The nurse is planning an educational program on sildenafil to a group of older male clients. Which of the following information should the nurse include in the educational program?

Consume a high-fat meal to increase the medication absorption.

Take the medication 2 hours prior to sexual activity.

Swallow the medication with grapefruit juice to improve the action.

Avoid ingestion of the medication with nitrates because it causes hypotension.

Answer and Explanation

The Correct Answer is D

Choice A reason: Consuming a high-fat meal does not increase the medication absorption, but rather delays it. A high-fat meal can reduce the peak plasma concentration and prolong the onset of action of sildenafil.

Choice B reason: Taking the medication 2 hours prior to sexual activity is not the optimal timing, as sildenafil has a half-life of about 4 hours and reaches its peak effect within 30 to 120 minutes. The recommended dose is 50 mg taken as needed, approximately 1 hour before sexual activity.

Choice C reason: Swallowing the medication with grapefruit juice does not improve the action, but rather inhibits it. Grapefruit juice can interfere with the metabolism of sildenafil and increase its plasma concentration and side effects.

Choice D reason: Avoiding ingestion of the medication with nitrates is the correct information, as it can cause a severe and potentially fatal drop in blood pressure. Nitrates are drugs used to treat angina and heart failure, and they can interact with sildenafil to cause vasodilation and hypotension.

Correct Answer is C

Explanation

Choice A reason: This is incorrect because lispro insulin is a rapid-acting insulin that does not need to be administered with another type of insulin. However, the patient may need a long-acting or intermediate-acting insulin to provide basal coverage throughout the day.

Choice B reason: This is incorrect because lispro insulin has a peak action of 30 to 90 min after the injection, which means that the patient is at the highest risk of hypoglycemia during this time. The nurse should assess for hypoglycemia more frequently than 4 hr after the injection.

Choice C reason: This is correct because lispro insulin has a fast onset of action of 15 to 30 min after the injection, which means that the patient should eat a meal within 15 min of the injection to prevent hypoglycemia.

Choice D reason: This is incorrect because polyuria is a sign of hyperglycemia, not hypoglycemia. The nurse should monitor for polyuria before the insulin injection, as it may indicate that the patient's blood glucose level is high.

A. Inject 20 units of air into the NPH insulin vial. B. Inject 10 units of air into the regular insulin vial. C. Replace the needle for withdrawal with a safety needle. D. Withdraw 10 units of insulin from the regular insulin vial.

Correct Answer is B

Explanation

Choice A reason: This is incorrect because the nurse should inject air into the NPH insulin vial after injecting air into the regular insulin vial. This prevents contamination of the regular insulin with the NPH insulin.

Choice B reason: This is correct because the nurse should inject air into the regular insulin vial first, then into the NPH insulin vial, before withdrawing the regular insulin. This equalizes the pressure in the vials and facilitates the withdrawal of the insulin.

Choice C reason: This is incorrect because the nurse should not replace the needle for withdrawal with a safety needle. The same needle should be used for injecting air and withdrawing insulin from both vials.

Choice D reason: This is incorrect because the nurse should withdraw 10 units of insulin from the regular insulin vial after injecting air into both vials. This prevents mixing of the NPH insulin with the regular insulin in the vial.
