Question

Which is the biggest cause of ulcers of the stomach and duodenum?

Answers

  1. NSAIDs

  2. Stress
    • Rationale:

      This answer is not correct because stress is not exactly a cause of peptic ulcers. The EFFECTS of stress is the cause of peptic ulcers and when clients turn to unhealthy habits due to the stress they are experiencing.

  3. Alcohol
