Answer to Question 1

ANS: C
Allergy skin testing may be falsely negative in patients taking dimenhydrinate, diphenhydramine, and meclizine at the time of testing. Discontinue diphenhydramine 4 days before testing.

Answer to Question 2

ANS: D
Hydroxyzine is an antihistamine that is also an anticholinergic because it blocks the action of ac-etylcholine in the brain. As such, it causes sedation as the most significant adverse effect.
