ATI N180 Pharmacology Quiz 2 Questions

Extract:


Question 1 of 5

A nurse is preparing to educate a patient who has newly been prescribed sucralfate (Carafate) for the management of peptic ulcer disease (PUD). What is the mechanism of action for this medication?

Correct Answer: D

Rationale: The correct answer is D: Creates a protective barrier that adheres to an ulcer, which can stick to the ulcer for up to 6 hours. Sucralfate works by forming a protective barrier at the site of the ulcer, which acts as a physical barrier against gastric acid, pepsin, and bile salts, allowing the ulcer to heal. This mechanism helps to promote ulcer healing by providing a protective environment for the ulcer to repair itself.
Other choices are incorrect because:
A: Neutralizing the acidity of gastric acid is not the mechanism of sucralfate.
B: Sucralfate is not an endogenous prostaglandin.
C: Antagonizing H2 receptors is the mechanism of H2 antagonists, not sucralfate.
