Nursing Elites

1. A client with cirrhosis is at risk for bleeding due to impaired liver function. Which laboratory result is the most important to monitor?

• A. Blood urea nitrogen (BUN)
• B. Prothrombin time (PT)
• C. Aspartate aminotransferase (AST)
• D. Serum albumin

Correct answer: B

Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

2. A client with hyperparathyroidism is preparing for surgery. Which preoperative lab finding is most important to report?

• A. Elevated serum calcium.
• B. Decreased serum albumin.
• C. Elevated serum potassium.
• D. Elevated serum magnesium.

Correct answer: A

Rationale: The correct answer is A: Elevated serum calcium. In hyperparathyroidism, elevated calcium levels can lead to complications such as kidney stones, bone pain, and fractures. During surgery, high calcium levels can affect neuromuscular function, cardiac function, and blood clotting. Therefore, it is crucial to report elevated serum calcium levels preoperatively to prevent potential surgical complications. Choices B, C, and D are not directly associated with hyperparathyroidism and are less likely to impact the surgical outcome in this scenario.

3. After receiving hemodialysis, what is the nurse's priority assessment for a client with chronic kidney disease?

• A. Monitor the client's potassium level.
• B. Assess the client's blood pressure.
• C. Check the client's hemoglobin and hematocrit levels.
• D. Monitor for signs of infection.

Correct answer: A

Rationale: The correct answer is to monitor the client's potassium level. During hemodialysis, there is a risk of potassium shifting, which can lead to life-threatening arrhythmias if not properly managed. Assessing the potassium level is crucial to prevent complications. While assessing blood pressure, checking hemoglobin and hematocrit levels, and monitoring for signs of infection are important aspects of care for a client with chronic kidney disease, monitoring potassium levels takes precedence due to its immediate life-threatening potential post-dialysis.

4. The nurse is preparing to administer a blood transfusion to a client. Which action is most important for the nurse to take before starting the transfusion?

• A. Administer pre-transfusion medication
• B. Ensure the client has an adequate fluid intake
• C. Monitor the client's vital signs
• D. Verify the blood type with another nurse

Correct answer: D

Rationale: Verifying the blood type with another nurse is critical before starting a blood transfusion to prevent a potentially life-threatening transfusion reaction. This step ensures that the client receives the correct blood product. Administering pre-transfusion medication, ensuring adequate fluid intake, and monitoring vital signs are important steps during the transfusion process, but verifying the blood type is the most crucial step to ensure patient safety.

5. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.
