Answer to Question 1

A
Feedback:
There is increased risk of excessive hypotension if any of these drugs is combined with volatile liquid general anesthetics such as enflurane, halothane, or isoflurane. The effectiveness of diabetic agents is increased, leading to hypoglycemia when such agents are used with these drugs. Carvedilol has been associated with potentially dangerous conduction system disturbances when combined with verapamil or diltiazem. Vomiting is not associated with this combination of drugs.

Answer to Question 2

D
Feedback:
Cinchonism (nausea, vomiting, tinnitus, and vertigo) may occur with high levels of primaquine. Symptoms of cinchonism do not include diarrhea, abdominal cramping, or tan, frothy stool.
