A. “The medication works by relaxing gastric muscles." B. "The medication relieves nausea by slowing peristalsis." C. “The medication relieves nausea by promoting gastric emptying." D. “The medication works by decreasing gastric acid secretions."

Correct Answer is C

Explanation

A. “The medication works by relaxing gastric muscles." Metoclopramide stimulates gastric motility rather than relaxing muscles.

B. "The medication relieves nausea by slowing peristalsis." Metoclopramide actually increases peristalsis to help empty the stomach.

C. "The medication relieves nausea by promoting gastric emptying." Metoclopramide is a prokinetic agent that enhances stomach emptying, which helps reduce nausea.

D. "The medication works by decreasing gastric acid secretions." Metoclopramide does not reduce acid secretion; it improves gastric motility.
