such as clopidogrel. Dual antiplatelet therapy helps prevent blood clots from forming around the stent and reduces the risk of stent re-narrowing (restenosis).
D) This choice is incorrect because applying ice packs to the incision site is not a standard post-procedure instruction after angioplasty with stent placement. Ice packs are not typically used for this type of procedure, and the incision site is usually managed with sterile dressings and wound care.
Questions
Explanation
A) This choice is incorrect because increasing sodium intake can lead to fluid retention and exacerbate swelling, which is counterproductive for clients with peripheral vascular disease (PAD).
B) This choice is incorrect because limiting fluid intake can lead to dehydration and is not typically recommended for individuals with PAD. Adequate hydration is important for overall health and vascular function.

A low-fat and low-cholesterol diet is essential for individuals with peripheral vascular disease (PAD) to reduce the buildup of plaque in the arteries (atherosclerosis) and improve blood flow. Lowering dietary intake of saturated fats and cholesterol helps manage cardiovascular risk factors.
D) This choice is incorrect because consuming high amounts of caffeine can lead to increased heart rate and blood pressure, which may be detrimental for clients with PAD. Moderate caffeine intake is generally recommended.
Explanation
A) This choice is incorrect because avoiding all physical activity can lead to deconditioning and worsen exercise tolerance over time. Regular exercise is beneficial for individuals with peripheral vascular disease (PAD) to improve blood flow and manage symptoms.
B) This choice is incorrect because waiting until the pain becomes severe and then stopping (known as the "stop-and-rest" method) is not recommended for individuals with PAD. This approach can lead to inadequate exercise and may not provide the benefits of regular walking.
C) This choice is incorrect because engaging in a daily high-intensity exercise regimen is not appropriate for individuals with PAD, especially if they experience intermittent claudication. High-intensity exercise can exacerbate leg pain and may not be well-tolerated.
D) This choice is correct. Gradually increasing walking distance over time is a recommended approach for individuals with PAD to improve exercise tolerance and manage intermittent claudication. The goal is to push the limits of walking distance without causing severe pain, allowing the individual to gradually build endurance and improve blood flow.
Explanation
A) This choice is incorrect because crossing the legs while sitting can impede blood flow and worsen symptoms of chronic venous insufficiency (CVI). Clients with CVI should avoid crossing their legs and keep them uncrossed to promote blood flow.
B) This choice is correct. Elevating the legs above heart level when resting is a beneficial self-care strategy for individuals with chronic venous insufficiency (CVI). Elevating the legs helps improve venous return, reduce swelling, and alleviate discomfort.
C) This choice is incorrect because while applying warm compresses may provide temporary relief for some individuals with CVI, it is not a primary self-care strategy for promoting venous return. Warm compresses may be more suitable for acute injuries or inflammation.
D) This choice is incorrect because while wearing compression stockings is a recommended intervention for individuals with CVI, tight-fitting compression stockings can impede blood flow and cause discomfort. Compression stockings should be fitted appropriately by a healthcare professional to ensure optimal efficacy.
Explanation
A) This choice is incorrect because soaking the feet in hot water is not recommended for individuals with peripheral vascular disease (PAD) or cold feet. Hot water can cause burns or injuries, especially in clients with reduced sensation due to PAD.
B) This choice is incorrect because while wearing thick socks can provide some insulation, it is not a comprehensive solution for managing cold feet caused by reduced blood flow.
C) This choice is incorrect because using an electric blanket may not be specific to the feet and may not effectively address the issue of cold feet due to PAD.
D) This choice is correct. Avoiding exposure to cold temperatures is a recommended self-care measure for individuals with peripheral vascular disease (PAD) experiencing cold feet. Cold temperatures can further constrict blood vessels and reduce blood flow to the extremities. Clients should keep their feet warm and protect them from cold weather using appropriate footwear and clothing.
Explanation
A) This choice is incorrect because while nicotine replacement therapy can be helpful for individuals trying to quit smoking, it is not the priority intervention. The primary goal is to promote smoking cessation itself, as it provides the most significant health benefits.
B) This choice is incorrect because smokeless tobacco is not a safe alternative to smoking and is not recommended for promoting vascular health. Smokeless tobacco still contains harmful substances that can damage blood vessels and increase cardiovascular risks.
C) This choice is correct. Providing education on the benefits of smoking cessation is a priority intervention for a client with peripheral vascular disease (PAD) who has a history of smoking. Smoking is a significant risk factor for PAD and other cardiovascular diseases. Quitting smoking can lead to immediate and long-term health improvements, including improved blood flow and reduced risk of complications.
D) This choice is incorrect because advising the client to smoke fewer cigarettes per day is not sufficient to address the adverse effects of smoking on vascular health . Smoking cessation is the most effective approach to improve vascular health and reduce the risk of PAD-related complications.
Questions
Explanation
A) This choice is incorrect because lying down and elevating the legs during episodes of intermittent claudication may provide temporary relief, but it does not address the underlying issue. Encouraging the client to stop and rest perpetuates the pain cycle and may hinder progress in managing PAD symptoms.
B) This choice is incorrect because deep breathing exercises are not directly related to managing intermittent claudication. While deep breathing exercises can be beneficial for relaxation and stress reduction, they do not specifically address the leg pain experienced during walking.
C) This choice is correct. Encouraging the client to continue walking during episodes of intermittent claudication helps build endurance and improves blood flow to the legs. Gradual increases in walking distance and duration can help the client tolerate longer periods of activity before experiencing pain.
D) This choice is incorrect because using a heating pad on the affected area is not recommended for managing intermittent claudication. Heat may not provide significant pain relief, and it does not address the underlying vascular issues causing the pain.
Explanation
A) This choice is incorrect because elevating the legs above heart level for only 15 minutes daily may not provide sufficient benefit for managing edema and skin changes in clients with chronic venous insufficiency (CVI). Continuous and prolonged elevation, along with compression therapy, is more effective in reducing swelling.
B) This choice is correct. Applying compression bandages or stockings is a standard intervention for managing edema and skin changes in clients with chronic venous insufficiency (CVI). Compression helps improve venous return and reduce swelling in the lower legs.
C) This choice is incorrect because soaking the legs in hot water is not recommended for clients with chronic venous insufficiency (CVI). Hot water may cause skin irritation and worsen skin changes associated with CVI.
D) This choice is incorrect because encouraging long periods of standing can worsen symptoms in clients with CVI. Prolonged standing increases venous pressure in the legs and can lead to further swelling and discomfort.
Explanation
A) This choice is incorrect because mild incisional pain is common after peripheral artery bypass surgery and may be managed with prescribed pain medications. However, severe or worsening pain should be reported to the healthcare provider.
B) This choice is incorrect because mild swelling in the feet is a common post-operative finding after peripheral artery bypass surgery and may resolve with time. However, excessive or sudden swelling should be reported to the healthcare provider.
C) This choice is correct. Pallor (pale color) and coolness of the affected foot may indicate reduced blood flow to the extremity, which could be a sign of a complication such as graft occlusion or clot formation. These signs should be reported immediately for prompt evaluation and intervention.
D) This choice is incorrect because tingling sensation in the legs is common after surgery and may be related to changes in blood flow or nerve irritation. It is not typically a sign that requires immediate reporting unless it is severe or accompanied by other concerning symptoms.
A client with peripheral vascular disease (PAD) is scheduled for a percutaneous transluminal angioplasty (PT with stent placement. What pre-procedure information should the nurse provide to the client?
Explanation
A) This choice is incorrect because avoiding eating or drinking for 24 hours before the procedure is not typically required for a percutaneous transluminal angioplasty (PTA) with stent placement. The client may be instructed to avoid eating or drinking for a few hours before the procedure to prevent aspiration during sedation, but a 24-hour fast is not necessary.
B) This choice is incorrect because percutaneous transluminal angioplasty (PTA) with stent placement is typically performed under local anesthesia or conscious sedation, not general anesthesia. General anesthesia is not required for this procedure.
C) This choice is incorrect because percutaneous transluminal angioplasty (PTA) with stent placement is a minimally invasive procedure that does not involve making a large incision in the abdomen. It is usually performed using small punctures or incisions in the groin or arm to insert a catheter.
D) This choice is correct. A percutaneous transluminal angioplasty (PTA) with stent placement involves the insertion of a catheter through a blood vessel, typically in the groin or arm, to reach the narrowed or blocked artery. The catheter is used to inflate a small balloon and place a stent to open the artery and improve blood flow. Providing information about the catheter insertion is essential for the client's understanding of the procedure.
Explanation
A) This choice is incorrect because encouraging the client to massage the legs daily may not be appropriate for individuals with peripheral vascular disease (PAD). Vigorous massage can damage fragile blood vessels and exacerbate skin breakdown or injury.
B) This choice is incorrect because applying adhesive tape directly to the skin can cause skin trauma and increase the risk of skin breakdown. Dressings should be secured using appropriate medical tapes or dressings that are designed for skin protection.
C) This choice is correct. Regularly inspecting the skin for redness, discoloration, or signs of breakdown is crucial for early detection of impaired skin integrity in clients with peripheral vascular disease (PAD). Prompt identification and intervention can help prevent the development of pressure ulcers or wounds.
D) This choice is incorrect because using a donut-shaped cushion for sitting is generally not recommended for preventing skin breakdown. Donut cushions can increase pressure on the area around the coccyx and may cause more harm than good. Clients at risk of skin breakdown should be repositioned regularly and encouraged to shift their weight to relieve pressure on vulnerable areas.
Questions
A nurse is providing education to a client about peripheral vascular diseases. The nurse explains that these diseases primarily affect which body system?
Explanation
A) This choice is incorrect because peripheral vascular diseases primarily affect the cardiovascular system, not the respiratory system. The respiratory system involves the lungs and the exchange of gases, while the cardiovascular system involves the heart and blood vessels.
B) This choice is correct. Peripheral vascular diseases are conditions that affect the blood vessels outside the heart and brain, including the arteries and veins in the extremities (arms and legs). These diseases can lead to reduced blood flow, pain, and various complications.
C) This choice is incorrect because peripheral vascular diseases do not primarily affect the nervous system. While some peripheral vascular diseases may have neurological implications, they are not primarily neurological disorders.
D) This choice is incorrect because peripheral vascular diseases do not primarily affect the gastrointestinal system. The gastrointestinal system involves the digestion and absorption of nutrients, which is not directly related to peripheral vascular diseases.
A nurse is providing education to a client with peripheral vascular disease (PAD). The nurse should instruct the client to perform which exercise to improve blood flow in the legs?
Explanation
A) This choice is incorrect because weightlifting is not typically recommended for individuals with peripheral vascular disease (PAD). High-intensity weightlifting can increase blood pressure and may not be suitable for clients with cardiovascular conditions.
B) This choice is incorrect because running, especially high-impact running, may be too strenuous for individuals with PAD and could lead to discomfort or injury. Low-impact exercises are generally preferred.
C) This choice is incorrect because high-impact aerobics can be too intense for individuals with PAD and may not be well-tolerated, especially if they experience leg pain during exercise.
D) This choice is correct. Walking is a low-impact exercise that can be beneficial for individuals with peripheral vascular disease. It promotes blood flow in the legs, increases circulation, and helps manage intermittent claudication (pain during walking) associated with PAD. Gradually increasing walking distance and duration can improve cardiovascular fitness and overall health.
Congestive Cardiac Failure
Explanation
A) This choice is incorrect because sudden weight gain, shortness of breath, and ankle swelling are not normal with CHF and may indicate worsening of the condition. The nurse should not reassure the client but rather take appropriate action to address the symptoms.
B) This choice is incorrect because the client's symptoms suggest fluid retention, and increasing fluid intake would exacerbate the condition. The nurse should not encourage the client to increase fluid intake without consulting the healthcare provider.
C) This choice is correct. The client's sudden weight gain, shortness of breath, and ankle swelling are signs of worsening congestive heart failure. The nurse's priority action is to notify the healthcare provider immediately to address the client's worsening condition and adjust the treatment plan as needed.
D) This choice is incorrect because administering a diuretic is not within the nurse's scope of practice without a healthcare provider's order. The nurse should first notify the healthcare provider to evaluate the client's condition and determine the appropriate intervention.
Explanation
A) This choice is correct. Hypertension (high blood pressure) is a significant risk factor for congestive heart failure (CHF). Prolonged hypertension can lead to the heart's increased workload, causing it to weaken over time and eventually leading to CHF. The client's symptoms of fatigue, difficulty breathing, and nocturia (frequent urination at night) are common manifestations of CHF resulting from uncontrolled hypertension.
B) This choice is incorrect because diabetes mellitus, while a risk factor for cardiovascular disease, is not directly associated with the symptoms described by the client. However, diabetes can exacerbate CHF if the client's blood glucose levels are not well-controlled.
C) This choice is incorrect because smoking history is a risk factor for various cardiovascular diseases, but it is not specifically linked to the symptoms reported by the client in this case.
D) This choice is incorrect because a family history of heart disease may increase the client's risk of developing CHF, but it does not directly contribute to the current symptoms the client is experiencing.
Explanation
A) This choice is incorrect because ascites (abdominal swelling due to fluid accumulation) is a sign of right-sided heart failure, not left-sided heart failure.
B) This choice is incorrect because dependent edema (swelling in the legs and ankles) is also a sign of right-sided heart failure, not left-sided heart failure.
C) This choice is correct. Crackles in the lungs, also known as rales, are the classic hallmark of left-sided heart failure. They occur when fluid accumulates in the lungs, leading to abnormal lung sounds on auscultation.
D) This choice is incorrect because jugular vein distention is associated with right-sided heart failure, not left-sided heart failure.
Explanation
A) This choice is incorrect because restricting all physical activity is not recommended for clients with congestive heart failure. Regular, moderate exercise can be beneficial for heart health when appropriately prescribed by the healthcare provider.
B) This choice is correct. Regularly weighing themselves, ideally daily, and reporting sudden weight gain to the healthcare provider is essential for clients with congestive heart failure. Sudden weight gain may indicate fluid retention, a worsening of heart failure, or medication non-compliance.
C) This choice is incorrect because a high-sodium diet can worsen fluid retention and exacerbate congestive heart failure symptoms. The client should follow a low-sodium diet to manage fluid balance.
D) This choice is incorrect because taking prescribed medications only when symptoms worsen is not appropriate for congestive heart failure management. The client should take prescribed medications as directed by the healthcare provider, even when feeling well, to prevent symptom exacerbation and improve heart function.
Explanation
A) This choice is incorrect because hypertension is not a common side effect of digoxin. Digoxin is used to treat heart failure and can help control blood pressure in some cases.
B) This choice is incorrect because hyperkalemia (elevated potassium levels) is not a common side effect of digoxin. In fact, digoxin can sometimes cause hypokalemia (low potassium levels) as a side effect.
C) This choice is correct. Bradycardia (slow heart rate) is a common side effect of digoxin. Digoxin works by increasing the force of the heart's contractions and can slow down the heart rate. Clients taking digoxin should have their heart rate monitored regularly, and the healthcare provider should be notified if the heart rate is below the prescribed parameters.
D) This choice is incorrect because respiratory alkalosis is not a common side effect of digoxin. Digoxin does not directly affect the respiratory system.
Questions
Explanation
A) This choice is incorrect because while infections and viral illnesses can contribute to heart failure in some cases, they are not the leading causes of CHF. Hypertension and coronary artery disease are more common risk factors.
B) This choice is correct. Hypertension (high blood pressure) and coronary artery disease (narrowing or blockage of the heart's blood vessels) are the leading causes of CHF. Both conditions place increased stress on the heart and can lead to heart muscle damage and failure.
C) This choice is incorrect because while excessive physical exertion and overworking the heart can contribute to heart failure, they are not the primary causes of CHF. Underlying conditions like hypertension and coronary artery disease are more significant risk factors.
D) This choice is incorrect because anemia and low red blood cell count can impact heart function, but they are not the main causes of CHF. Hypertension and coronary artery disease are more commonly associated with the development of CHF.
Explanation
A) This choice is correct. Alcohol abuse can lead to dilated cardiomyopathy, a condition in which the heart becomes enlarged and weakened, contributing to congestive heart failure. Chronic alcohol consumption can cause toxic effects on the heart muscle, leading to impaired pumping function.
B) This choice is incorrect because malnutrition, while it can impact overall health, is not a direct precipitating cause of congestive heart failure. However, malnutrition can exacerbate heart failure symptoms and weaken the heart further.
C) This choice is incorrect because a sedentary lifestyle can be a risk factor for heart disease, including congestive heart failure, but it is not a direct precipitating cause of the client's condition in this scenario.
D) This choice is incorrect because occupational exposure to toxins can have health implications, but it is not directly related to the client's signs and symptoms of congestive heart failure in this case.
Explanation
A) This choice is incorrect because a body mass index (BMI) of 22 kg/m² is within the normal range and is not directly associated with the development of congestive heart failure in this scenario.
B) This choice is incorrect because a blood pressure of 120/80 mmHg is within the normal range and does not indicate a direct precipitating factor for congestive heart failure in this case.
C) This choice is incorrect because a fasting blood glucose level of 90 mg/dL is within the normal range and is not directly associated with the development of congestive heart failure in this scenario.
D) This choice is correct. A serum cholesterol level of 240 mg/dL indicates high cholesterol, which is a risk factor for coronary artery disease. Coronary artery disease is a leading cause of congestive heart failure and may have contributed to the client's condition.
Explanation
A) This choice is incorrect because age is a non-modifiable risk factor for congestive heart failure. While age increases the risk of heart disease, including CHF, it cannot be changed or modified.
B) This choice is incorrect because family history of heart disease is a non-modifiable risk factor. While individuals with a family history of heart disease may have an increased risk of developing CHF, it is not something that can be changed or modified.
C) This choice is correct. Smoking is a modifiable risk factor for congestive heart failure. Smoking damages blood vessels, increases blood pressure, and can lead to atherosclerosis, all of which contribute to heart failure.
D) This choice is incorrect because gender is a non-modifiable risk factor for congestive heart failure. While men may have a slightly higher risk of heart failure compared to women, gender is not something that can be changed or modified.
Explanation
A) This choice is incorrect because while electrolyte imbalances can have cardiovascular implications, they are not directly associated with diabetes mellitus or congestive heart failure.
B) This choice is incorrect because left-sided heart failure is not directly related to uncontrolled diabetes mellitus. However, diabetes can exacerbate heart failure if not well-controlled due to its impact on blood vessels and the heart.
C) This choice is incorrect because decreased afterload is not directly related to uncontrolled diabetes mellitus. Afterload refers to the resistance the heart has to overcome to eject blood into the circulation.
D) This choice is correct. Uncontrolled diabetes mellitus can lead to microvascular damage, particularly in the small blood vessels of the heart. This damage can contribute to heart muscle dysfunction and congestive heart failure. Diabetes is a significant risk factor for developing heart failure.
Questions
Explanation
A) This choice is incorrect because orthopnea is a different symptom where the client experiences difficulty breathing while lying flat and finds relief by sitting upright or standing.
B) This choice is correct. Paroxysmal nocturnal dyspnea is characterized by sudden breathlessness that awakens the client from sleep, usually 1-2 hours after falling asleep. The client may feel the need to sit upright or dangle the legs to breathe comfortably.
C) This choice is incorrect because peripheral edema refers to swelling in the legs, ankles, and feet, which is a common symptom of congestive heart failure but does not match the client's reported symptom.
D) This choice is incorrect because tachypnea is rapid breathing and is not specifically related to the client's nighttime symptom of sudden breathlessness.
Explanation
A) This choice is incorrect because palpitations refer to an abnormal awareness of the heart's beating, which is not described by the client.
B) This choice is incorrect because angina pectoris is chest pain or discomfort due to inadequate blood flow to the heart muscle. The client's complaint is related to physical activity causing fatigue and weakness, not chest pain.
C) This choice is correct. Dyspnea on exertion refers to shortness of breath or difficulty breathing that occurs with physical activity or exertion. The client's symptoms of feeling fatigued and weak after mild activity suggest exertional dyspnea, which is common in congestive heart failure.
D) This choice is incorrect because peripheral cyanosis is bluish discoloration of the skin and mucous membranes due to reduced blood flow, which is not described by the client.
Explanation
A) This choice is incorrect because clubbing refers to the enlargement of the fingertips and nails due to chronic hypoxia, which is not related to the client's reported symptoms.
B) This choice is correct. Peripheral edema refers to swelling in the legs, ankles, and feet, which is a common symptom of congestive heart failure. The client's symptoms of swollen ankles, legs, and abdomen indicate peripheral edema.
C) This choice is incorrect because pitting edema is a specific type of edema where pressure on the skin leaves an indentation or "pit." While the client's edema may indeed be pitting, the question does not provide enough information to confirm this.
D) This choice is incorrect because ascites is the accumulation of fluid in the abdominal cavity and is not specific to the client's reported symptoms of swollen ankles and legs.
Explanation
A) This choice is incorrect because wheezing on auscultation is a characteristic finding in respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), not congestive heart failure.
B) This choice is incorrect because hyperactive bowel sounds are not specific to congestive heart failure and are more indicative of gastrointestinal activity.
C) This choice is incorrect because the absence of jugular vein distention is not directly related to fluid accumulation in the lungs. Jugular vein distention is associated with right-sided heart failure.
D) This choice is correct. Crackles, also known as rales, are abnormal lung sounds heard on auscultation and may indicate fluid accumulation in the lungs, a common symptom of congestive heart failure. The presence of crackles suggests pulmonary congestion due to fluid leaking into the alveoli.
Explanation
A) This choice is incorrect because hemoptysis refers to coughing up blood from the respiratory tract, which is not described by the client.
B) This choice is incorrect because dyspnea refers to difficulty breathing or shortness of breath, not a dry, persistent cough.
C) This choice is incorrect because paroxysmal nocturnal dyspnea is characterized by sudden breathlessness that awakens the client from sleep, not a dry cough.
D) This choice is correct. Cardiac asthma is a form of wheezing or coughing that occurs as a result of fluid accumulation in the lungs due to congestive heart failure. It is not caused by asthma but is a manifestation of heart failure impacting the respiratory system.
Questions
Explanation
A) This choice is incorrect because an electrocardiogram (ECG) is a valuable diagnostic tool for assessing the heart's electrical activity and rhythm, but it is not the gold standard for diagnosing CHF. It can provide information about possible cardiac hypertrophy or rhythm disturbances associated with heart failure.
B) This choice is incorrect because a chest X-ray is helpful in evaluating heart size and the presence of pulmonary congestion, but it is not the gold standard for diagnosing CHF.
C) This choice is correct. An echocardiogram is the gold standard for diagnosing CHF. It uses ultrasound waves to assess the heart's structure and function, including ejection fraction and valve function, providing critical information to confirm the diagnosis of heart failure.
D) This choice is incorrect because a brain natriuretic peptide (BNP) level is a blood test that can aid in the diagnosis of CHF. Elevated BNP levels indicate heart strain, but it is not the gold standard for diagnosing CHF.
Explanation
A) This choice is incorrect because a narrowed mediastinum is not a characteristic finding in congestive heart failure. The mediastinum is the central region of the chest, and its width is not specifically related to CHF.
B) This choice is incorrect because hyperinflated lungs are a characteristic finding in chronic obstructive pulmonary disease (COPD), not congestive heart failure.
C) This choice is correct. Cardiomegaly, an enlarged heart, is a common finding in congestive heart failure. The heart may appear enlarged on a chest X-ray due to fluid accumulation and strain on the heart muscle.
D) This choice is incorrect because a normal cardiac silhouette on a chest X-ray would not be indicative of congestive heart failure. The presence of cardiomegaly is more suggestive of heart failure.
Explanation
A) This choice is incorrect because a complete blood count (CBC) is a general blood test that measures different components of the blood, such as red blood cells, white blood cells, and platelets. It is not specifically used to measure heart strain or diagnose CHF.
B) This choice is incorrect because a basic metabolic panel (BMP) is a blood test that measures electrolytes, kidney function, and glucose levels. It is not specific to diagnosing CHF.
C) This choice is correct. A brain natriuretic peptide (BNP) level is a blood test specifically used to measure heart strain. Elevated BNP levels can indicate heart failure, making it a valuable diagnostic tool in assessing suspected CHF.
D) This choice is incorrect because a C-reactive protein (CRP) level is a marker of inflammation and is not specific to diagnosing CHF.
Explanation
A) This choice is incorrect because a high-pitched, scratchy sound heard during inhalation is called a pleural friction rub and is associated with pleuritis or inflammation of the pleura, not congestive heart failure.
B) This choice is correct. An S3 heart sound is an extra heart sound heard immediately after S1 and S2, often described as a "ventricular gallop." It is associated with congestive heart failure and indicates increased fluid volume and strain on the ventricles.
C) This choice is incorrect because a prolonged, whooshing sound heard during systole is a heart murmur, which can be caused by various conditions, but it is not specific to the presence of an S3 sound.
D) This choice is incorrect because an irregular heart rhythm with varying intensity is characteristic of cardiac arrhythmias or irregular heartbeats and is not specific to the presence of an S3 sound.
Explanation
A) This choice is incorrect because serum electrolyte levels are not directly measured during an echocardiogram. They are typically assessed through a blood test and are not specific to evaluating heart function using ultrasound.
B) This choice is incorrect because blood pressure readings are not directly measured during an echocardiogram. Blood pressure is typically assessed using a sphygmomanometer and is not specific to evaluating heart function using ultrasound.
C) This choice is incorrect because oxygen saturation levels are not directly measured during an echocardiogram. Oxygen saturation is typically assessed using a pulse oximeter and is not specific to evaluating heart function using ultrasound.
D) This choice is correct. Ejection fraction (EF) is a parameter measured during an echocardiogram to assess the client's heart function. It represents the percentage of blood pumped out of the heart's left ventricle with each heartbeat and is an essential indicator of heart muscle efficiency and potential heart failure.
Questions
Explanation
A) This choice is incorrect because ACE inhibitors should not be taken with grapefruit juice. Grapefruit juice can interfere with the metabolism of the medication, leading to increased levels and potential side effects.
B) This choice is incorrect because the client should not adjust the dose of the ACE inhibitor without consulting their healthcare provider. Blood pressure should be monitored, but any dosage adjustments should be made by the healthcare provider based on the client's response to the medication.
C) This choice is correct. ACE inhibitors can cause a side effect of a persistent dry cough, and in some cases, difficulty breathing. The client should promptly report these symptoms to their healthcare provider for evaluation and possible adjustment of the medication regimen.
D) This choice is incorrect because while ACE inhibitors can increase potassium levels, avoiding foods high in potassium is not necessary unless specifically directed by the healthcare provider. The client should follow a balanced diet and inform the healthcare provider of any changes in their dietary habits.
Explanation
A) This choice is incorrect because loop diuretics can lead to increased sodium excretion, potentially causing hypernatremia (high sodium levels) rather than hyponatremia (low sodium levels).
B) This choice is incorrect because loop diuretics do not typically cause hypocalcemia (low calcium levels). They primarily affect sodium, potassium, and water excretion.
C) This choice is incorrect because loop diuretics are more likely to cause hypokalemia (low potassium levels) rather than hyperkalemia (high potassium levels). Loop diuretics can increase potassium excretion, leading to a potential deficiency.
D) This choice is correct. Loop diuretics are potent potassium-wasting diuretics, meaning they increase potassium excretion in the urine, potentially causing hypokalemia. The nurse should closely monitor the client's potassium levels and provide potassium supplementation if necessary.
Explanation
A) This choice is correct. Beta-blockers should not be abruptly discontinued, as sudden discontinuation can lead to rebound effects and worsen the client's condition. Gradual tapering of the medication is necessary under the guidance of the healthcare provider.

C) This choice is incorrect because limiting fluid intake is not specific to the administration of beta-blockers. Fluid intake may need to be adjusted based on the client's overall fluid balance and congestive heart failure status, but it is not a direct instruction related to the medication.
D) This choice is incorrect because the timing of beta-blocker administration varies depending on the specific beta-blocker prescribed and the client's individual response. Some beta-blockers may be taken in the morning, while others may be taken in the evening. The client should follow the prescribed schedule given by the healthcare provider.
Explanation
A) This choice is incorrect because bradycardia (slow heart rate) is not a common adverse effect of furosemide, a loop diuretic.
B) This choice is incorrect because hyperglycemia (high blood glucose levels) is not a common adverse effect of furosemide. In fact, furosemide can sometimes cause transient hypoglycemia.
C) This choice is correct. Hypotension (low blood pressure) is a potential adverse effect of furosemide due to its diuretic action. Furosemide causes the excretion of excess fluid, leading to a decrease in blood volume, which can result in hypotension.
D) This choice is incorrect because a dry, nonproductive cough is associated with ACE inhibitors, not furosemide.
Explanation
A) This choice is incorrect because while digoxin can impact liver function, it is not the primary parameter to be monitored. Liver function tests may be performed periodically to assess liver health during digoxin therapy.
B) This choice is incorrect because serum sodium levels are not directly impacted by digoxin. However, electrolyte imbalances, including hypokalemia, can potentiate digoxin toxicity, so potassium levels should be monitored.
C) This choice is correct. Digoxin is a cardiac glycoside that can impact renal function. Monitoring urine output is essential to assess kidney function and the client's response to the medication.
D) This choice is incorrect because blood glucose levels are not specifically impacted by digoxin. However, hypokalemia resulting from digoxin therapy can cause alterations in glucose metabolism, so blood glucose levels should be monitored in clients taking digoxin.

C) This choice is incorrect because the timing of spironolactone administration may vary depending on the client's individual response and the presence of other medications. The client should follow the prescribed schedule given by the healthcare provider.
D) This choice is incorrect because monitoring blood pressure daily and adjusting the dose accordingly is not specific to the administration of spironolactone. While blood pressure may need to be monitored regularly, dosage adjustments should only be made under the guidance of the healthcare provider.
Questions
Explanation
A) This choice is incorrect because consuming a diet high in sodium would exacerbate fluid retention in congestive heart failure. Clients with CHF should follow a low-sodium diet to reduce fluid overload and manage edema.
B) This choice is incorrect because limiting fluid intake to 1 liter per day is too restrictive and may lead to dehydration. Fluid restriction is essential for some clients with CHF, but the specific limit should be determined by the healthcare provider based on the client's individual needs.
C) This choice is incorrect because while potassium intake may need to be monitored, restricting potassium-rich foods is not a universal instruction for clients with CHF. It depends on the client's overall potassium levels and specific medication regimen.
D) This choice is correct. Following a low-sodium diet is essential for clients with congestive heart failure to reduce fluid retention and manage symptoms of fluid overload.
Explanation
A) This choice is incorrect because taking digoxin with a high-fat meal is not necessary. Digoxin can be taken with or without food, but consistent administration is essential for optimal therapeutic effects.
B) This choice is incorrect because skipping a dose of digoxin can lead to suboptimal medication levels and reduced effectiveness. If the client experiences nausea or vomiting, they should contact their healthcare provider for guidance.
C) This choice is correct. Digoxin is used to treat congestive heart failure and other cardiac conditions. It is crucial for clients to monitor their blood pressure regularly, especially if their healthcare provider has instructed them to adjust the medication dose based on their blood pressure readings.
D) This choice is incorrect because while avoiding certain over-the-counter medications is essential while on digoxin due to potential drug interactions, it is not the primary instruction for the client. The client should discuss any new medications, including over-the-counter drugs, with their healthcare provider to ensure they are safe to take with digoxin.
Explanation
A) This choice is incorrect because bradycardia (slow heart rate) is not a common adverse effect of furosemide, a loop diuretic.
B) This choice is correct. Furosemide is a loop diuretic that can lead to increased potassium excretion in the urine, potentially causing hypokalemia (low potassium levels). The nurse should closely monitor the client's potassium levels and provide potassium supplementation if necessary.
C) This choice is incorrect because hypertension (high blood pressure) is not typically associated with loop diuretics like furosemide. In fact, furosemide is used to treat hypertension and congestive heart failure by promoting the excretion of excess fluid and reducing blood pressure.
D) This choice is incorrect because hyperglycemia (high blood glucose levels) is not a common adverse effect of furosemide. In fact, furosemide can sometimes cause transient hypoglycemia.
Explanation
A) This choice is incorrect because limiting fluid intake to 1 liter per day is too restrictive and may lead to dehydration. Fluid restriction is essential for some clients with CHF, but the specific limit should be determined by the healthcare provider based on the client's individual needs.
B) This choice is incorrect because fluid restriction should not be limited to the evening only. Clients with CHF should monitor their fluid intake throughout the day to prevent fluid overload.
C) This choice is incorrect because drinking fluids primarily with meals may not be sufficient for managing fluid intake. Fluid intake should be balanced throughout the day to avoid excessive fluid retention.
D) This choice is correct. Monitoring daily weights is an essential strategy for clients with congestive heart failure to manage fluid balance. Sudden weight gain can indicate fluid retention, a common symptom of CHF. Clients should be instructed to report any significant weight changes to their healthcare provider promptly.
Explanation
A) This choice is incorrect because taking the nitrate medication with food is not necessary. Nitrate medications are usually taken sublingually or by mouth and are not associated with significant stomach upset.
B) This choice is correct. Nitrate medications, such as nitroglycerin, can cause a dangerous drop in blood pressure when used concurrently with erectile dysfunction medications, specifically phosphodiesterase type 5 inhibitors (PDE5 inhibitors) like sildenafil (Viagra) or tadalafil (Cialis). Clients should be warned against using these medications together to prevent hypotension and potential cardiovascular complications.
C) This choice is incorrect because grapefruit juice is not typically associated with nitrate medications. Grapefruit juice can interact with certain medications, but it is not a known interaction with nitrates.
D) This choice is incorrect because increasing the nitrate dose without healthcare provider guidance can be dangerous. Clients should be instructed to take nitrate medications as prescribed and seek immediate medical attention if chest pain is not relieved within a specific timeframe, as directed by their healthcare provider.
Questions
Myocardial Infarction (MI) and Angina Pectoris
Explanation
A) This choice is incorrect because obtaining a detailed health history is important, but administering aspirin is the priority action in a suspected MI. Aspirin helps to prevent further clot formation and reduces the risk of complications during a myocardial infarction.
B) This choice is correct. Administering aspirin as prescribed is the priority action in a suspected MI. Aspirin acts as an antiplatelet agent and can help to prevent the formation of blood clots that could exacerbate the blockage in the coronary artery.
C) This choice is incorrect because while performing a complete physical examination is important, administering aspirin takes precedence in a suspected MI to address the potential clot formation.
D) This choice is incorrect because placing the client in a supine position is not the priority action in a suspected MI. The client's position should be adjusted based on their comfort and ability to breathe effectively.
