Answer to Question 1

ANS: D
Tretinoin increases susceptibility to sunburn, so patients should be warned to apply a sunscreen and wear protective clothing. Before applying Retin-A, the skin should be washed, toweled dry, and allowed to dry fully for 15 to 30 minutes. Retin-A is applied once daily. Abrasive soaps intensify localized reactions to Retin-A and should not be used.

Answer to Question 2

ANS: D
Tretinoin is used to treat fine wrinkles, not coarse wrinkles, and does not repair sun-damaged skin. Treatment with Renova must continue to maintain the response to the drug. Results are not visible for up to 6 months after beginning therapy. Systemic toxicity is not common.
