Answer to Question 1

C
Feedback:
Diltiazem is administered intravenously to treat acute supraventricular tachycardia. Bethanechol is used to treat neurogenic bladder. Chlorambucil (Leukeran) is an antineoplastic agent used to treat chronic lymphocytic leukemia. Midazolam hydrochloride is administered to reduce anxiety.

Answer to Question 2

B
Feedback:
Although use of INH by itself for treatment of latent TB is appropriate, use with other anti-TB drugs is essential for treatment of active TB. INH would not be used exclusively in the treatment of HIV or MAC.
