Answer to Question 1

Ans: A
Feedback:
Cimetidine, when given concurrently with quinidine, may cause an increase in serum quinidine levels. Hydantoins and nifedipine cause a decrease in serum quinidine levels. Rifampin does not interact with quinidine.

Answer to Question 2

Ans: C
Feedback:
The nurse should inform the client that peripheral edema could be an adverse reaction to verapamil therapy. Diarrhea, hyperactivity, and hypertension are not adverse reactions associated with verapamil therapy. Other adverse reactions associated with verapamil are constipation, mental depression, and hypotension.
