Nursing Elites

1. The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?

• A. Blood glucose
• B. Serum sodium
• C. Serum potassium
• D. Blood urea nitrogen (BUN)

Correct answer: C

Rationale: The correct answer is C: Serum potassium. When a client is receiving furosemide, a loop diuretic, it can lead to potassium loss. Monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias. Blood glucose (Choice A) is not directly impacted by furosemide. Serum sodium (Choice B) may be affected, but monitoring potassium is more critical due to the risk of arrhythmias. Blood urea nitrogen (BUN) (Choice D) is important for assessing kidney function but is not the most crucial value to monitor in a client taking furosemide.

2. A client with a history of coronary artery disease (CAD) is prescribed simvastatin (Zocor). The nurse should teach the client about which potential side effect?

• A. Muscle pain
• B. Dry mouth
• C. Drowsiness
• D. Diarrhea

Correct answer: A

Rationale: Muscle pain is a common side effect of statins like simvastatin and can indicate a serious condition called rhabdomyolysis. Rhabdomyolysis is a severe condition where muscle fibers break down rapidly, releasing myoglobin into the bloodstream, which can lead to kidney damage. Therefore, it's important for the nurse to educate the client about this potential side effect and to promptly report any muscle pain to the healthcare provider. Dry mouth, drowsiness, and diarrhea are not commonly associated with simvastatin use and are less concerning compared to the risk of rhabdomyolysis.

3. A client has a new prescription for propranolol. Which of the following instructions should be included?

• A. Take the medication with food.
• B. Monitor heart rate daily.
• C. Increase intake of potassium-rich foods.
• D. Avoid consuming dairy products.

Correct answer: B

Rationale: The correct answer is to monitor heart rate daily. Propranolol is a beta-blocker that can lower heart rate and blood pressure, so it is essential to monitor heart rate regularly to detect any signs of bradycardia, a potential side effect of the medication. Choice A is incorrect because propranolol can be taken with or without food. Choice C is incorrect as increasing potassium-rich foods is not specifically required with propranolol. Choice D is also incorrect as there is no need to avoid consuming dairy products with propranolol.

4. The client admitted to the hospital with pulmonary edema is preparing for discharge. The client should be reminded of the importance of complying with which measure to prevent a recurrence?

• A. Weigh oneself every morning before breakfast.
• B. Sleep with the head elevated on multiple pillows.
• C. Adjust diuretic dose without healthcare provider guidance.
• D. Take additional digoxin (Lanoxin) as a preventive measure.

Correct answer: A

Rationale: Monitoring weight daily, especially in the morning before breakfast, is crucial in detecting fluid retention early and preventing pulmonary edema. Sudden weight gain can indicate fluid accumulation, prompting timely intervention to prevent complications. Choice A is the correct answer because daily weight monitoring is a key component in managing heart failure and preventing pulmonary edema recurrence. Choices B and D are not directly related to preventing fluid retention or pulmonary edema recurrence. Choice C is unsafe as adjusting diuretic doses without healthcare provider guidance can lead to electrolyte imbalances and worsening of the condition.

5. A client's serum calcium level is 7.9 mg/dL. The nurse is immediately concerned, knowing that this level could lead to which complication?

• A. Stroke
• B. Cardiac arrest
• C. High blood pressure
• D. Urinary stone formation

Correct answer: B

Rationale: A serum calcium level below normal (hypocalcemia) can lead to cardiac arrhythmias and potentially cardiac arrest. Calcium plays a crucial role in cardiac muscle contractility, and low levels can disrupt normal heart function, potentially leading to fatal arrhythmias and cardiac arrest. Choices A, C, and D are incorrect as hypocalcemia is not directly associated with stroke, high blood pressure, or urinary stone formation. The immediate concern with low serum calcium levels is the risk of cardiac complications.
