NCLEX Questions on Gastrointestinal System Questions
Question 1 of 5
What is the purpose of including bismuth subsalicylate in the treatment regimen for PUD?
Correct Answer: B
Rationale: Bismuth subsalicylate coats the ulcer, forming a protective barrier against acid and pepsin.
Question 2 of 5
A patient with PUD is being discharged with a prescription for misoprostol. What important teaching should the nurse provide?
Correct Answer: B
Rationale: Misoprostol can cause uterine contractions and is contraindicated in pregnancy, requiring this key instruction.
Question 3 of 5
A patient with PUD is started on a proton pump inhibitor (PPI). The nurse should monitor for which potential side effect of long-term PPI use?
Correct Answer: B
Rationale: Long-term PPI use reduces calcium absorption, increasing osteoporosis risk.
Question 4 of 5
A patient with a known history of PUD presents with sudden, severe epigastric pain and vomiting. The nurse suspects a perforation. What diagnostic test should be performed immediately?
Correct Answer: D
Rationale: A CT scan quickly confirms perforation by detecting free air or fluid.
Question 5 of 5
Which statement best describes the underlying cause of peptic ulcer disease?
Correct Answer: A
Rationale: Peptic ulcer disease results from an imbalance between aggressive factors (gastric acid, pepsin) and protective factors (mucus, bicarbonate), leading to mucosal erosion. Esophageal inflammation describes GERD, not PUD. Insulin overproduction is unrelated to PUD. Pancreatic duct blockage pertains to pancreatitis, not ulcers.
