A 48-year-old male is returned from endoscopy with a diagnosis of a duodenal ulcer. The nurse is aware that the most likely causative agent for this ulcer is:
1. H. pylori.
2. prolonged NSAID use.
3. intermittent use of glucocorticoids.
4. chronic stress.
Correct Answer: 1
Rationale 1: H. pylori–associated ulcers are most likely to be duodenal.
Rationale 2: NSAID-related ulcers are more likely to produce gastric ulcers.
Rationale 3: Intermittent use of glucocorticoids is not the most common causative agent for this client population.
Rationale 4: Chronic stress is not the most common causative agent for this client population.
Global Rationale: Duodenal ulcers are more likely to be associated with h. pylori infection. NSAID use is morel likely to result in gastric ulcers. Intermittent use of glucocorticoids is not a significant risk factor for duodenal ulcers. Chronic stress is a less likely agent than it infection.
