Question

Which of the following individuals would be LEAST likely to be at risk for B12 deficiency?

A. A vegan
B. A woman with polycystic ovarian syndrome taking metformin therapy
C. An elderly individual on a proton pump inhibitor
D. A man on aspirin therapy

Answer 1

A man on aspirin therapy would be LEAST likely to be at risk for B12 deficiency, as aspirin therapy does not typically cause B12 deficiency unlike the other options listed.

Step-by-step explanation:

The individual who would be LEAST likely to be at risk for B12 deficiency is D. A man on aspirin therapy. This is because aspirin therapy is not typically associated with causing vitamin B12 deficiency. On the other hand, vegans (Option A) are at a higher risk of B12 deficiency due to the absence of animal products in their diet. Women with polycystic ovarian syndrome taking metformin (Option B) can have a higher risk because metformin may interfere with B12 absorption. Elderly individuals on proton pump inhibitors (Option C) may also have an increased risk since these drugs can reduce stomach acid, hindering B12 absorption.
