(select all that apply.) a take within 30 to 60 minutes of sexual stimulation. b report rebound priapism that occurs for 4 hours or more. c most effective if taken after at least 6 hours of rem sleep. d can cause facial flushing and headache. e frequent use can lead to the development of hypertension.

Explanation:

• Option A: Sildenafil is taken about 30 - 60 minutes before sexual activity (not within 30 - 60 minutes of stimulation), so A is incorrect.
• Option B: Priapism (prolonged erection >4 hours) is a serious adverse effect of sildenafil and needs to be reported, so B is correct.
• Option C: There is no relation between REM sleep and sildenafil effectiveness, so C is incorrect.
• Option D: Facial flushing and headache are common side effects of sildenafil, so D is correct.
• Option E: Sildenafil is used to treat pulmonary hypertension and generally does not cause hypertension with frequent use; in fact, it can lower blood pressure, so E is incorrect.

Answer:

B. Report rebound priapism that occurs for 4 hours or more, D. Can cause facial flushing and headache
