Question 1 of 5

Question 3 of 5

Which of the following clients is at highest risk for developing gastritis?

Correct Answer: C

Rationale: Chronic NSAID use, as in the 65-year-old male, is a well-established risk factor for gastritis due to its inhibition of prostaglandin synthesis, which protects the stomach lining. Chronic smoking increases risk but less directly than NSAIDs. Occasional alcohol use is a lower risk compared to chronic use. Family history of hypertension is unrelated to gastritis risk.
