Question 1 of 5
In PUD management, what is the role of sucralfate?
Correct Answer: B
Rationale: The correct answer is B. Sucralfate forms a protective barrier over ulcers by binding to the ulcer site and creating a physical barrier against acid and pepsin. This protects the ulcer from further damage and allows it to heal. The other choices are incorrect because: A: Sucralfate does not neutralize stomach acid, it works by forming a barrier. C: Sucralfate does not eradicate H. pylori, which is typically treated with antibiotics. D: Sucralfate does not inhibit acid production, it works by creating a protective barrier.
Question 2 of 5
Which of the following is an expected outcome of effective PUD management?
Correct Answer: B
Rationale: Step 1: Effective PUD management involves eradicating H. pylori bacteria. Step 2: Absence of H. pylori on follow-up testing indicates successful treatment. Step 3: Therefore, the expected outcome of effective PUD management is the absence of H. pylori on follow-up testing, making choice B the correct answer. Summary: Choices A, C, and D are incorrect as they do not directly relate to the key aspect of PUD management, which is eradicating H. pylori.
Question 3 of 5
Which of the following is a long-term complication of chronic PUD?
Correct Answer: A
Rationale: The correct answer is A: Gastric outlet obstruction. Chronic PUD can lead to scarring and inflammation in the stomach lining, causing narrowing or blockage of the pyloric valve, leading to gastric outlet obstruction. This complication can manifest as persistent nausea, vomiting, and weight loss. The other choices, B, C, and D, are not typically associated with chronic PUD. Gallbladder disease is more commonly linked to gallstones, chronic kidney disease to conditions affecting the kidneys, and pulmonary embolism to blood clots in the lungs.
Question 4 of 5
The nurse is caring for a patient with a newly diagnosed duodenal ulcer. Which statement made by the patient indicates the need for further teaching?
Correct Answer: B
Rationale: The correct answer is B because taking antacids immediately after meals is not recommended for duodenal ulcers. Antacids should be taken 1-3 hours after meals or at bedtime for optimal effectiveness. Choice A is correct as caffeine can stimulate acid production. Choices C and D are also correct as smoking and stress can aggravate duodenal ulcers.
Question 5 of 5
A patient with PUD asks the nurse why it's important to avoid NSAIDs. The nurse's best response is:
Correct Answer: B
Rationale: The correct answer is B because NSAIDs inhibit prostaglandin synthesis, reducing blood flow to the stomach lining, which can lead to ulcer formation. This is important for a patient with PUD as it can exacerbate their condition. Choice A is incorrect as NSAIDs do not cause fluid retention in PUD. Choice C is incorrect as NSAIDs actually decrease mucus production, making the stomach lining more vulnerable. Choice D is incorrect as NSAIDs are more likely to cause gastrointestinal issues like ulcers rather than constipation.
