A nurse is caring for a client who has nausea and a prescription for metoclopramide intermittent IV bolus every 4 hr as needed. The client asks the nurse how metoclopramide Will relieve her nausea. Which of the following explanations should the nurse provide?
“The medication works by decreasing gastric acid secretions”
"The medication relieves nausea by promoting gastric emptying."
"The medication relieves nausea slowing peristalsis.
"The medication works by relaxing gastric muscles”
The Correct Answer is B
Metoclopramide is a prokinetic agent that increases the motility of the upper gastrointestinal tract. Metoclopramide helps accelerate gastric emptying and promotes movement of food through the digestive system. This action can alleviate symptoms of nausea and vomiting by reducing the likelihood of food staying in the stomach for an extended period, which can contribute to feelings of discomfort.
A. Metoclopramide does not increase or decrease gastric acid secretions.
C. Metoclopramide accelerates peristalsis or the movement of food through the gastrointestinal tract.
D. Metoclopramide increases muscle tone and GI motility
