B) Bowel obstruction
C) Liver cancer
D) Peptic ulcer disease - D) Peptic ulcer disease

for adding bismuth to the patient's medication regimen?
A) Increases pepsin activity
B) Decreases gastrin secretion
C) Prevents metabolic alkalosis
D) Protects gastric mucosa from stomach acid - D) Protects gastric mucosa from stomach acid

A) Headache
B) Drug-to-drug interaction
C) Diarrhea

Rationale:
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.

following conditions?
A) Hepatic disease
B) Cancer

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.

patient aged 23 years to report postmenopausal bleeding. The medication should be administered
two to four times per day.
