Nursing Elites

1. 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.

2. Where should the healthcare provider consider starting a screening program for hypothyroidism?

• A. A business and professional women’s group.
• B. An African-American senior citizens' center.
• C. A daycare center in a Hispanic neighborhood.
• D. An after-school center for Native American teens.

Correct answer: B

Rationale: An African-American senior citizens' center is the most appropriate location to start a screening program for hypothyroidism. Older adults are at an increased risk of hypothyroidism, and African-Americans are more likely to be underserved in healthcare. Therefore, targeting this group can help in early detection and management of hypothyroidism. The other options, such as a business and professional women’s group, a daycare center in a Hispanic neighborhood, and an after-school center for Native American teens, do not align as closely with the demographic at higher risk for hypothyroidism.

3. What instruction should the nurse include for a client prescribed nitroglycerin for a myocardial infarction?

• A. Take the medication only when experiencing severe chest pain.
• B. Store the medication in a dark container to protect it from light.
• C. Take the medication before engaging in physical activity that may trigger chest pain.
• D. Limit nitroglycerin use to no more than three doses in 15 minutes.

Correct answer: D

Rationale: The correct answer is D: 'Limit nitroglycerin use to no more than three doses in 15 minutes.' This instruction is crucial to prevent excessive use, which can lead to severe hypotension and other complications. Choice A is incorrect because nitroglycerin should also be used preventatively, not only during severe chest pain. Choice B is irrelevant and not a necessary instruction for nitroglycerin use. Choice C is incorrect as nitroglycerin is typically taken to prevent chest pain rather than waiting for an activity that may trigger it.

4. The nurse is caring for a client in atrial fibrillation. The atrial heart rate is 250, and the ventricular rate is controlled at 75. Which of the following findings is cause for the most concern?

• A. Diminished bowel sounds
• B. Loss of appetite
• C. A cold, pale lower leg
• D. Tachypnea

Correct answer: C

Rationale: A cold, pale lower leg is cause for the most concern as it could indicate compromised blood circulation, potentially leading to serious complications like ischemia or thrombosis. Diminished bowel sounds, loss of appetite, and tachypnea are not directly related to the client's condition in atrial fibrillation and the heart rate discrepancy.

5. Which documentation indicates that activities to prevent postoperative venous stasis were performed correctly?

• A. Antiembolism stockings on, leg exercises performed hourly.
• B. Antiembolism stockings removed hourly during leg exercises.
• C. Leg exercises not performed due to antiembolism hose.
• D. Client demonstrates ability to move extremities well.

Correct answer: A

Rationale: The correct answer is A: 'Antiembolism stockings on, leg exercises performed hourly.' This documentation indicates the correct performance of activities to prevent postoperative venous stasis, as both components are crucial for prevention. Choice B is incorrect because removing stockings hourly is not recommended. Choice C is incorrect as leg exercises should be performed despite wearing antiembolism stockings. Choice D is incorrect as demonstrating the ability to move extremities well does not specifically address the prevention of venous stasis.
