1. A male patient is being treated for benign prostatic hyperplasia (BPH) by another provider but cannot remember which drug he is taking. He comes to the clinic seeking treatment for erectile dysfunction and receives a prescription for sildenafil [Viagra]. What will the nurse teach this patient?

ANS:  D

Sildenafil should not be taken with alpha₁-adrenergic antagonists, such as silodosin, because of the risk of severe decreases in blood pressure. Finasteride is not an alpha₁-adrenergic antagonist and may be taken with sildenafil. Not all medications for BPH are safe to take with sildenafil. Invasive treatments for BPH are used when symptoms are severe.

2. A nurse is teaching a patient about the use of sildenafil [Viagra] for erectile dysfunction. Which statement by the patient indicates understanding of the teaching?

ANS:  A

Priapism can occur and can cause tissue damage to the penis, so an erection lasting longer than 4 hours should be reported. Patients who use nitroglycerin should not use sildenafil within 24 hours of taking this drug. Patients should be advised to take sildenafil 30 minutes to 4 hours before anticipated sexual activity. Sildenafil does not cause an erection without sexual stimuli.

3. A 68-year-old male patient receives a prescription for 25-mg tablets of sildenafil [Viagra] for erectile dysfunction. When he asks the nurse how to take the medication, the nurse will tell him to:

ANS:  B

Patients older than 65 years should start with a low dose of 25 mg and may take the drug 1 hour before anticipated sexual activity. Sildenafil is taken when needed and not on a routine basis. Dosing at 25 to 100 mg per dose 30 minutes to 4 hours before sexual activity is the standard recommendation for men younger than 65 years. Two tablets is a high dose; consumption of a high-fat meal would interfere with absorption of sildenafil.

4. A nurse is obtaining a history from a patient who will receive tadalafil [Cialis] for erectile dysfunction. The patient reports that he expects to have sexual activity three or four times a week. What should the nurse tell the patient?

ANS:  D

Tadalafil is approved for daily dosing and can be given daily for men who anticipate sexual activity twice a week or more. Tadalafil has longer effects—up to 36 hours—than sildenafil, and adverse effects take longer to resolve. There is no increased risk of priapism associated with an increase in sexual activity. Because tadalafil has longer effects, dosing and sexual activity do not have to be closely timed.
