What nursing assessments/interventions should be completed prior to administering Isotonic IV solutions? (Select all that apply)
Elevate the head of the bed to 35-45 degrees unless contraindicated
Assess Vital Signs
Recheck MD orders post infusion
Assess lung and heart sounds
Obtain baseline weight
Review labs post infusion
Correct Answer : A,B,D,E
Choice A rationale:
Elevate the head of the bed to 35-45 degrees unless contraindicated:
Promotes venous return: Elevating the head of the bed reduces venous pooling in the lower extremities and promotes venous return to the heart. This helps to improve cardiac output and reduce the risk of fluid overload.
Reduces aspiration risk: Elevating the head of the bed also helps to prevent aspiration, as it keeps the head and neck in a more upright position. This allows for better drainage of secretions and reduces the chance of them entering the lungs.
Contraindications: There are a few contraindications to elevating the head of the bed, such as severe hypotension, head injury, or spinal injury. In these cases, the potential benefits of elevation must be weighed against the risks.
Choice B rationale:
Assess Vital Signs:
Baseline assessment: It's crucial to obtain baseline vital signs before administering any IV fluid to have a reference point for comparison. This allows for early detection of any changes that may indicate fluid overload or other complications.
Monitoring fluid status: Vital signs, including blood pressure, heart rate, respiratory rate, and temperature, provide important information about the patient's fluid status and hemodynamic stability. Changes in vital signs can signal fluid overload, dehydration, or other problems that may require intervention.
Detecting adverse reactions: Vital signs can also help to detect adverse reactions to the IV fluid, such as allergic reactions or anaphylaxis. Early identification of these reactions is essential for prompt treatment.
Choice D rationale:
Assess lung and heart sounds:
Baseline assessment: Assessing lung and heart sounds before IV fluid administration provides a baseline for comparison and helps to identify any preexisting conditions that may affect fluid tolerance.
Detecting fluid overload: Crackles in the lungs, increased heart rate, and extra heart sounds can indicate fluid overload, which can lead to pulmonary edema and heart failure.
Monitoring response to therapy: Lung and heart sounds can also be used to monitor the patient's response to IV fluid therapy. Improvement in lung sounds and heart rate can indicate a positive response to treatment.
Choice E rationale:
Obtain baseline weight:
Accurate fluid balance: Obtaining a baseline weight is essential for accurate assessment of fluid balance. It allows for tracking of fluid gains and losses and helps to prevent fluid overload or dehydration.
Monitoring fluid status: Changes in weight can reflect changes in fluid status. Weight gain can indicate fluid retention, while weight loss can suggest dehydration.

Correct Answer is B
Explanation
Choice B rationale:
Benign tumors typically grow in the wrong place or at the wrong time. This is a key distinguishing feature of benign tumors compared to normal cells. Normal cells have precise mechanisms that control their growth, ensuring they divide and multiply only when and where they are needed. Benign tumors, however, have disruptions in these regulatory mechanisms, leading to abnormal growth patterns. This means they may grow in locations where they don't belong or continue to grow even when they are no longer needed.
Here's a detailed explanation of why the other choices are incorrect:
Choice A:
Benign tumors have not lost their cellular regulation from contact inhibition. Contact inhibition is a process that stops normal cells from growing when they come into contact with other cells. Benign tumors still maintain this ability, which helps to limit their growth and prevent them from spreading to other tissues.
Choice C:
Benign tumors do not grow through invasion of other tissue. Invasion is a hallmark feature of malignant tumors (cancers). Benign tumors, on the other hand, typically grow as encapsulated masses, meaning they are surrounded by a well-defined border that separates them from surrounding tissues. They do not infiltrate or invade surrounding structures.
Choice D:
Anaplasia refers to the loss of differentiation and resemblance to the parent cells, which is a characteristic of malignant tumors, not benign tumors. Benign tumors still maintain a degree of differentiation, meaning they retain some of the characteristics of the normal cells from which they originated.
Correct Answer is A
Explanation
Choice A rationale:
Hyperventilation is a condition characterized by rapid and deep breathing, leading to excessive removal of carbon dioxide (CO2) from the body. This decrease in CO2 levels actually causes respiratory alkalosis, not respiratory acidosis.
CO2 is a weak acid, and its removal from the blood raises the blood pH, making it more alkaline. Key mechanisms involved in hyperventilation-induced respiratory alkalosis:
Increased alveolar ventilation: Hyperventilation increases the rate at which CO2 is expelled from the lungs, reducing its concentration in the blood.
Shift in the equilibrium of the carbonic acid-bicarbonate buffer system: The reduction in CO2 levels drives the equilibrium towards the formation of bicarbonate ions, further reducing the concentration of hydrogen ions and increasing pH.
Renal compensation: The kidneys respond to respiratory alkalosis by excreting more bicarbonate ions, which helps to normalize the blood pH.
Choice B rationale:
Asthma is a chronic respiratory disease characterized by inflammation and narrowing of the airways. This can lead to impaired ventilation and retention of CO2, which can contribute to respiratory acidosis.
Mechanisms by which asthma can cause respiratory acidosis:
Bronchoconstriction: Narrowed airways impede airflow, making it difficult to expel CO2 from the lungs.
Air trapping: Inflammation and mucus production can lead to air becoming trapped in the lungs, further increasing CO2 levels.
Hypoventilation: Severe asthma attacks can cause respiratory muscle fatigue, leading to a decrease in breathing rate and inadequate CO2 removal.
Choice C rationale:
Chronic obstructive pulmonary disease (COPD) is a group of lung diseases characterized by chronic obstruction of airflow. This obstruction can lead to impaired ventilation and retention of CO2, which can contribute to respiratory acidosis.
Mechanisms by which COPD can cause respiratory acidosis:
Emphysema: Destruction of lung tissue reduces the surface area available for gas exchange, making it difficult to expel CO2. Chronic bronchitis: Inflammation and mucus production in the airways can obstruct airflow and trap CO2 in the lungs.
Hypoventilation: COPD can lead to respiratory muscle fatigue and a decrease in breathing rate, further impairing CO2 removal.
Choice D rationale:
Pulmonary embolism (PE) is a blockage of an artery in the lungs, usually by a blood clot. This can lead to impaired gas exchange and a decrease in oxygen levels in the blood. In severe cases, PE can also cause respiratory acidosis due to inadequate CO2 removal.
Mechanisms by which PE can cause respiratory acidosis:
Ventilation-perfusion mismatch: PE obstructs blood flow to a portion of the lungs, reducing the amount of CO2 that can be removed from those areas.
Hypoxemia: Low oxygen levels in the blood can stimulate the respiratory drive, leading to hyperventilation and CO2 retention.
Right heart failure: PE can strain the right side of the heart, leading to decreased pulmonary blood flow and impaired CO2 removal.
