Answer to Question 1

ANS: C
If the ring is expelled for longer than 3 hours, the patient should be instructed to rinse it in cool or lukewarm water, reinsert, and use a nonhormonal backup contraceptive for the next 7 consecutive days of continuous ring use. It is not necessary to insert a new ring after a day.

Answer to Question 2

ANS: A
Sildenafil (Viagra), a phosphodiesterase inhibitor, increases cyclic guanosine monophosphate concentrations in the corpus cavernosum, which results in smooth muscle relaxation and greater blood flow into the corpus cavernosum, producing an erection. Antiandrogen agents, sympathomimetic agents, and adrenergic blocking agents are not effective in treating ED.
