Nursing Elites

1. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

2. A client who has been prescribed multiple antihypertensive medications experiences syncope and has a blood pressure of 70/40. What is the rationale for the nurse to hold the next scheduled antihypertensive dose?

• A. Increased urinary clearance of the medications has produced diuresis, lowering the blood pressure.
• B. The antagonistic interaction of the medications has reduced their effectiveness.
• C. The synergistic effect of the medications has resulted in drug toxicity, causing hypotension.
• D. The additive effect of the medications has lowered the blood pressure too much.

Correct answer: D

Rationale: The additive effect of multiple antihypertensive medications can cause hypotension, leading to dangerously low blood pressure. In this scenario, the client experiencing syncope with a blood pressure of 70/40 indicates severe hypotension, likely due to the combined action of the antihypertensive medications. Holding the next scheduled dose is essential to prevent further lowering of blood pressure and potential complications. Choices A, B, and C provide inaccurate explanations and do not align with the client's presentation and the need to manage hypotension caused by the additive effect of the medications.

3. The nurse is teaching a group of clients about managing diabetes. Which of the following should be emphasized as a goal for all diabetics?

• A. Frequent exercise and weight control
• B. Prevent eye damage
• C. Keep insulin refrigerated at all times
• D. Prevent the development of complications

Correct answer: A

Rationale: The correct answer is A: Frequent exercise and weight control. These should be emphasized as a goal for all diabetics because they help prevent complications and manage blood sugar levels. Regular physical activity and maintaining a healthy weight are crucial in managing diabetes as they can improve insulin sensitivity, regulate blood sugar levels, and reduce the risk of cardiovascular complications. Choice B, preventing eye damage, is important but is more specific to diabetic retinopathy and not a general goal for all diabetics. Choice C, keeping insulin refrigerated, is essential for insulin storage but not a primary goal for all diabetics. Choice D, preventing the development of complications, is too broad and does not provide a specific actionable goal for all diabetics.

4. Before administering digoxin to a client with heart failure, what is the most important assessment for the nurse to perform?

• A. Check the client's blood pressure
• B. Monitor the client's heart rate
• C. Assess the client's respiratory rate
• D. Review the client's potassium level

Correct answer: B

Rationale: The correct answer is to monitor the client's heart rate. Digoxin slows the heart rate, so it is crucial to assess the heart rate before administering the medication. If the heart rate is below 60 beats per minute, the dose should be held, and the healthcare provider should be notified. Checking the blood pressure (Choice A) is important but not as crucial as monitoring the heart rate in this case. Assessing the respiratory rate (Choice C) is not directly related to the action of digoxin. Reviewing the client's potassium level (Choice D) is important for clients taking digoxin due to the risk of hypokalemia, but assessing the heart rate takes priority.

5. The nurse is caring for a client with a traumatic brain injury who is receiving mechanical ventilation. Which assessment finding indicates that the client may be experiencing increased intracranial pressure (ICP)?

• A. Client becomes increasingly lethargic
• B. Client's respiratory rate is 16 breaths per minute
• C. Client responds to verbal stimuli
• D. Client's pupils are equal and reactive

Correct answer: A

Rationale: Increased lethargy is a sign of worsening intracranial pressure, which can be life-threatening in clients with brain injuries. As ICP rises, it can lead to decreased level of consciousness, such as lethargy or even coma. Choices B, C, and D are not indicative of increased ICP. A normal respiratory rate, response to verbal stimuli, and equal reactive pupils do not specifically point towards increased intracranial pressure.
