Chapter 30: The gastrointestinal tract MULTIPLE CHOICE

1)The symptomatic treatment of diarrhea may include administration of

1. loperamide
2. lactulose
3. omeprazole
4. bisacodyl

5. cimetidine

2.    Omeprazole reduces gastric acid secretion by

1. reversibly inhibiting the H⁺/Na⁺ ATPase
2. irreversibly inhibiting the H⁺/Na⁺ ATPase
3. reversibly inhibiting the H⁺/K⁺ ATPase
4. irreversibly inhibiting the H⁺/K⁺ ATPase
5. irreversibly inhibiting the Na⁺/K⁺ ATPase

3.    According to the two-cell hypothesis of gastric acid secretion, the parietal cell has receptors for

1. only histamine and acetylcholine
2. only histamine and gastrin
3. only gastrin and acetylcholine
4. only gastrin
5. histamine, gastrin, and acetylcholine

4.    The use of misoprostol in treating gastric damage caused by nonsteroidal anti-inflammatory drugs is partly due to its ability to

1. increase secretion of mucus and bicarbonate
2. decrease secretion of mucus and bicarbonate
3. increase gastrointestinal motility
4. decrease mucosal blood flow
5. inhibit release of histamine

5.    Nausea and vomiting caused by vestibular stimulation is most effectively prevented by

1. ondansetron
2. metoclopramide
3. nabilone
4. promethazine
5. prochlorperazine

6.    Sucralfate is best described as a

1. proton pump inhibitor
2. histamine H1 receptor antagonist
3. substituted benzimidazole
4. prostaglandin E2 analogue
5. complex of aluminum hydroxide and sulfated sucrose

7.    Which drug increases electrolyte and water secretion by the intestinal mucosa?

1. sucralfate
