Rationale:

A. This is the most critical and first-line priority in managing DIC. DIC is not a primary disease but a complication of conditions such as sepsis, trauma, malignancy, or obstetric emergencies (e.g., placental abruption). The widespread activation of the clotting cascade will continue unless the trigger is removed. For example, administering antibiotics for sepsis or delivering the placenta in obstetric cases directly addresses the root cause. Without this step, supportive treatments alone will be ineffective.

B. Beta blockers are used to manage conditions such as hypertension, arrhythmias, or heart failure. They have no role in correcting the coagulation abnormalities seen in DIC. They do not affect platelet consumption, clotting factor depletion, or fibrinolysis. Therefore, this option is inappropriate and incorrect.

C. Although it may seem counterintuitive in a condition associated with bleeding, heparin can be used in selected cases of DIC, particularly when thrombotic manifestations predominate (e.g., digital ischemia, organ dysfunction from microthrombi, or chronic DIC). Heparin works by inhibiting further clot formation, thereby reducing consumption of clotting factors and platelets. However, it is used cautiously and is generally avoided in patients with severe active bleeding. This makes it a situational but appropriate intervention.

D. Patients with DIC are at high risk for hypovolemia and shock due to bleeding and capillary leakage. Isotonic fluids like lactated Ringer’s help maintain intravascular volume, blood pressure, and organ perfusion. Adequate fluid resuscitation is essential to prevent complications such as acute kidney injury and multi-organ failure. This is a key supportive therapy.

E. In DIC, clotting factors are rapidly consumed, leading to coagulopathy and bleeding. FFP contains all clotting factors and is administered to replace depleted factors, correct prolonged PT/INR and aPTT, and help control bleeding. It is especially indicated in patients with active bleeding or those at high risk for bleeding.

Rationale:

A. Hyperparathyroidism, whether primary (due to parathyroid adenoma, hyperplasia, or carcinoma) or secondary (commonly related to chronic kidney disease), does not resolve spontaneously. Without appropriate management, persistent elevated parathyroid hormone (PTH) levels can lead to chronic hypercalcemia, kidney stones, bone demineralization (osteopenia/osteoporosis), and cardiovascular complications. Telling the patient it will resolve on its own is misleading and can delay necessary interventions.

B. Adequate hydration is a primary preventive measure in hyperparathyroidism. High calcium levels increase renal calcium excretion but can also promote calcium stone formation if fluid intake is insufficient. Drinking 2–3 liters of water daily, unless contraindicated, helps dilute urinary calcium and reduce the risk of kidney stones. Hydration also helps prevent the dehydration that often accompanies hypercalcemia due to polyuria.

C. Hypercalcemia can cause polyuria, nausea, vomiting, and weakness, all of which increase the risk of dehydration. The nurse should assess skin turgor, mucous membranes, blood pressure, heart rate, and daily weight to detect fluid loss early. Timely detection allows for prompt interventions such as oral or IV fluid replacement, reducing complications such as hypotension or acute kidney injury.

D. Laboratory monitoring is essential for tracking disease progression and evaluating treatment effectiveness. Key labs include serum calcium, phosphate, PTH, creatinine, and 25-hydroxy vitamin D levels. Frequent monitoring allows clinicians to adjust interventions, such as recommending surgery or pharmacologic treatment (e.g., bisphosphonates or calcimimetics), before severe complications occur.

E. These foods are high in calcium, which can exacerbate hypercalcemia in patients with hyperparathyroidism. Dietary calcium restriction is often advised to prevent further elevation of serum calcium levels, although strict restriction is usually balanced with maintaining adequate calcium for bone health.

F. Calcium supplements are generally avoided in hyperparathyroidism unless the patient has undergone parathyroidectomy and is at risk for hypocalcemia. Unmonitored supplementation can worsen hypercalcemia and increase the risk of kidney stones and cardiovascular complications.

G. In primary hyperparathyroidism, PTH increases calcium reabsorption and phosphate excretion, leading to hypophosphatemia. Encouraging foods higher in phosphorus (e.g., meat, poultry, fish, eggs, and some whole grains) can help balance calcium-phosphate levels, reduce hypercalcemia complications, and support bone health.

H. While high-impact activity or excessive strain should be avoided due to bone fragility, complete inactivity is not recommended. Moderate weight-bearing exercise helps maintain bone density, prevent muscle loss, and support overall cardiovascular health. Limiting all activity could worsen osteopenia, muscle weakness, and functional decline.

Rationale:

A. Ibuprofen should not be redosed this quickly. The typical dosing interval is every 6–8 hours, depending on the formulation. Taking an additional dose too soon increases the risk of gastrointestinal, renal, and cardiovascular adverse effects.

B. Combining NSAIDs (e.g., ibuprofen with naproxen or aspirin) increases the risk of GI bleeding, kidney injury, and other adverse effects. NSAIDs should not be combined unless specifically directed by a healthcare provider.

C. Ibuprofen is an NSAID, which can irritate the stomach lining and increase the risk of gastritis or ulcers. Taking it with food, milk, or antacids helps reduce GI irritation.

D. Acetaminophen is not an NSAID and does not affect platelet function or the GI mucosa. It is generally safer for patients at risk of GI bleeding or those who require normal coagulation.

E. Incorrect for typical adult dosing. The maximum recommended daily dose for healthy adults is 3,000–4,000 mg, depending on guidelines and liver function. 1,200 mg is usually a limit for over-the-counter preparations or special populations, but education should reflect safe adult dosing and emphasize not exceeding the recommended maximum.

F. NSAIDs like ibuprofen can cause GI bleeding, so patients should be instructed to report symptoms such as dark/tarry stools, vomiting blood, or abdominal pain.

Rationale:
A. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can inhibit platelet function and increase bleeding risk. In children with hemophilia, NSAIDs should be avoided for pain management. Acetaminophen is preferred for mild to moderate pain.

B. Monitoring vital signs helps detect early signs of internal bleeding, such as tachycardia or hypotension. Observing the progression of bruising and joint swelling is essential to assess bleeding severity and prevent complications like hemarthrosis or joint damage.

C. Children with hemophilia are at high risk for bleeding with trauma or falls. Activity should be encouraged with appropriate protective gear, supervision, and avoidance of high-impact sports to prevent injuries.

D. Administration of the specific clotting factor (Factor VIII or IX, depending on type) is the primary treatment for preventing or controlling bleeding episodes in hemophilia. Early replacement can reduce joint damage and manage pain associated with hemarthrosis.

Rationale:
A. NSAIDs can increase the risk of methotrexate toxicity by reducing renal clearance, which may lead to dangerous accumulation and increased risk of liver or bone marrow toxicity. Clients are advised to consult their provider before taking any over-the-counter medications.

B. Methotrexate inhibits folate metabolism, which is why folic acid supplementation is often prescribed. However, dietary folate alone is insufficient to prevent toxicity, and clients should follow prescribed folic acid supplementation rather than relying solely on diet.

C. Some vitamins and supplements, especially those containing high doses of folic acid, iron, or other interacting compounds, may interfere with methotrexate’s effectiveness or toxicity profile. Clients should confirm all supplements with their provider.

D. Methotrexate can cause hepatotoxicity, and alcohol consumption further increases this risk. Avoiding alcohol is a key teaching point to minimize liver damage while on therapy.

Rationale:

A. This question assesses the Radiation component of PQRST. It helps determine if the pain spreads from its origin to other areas, which can assist in diagnosing the underlying cause (e.g., cardiac, neurological, or musculoskeletal). However, it does not provide information about what triggers or worsens the pain, so it does not assess precipitating factors.

B. This question addresses the impact of pain on function and quality of life. It helps the nurse understand how pain interferes with self-care, school, work, or social activities. While important for holistic care and planning interventions, it does not identify triggers, aggravating factors, or causes of pain.

C. This question directly assesses Provocation/Palliation, which identifies factors that trigger, exacerbate, or relieve pain. For example, certain movements, positions, environmental stimuli, or medications may worsen or improve pain. Knowing these details allows the nurse to recommend activity modifications, preventative strategies, and individualized interventions to manage pain effectively.

D. This evaluates the Quality of pain, providing information about its nature, such as whether it is neuropathic, musculoskeletal, or inflammatory. While this is essential for diagnostic purposes, it does not provide insight into what precipitates or alleviates the pain, which is the focus of Provocation.

E. This explores Related Symptoms, which may indicate the underlying condition causing the pain (e.g., nausea with migraine, numbness with neuropathy). It is valuable for diagnosis but does not assess triggers or provoking factors.

F. This question assesses Provocation by identifying the activity, event, or situation that initiated the pain. For example, the pain may occur after physical activity, certain movements, eating specific foods, or exposure to stress. Understanding this helps the nurse implement preventive strategies, adjust activity recommendations, and plan interventions to reduce future episodes.

Rationale:

A. This is a critical safety step. The nurse must verify the right patient, blood type, Rh factor, unit number, and expiration date with another qualified professional. This helps prevent life-threatening transfusion reactions, making this correct.

B. A 24-gauge catheter is too small for safe blood transfusion in most cases, especially for adults. Blood is typically administered through a larger bore IV (18–20 gauge) to prevent hemolysis and allow adequate flow. Therefore, this is incorrect.

C. This is one of the most essential steps in preventing hemolytic transfusion reactions, which can be fatal. Proper compatibility verification is mandatory before starting the transfusion. Therefore, this is correct.

D. The nurse must assess IV patency and site condition before initiating the transfusion. Starting without checking may result in infiltration or complications. This is unsafe and incorrect.

E. Blood should only be administered with 0.9% normal saline. Dextrose-containing solutions can cause hemolysis or clotting of blood products. Therefore, this is incorrect.

F. Informed consent is a legal and ethical requirement before administering blood products. The nurse must ensure that consent has been obtained and documented. Therefore, this is correct.

Rationale:

A. Rheumatoid arthritis (RA) can limit a patient’s ability to perform ADLs due to joint pain, stiffness, and reduced grip strength. Providing assistive devices such as adaptive utensils, dressing aids, or jar openers allows the patient to maintain independence, safety, and functional ability, which is the nurse’s priority.

B. While range of motion exercises are important for long-term joint mobility and preventing contractures, they are not the immediate intervention to help the patient perform ADLs safely and independently. Exercise can be introduced once basic functional needs are supported.

C. Pain management may be part of care, but over-the-counter medications may be insufficient or unsafe depending on the patient’s condition and medications. This does not directly address the functional limitation in performing ADLs.

D. Complete rest can lead to muscle atrophy, joint stiffness, and decreased independence, which may worsen functional impairment. RA management balances rest and gentle activity, but avoiding all movement is not recommended.

Rationale:

A. These are common side effects of opioid use, not withdrawal. During withdrawal, gastrointestinal motility increases and alertness rises, leading to diarrhea, insomnia, and agitation rather than constipation and drowsiness.

B. While mild autonomic changes can occur, hypotension is not a hallmark of opioid withdrawal. Hyperactivity may be present in terms of restlessness, but this option does not capture the key constellation of withdrawal symptoms.

C. These are classic opioid withdrawal symptoms. Rhinitis (runny nose), yawning, lacrimation, abdominal cramping, diarrhea, restlessness, and agitation are signs of the sympathetic nervous system overactivity that occurs when opioids are abruptly discontinued or doses are missed. These symptoms guide nursing monitoring and support.

D. These are common effects of opioid overdose, not withdrawal. Withdrawal typically causes tachycardia, hypertension, and increased respiratory rate, reflecting sympathetic activation

Rationale:

A. Using the same tubing may allow residual blood to continue entering the patient, which could worsen the reaction. Proper procedure requires new tubing to safely infuse saline.

B. Although notifying the provider and documenting are important, the priority is to stop the transfusion immediately to prevent further exposure and reduce risk of life-threatening complications.

C. Stopping the transfusion prevents further exposure to the incompatible blood product. Maintaining IV access with saline through new tubing allows for hydration, administration of emergency medications if needed, and collection of samples for evaluation, ensuring patient safety.

D. During a transfusion reaction, vital signs should be monitored continuously, not every 30 minutes, to promptly detect rapid changes such as hypotension, tachycardia, or respiratory distress. Continuous assessment is essential to intervene immediately if the patient’s condition deteriorates.
