Answer to Question 1

D
Feedback:
Metronidazole (Flagyl) is indicated for use in the treatment of Clostridium difficile. Linezolid (Zyvox) is not used to treat C. difficile. Cladribine (Leustatin) is an antineoplastic agent that is not used for C. difficile. Clarithromycin (Biaxin) is not used to treat C. difficile.

Answer to Question 2

B
Feedback:
Hydrochlorothiazide inhibits the reabsorption of sodium and chloride in the distal renal tubule, increasing the excretion of sodium and water by the kidneys. Thiazide diuretics do not relax smooth muscle, increase contractility, or stimulate the SA node.
