Answer to Question 1

B
Feedback:
Digoxin immune Fab is an antigen-binding fragment derived from specific antidigoxin antibodies. The drug is used for the treatment of life-threatening digoxin intoxication when serum levels are greater than 10 ng/mL. Inamrinone is a phosphodiesterase inhibitor that acts as a cardiotonic agent. Verapamil hydrochloride is a calcium channel blocker. Quinidine is an antiarrhythmic agent that when taken with digoxin increases both the therapeutic and toxic effects of digoxin.

Answer to Question 2

B
Feedback:
Ropinirole is a newer drug that directly stimulates dopamine receptors. It is also used to treat restless legs syndrome. The other options are incorrect because ropinirole only works as a dopamine receptor stimulant.
