Answer to Question 1

A
Feedback:
No absolute contraindications exist, but cimetidine should be used cautiously in patients with impaired hepatic and renal function. The patient with cancer, hypertension, and diabetes mellitus can take cimetidine safely.

Answer to Question 2

B
Feedback:
Unlike cimetidine, ranitidine (Zantac), famotidine (Pepcid, Pepcid RPD), and nizatidine (Axid) do not affect the cytochrome P450 drug-metabolizing system in the liver and therefore do not interfere with the metabolism of other drugs. Use of these other drugs may be preferable in patients who are critically ill because they often require numerous other drugs with which cimetidine may interact.
