Answer to Question 1

ANS: D
Moderate acne requires a stronger concentration of benzoyl peroxide (10) and possibly topical antibiotics. Isotretinoin is used for severe cystic acne. Systemic antibiotics are given for severe acne.

Answer to Question 2

ANS: A
Patients taking methoxsalen can develop burning and blistering with exposure to sunlight. These signs do not indicate efficacy of the treatment and do not mean the psoriasis is worsening. There is no indication for taking the drug after the UVA exposure.
