Chapter 15 The Gastrointestinal System Review Questions Questions
Question 1 of 5
The nurse should advise a patient with PUD to avoid which of the following medications due to the risk of exacerbating the condition?
Correct Answer: D
Rationale: Both NSAIDs and aspirin inhibit prostaglandins, reducing mucosal protection and worsening PUD.
Question 2 of 5
A patient with a history of PUD is admitted for observation after a sudden onset of severe abdominal pain. What diagnostic test would the nurse anticipate being ordered first?
Correct Answer: B
Rationale: A CT scan is often first to quickly identify complications like perforation or bleeding in acute PUD presentations.
Question 3 of 5
A patient with PUD is prescribed a combination therapy of amoxicillin, clarithromycin, and a PPI. The nurse understands that this regimen is intended to:
Correct Answer: C
Rationale: This triple therapy eradicates H. pylori and reduces acid to heal ulcers.
Question 4 of 5
A patient with PUD presents with a sudden onset of severe abdominal pain, vomiting, and signs of peritonitis. What is the nurse's priority action?
Correct Answer: B
Rationale: Signs of peritonitis suggest perforation, requiring immediate physician notification.
Question 5 of 5
Which diagnostic test is most commonly used to confirm the diagnosis of gastritis?
Correct Answer: B
Rationale: Endoscopy with biopsy is the gold standard for diagnosing gastritis as it allows direct visualization of the stomach lining and histological confirmation of inflammation or H. pylori infection. Barium swallow is less specific and used more for structural abnormalities. Abdominal ultrasound assesses organs like the liver or gallbladder, not gastritis. Stool culture is irrelevant unless checking for H. pylori antigen, but it's not the primary method.
