Nursing Elites

1. 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.

2. A client with hypertension is prescribed hydrochlorothiazide. What teaching should the nurse provide?

• A. Take the medication in the morning to avoid frequent urination at night.
• B. Increase fluid intake to prevent dehydration.
• C. Avoid potassium-rich foods, such as bananas and oranges.
• D. Monitor the client’s potassium levels weekly.

Correct answer: B

Rationale: The correct teaching for a client prescribed hydrochlorothiazide is to increase fluid intake to prevent dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and electrolyte imbalances, so adequate fluid intake is crucial. Choice A is incorrect because hydrochlorothiazide is typically taken in the morning to avoid nighttime urination. Choice C is incorrect as potassium-rich foods should not be avoided but monitored, as hydrochlorothiazide can cause potassium loss. Choice D is incorrect as potassium levels should be monitored regularly, but not necessarily weekly, unless indicated by the healthcare provider.

3. 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.

4. A client with Alzheimer's disease is prescribed donepezil. What is the most important teaching point?

• A. Take the medication as directed for best results.
• B. Report any unusual changes in behavior.
• C. This medication helps improve cognitive function.
• D. This medication is not a cure for Alzheimer's disease.

Correct answer: C

Rationale: The most important teaching point for a client prescribed donepezil is that it helps improve cognitive function. While it is important to take the medication as directed for best results (choice A) and report any unusual changes in behavior (choice B), the key point is that donepezil is not a cure for Alzheimer's disease (choice D). Therefore, the correct answer is C.

5. A client with heart failure has a prescription for digoxin. The nurse is aware that sufficient potassium should be included in the diet because hypokalemia in combination with this medication ____________.

• A. Can predispose to dysrhythmias
• B. May lead to oliguria
• C. May cause irritability and anxiety
• D. Sometimes alters consciousness

Correct answer: A

Rationale: The correct answer is A: Can predispose to dysrhythmias. Hypokalemia combined with digoxin increases the risk of dysrhythmias due to the potentiation of digoxin's effects on cardiac conduction. Choice B, May lead to oliguria, is incorrect because hypokalemia is not typically associated with oliguria. Choice C, May cause irritability and anxiety, is incorrect as these symptoms are more commonly associated with hypocalcemia. Choice D, Sometimes alters consciousness, is incorrect as altered consciousness is not a typical effect of hypokalemia combined with digoxin.
