Review Gastrointestinal System Nursing Exam Questions related questions and content

A client has been diagnosed with gastroesophageal reflux disease. The nurse interprets that the client has dysfunction of which of the following parts of the digestive system?

  • A. Chief cells of the stomach
  • B. Parietal cells of the stomach
  • C. Lower esophageal sphincter
  • D. Upper esophageal sphincter
Correct Answer: C

Rationale: The correct answer is C: Lower esophageal sphincter. Gastroesophageal reflux disease (GERD) involves the dysfunction of the lower esophageal sphincter (LES), which fails to close properly, allowing stomach acid to reflux into the esophagus. This leads to symptoms such as heartburn and regurgitation. Choices A and B (Chief cells and Parietal cells of the stomach) are not directly related to GERD, as they are involved in gastric acid secretion. Choice D (Upper esophageal sphincter) is responsible for preventing air from entering the esophagus during breathing and is not typically implicated in GERD.
