Final answer:
Famotidine is the medication that inhibits gastric acid secretion, helpful in treating peptic ulcer disease.
Step-by-step explanation:
A nurse is providing discharge teaching for a client who has a new prescription for medications to treat peptic ulcer disease. Among the options given, the drug that inhibits gastric acid secretion is Famotidine. Famotidine is part of a class of medications called H₂ blockers which decrease the amount of acid made in the stomach and are used to treat ulcers and conditions like GERD and Zollinger-Ellison syndrome. Calcium carbonate and aluminum hydroxide are antacids that neutralize existing stomach acid but do not inhibit its secretion, and sucralfate is a medication that coats the ulcer and protects it from acid but also does not inhibit acid secretion. Famotidine is a medication that belongs to the class of medications called H₂ blockers. It decreases the amount of acid made in the stomach and is commonly used to treat peptic ulcer disease, gastroesophageal reflux disease (GERD), and conditions where the stomach produces too much acid. Other examples of H₂ blockers include ranitidine (Zantac) and cimetidine (Tagamet).
