Answer to Question 1

C
Fidaxomicin is indicated only for treatment of C. difficileassociated diarrhea. The other macrolides are not used for this purpose.

Answer to Question 2

A
Selegiline is safe for patients with glaucoma and emphysema. Benztropine is contraindicated in patients with glaucoma and emphysema. Dopamine precursors, such as carbidopa/levodopa, are contraindicated in patients with narrow-angle glaucoma and cautioned in patients with emphysema.
