During the administration of finasteride, the nurse must remember which important precaution?
The patient needs to be warned that alopecia is a common adverse effect.
It is given by deep intramuscular injection to avoid tissue irritation.
It must not be handled by pregnant women.
It must be taken on an empty stomach.
The Correct Answer is C
Choice A reason: This is incorrect because alopecia is not a common or serious adverse effect of finasteride. However, the patient should be informed that finasteride may cause decreased hair growth or loss of hair in some cases.
Choice B reason: This is incorrect because finasteride is not given by injection, but by oral route. The patient should take one tablet daily with or without food.
Choice C reason: This is correct because finasteride can cause birth defects in male fetuses if it is absorbed through the skin or ingested by pregnant women. The patient should wear gloves when handling the tablets and avoid contact with crushed or broken tablets.
Choice D reason: This is incorrect because finasteride can be taken with or without food. However, the patient should take it at the same time each day and follow the provider's instructions.

Correct Answer is D
Explanation
Choice A reason: This is incorrect because sildenafil and nitrates do not affect each other's effectiveness, but rather their side effects. Sildenafil is a phosphodiesterase-5 inhibitor that enhances the effect of nitric oxide, which causes vasodilation and increases blood flow to the penis. Nitrates are vasodilators that also increase nitric oxide levels and reduce the workload of the heart.
Choice B reason: This is incorrect because sildenafil and nitrates do not cause a significant increase in pulse rate, but rather a decrease. This is because the vasodilation caused by both drugs lowers the blood pressure and the cardiac output, which reduces the heart rate.
Choice C reason: This is incorrect because sildenafil and nitrates do not increase the risk of bleeding, unless they are combined with other drugs that affect the blood clotting process, such as anticoagulants or antiplatelets.
Choice D reason: This is correct because sildenafil and nitrates can cause a significant decrease in blood pressure when taken together, as they both cause vasodilation and increase nitric oxide levels. This can lead to hypotension, dizziness, fainting, or even a heart attack or stroke. The patient should avoid taking sildenafil and nitrates within 24 hours of each other.
Correct Answer is D
Explanation
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.
