Question 1 of 5

A client with pernicious anemia asks why she must take vitamin B12 injections for the rest of her life. Which is the nurse's best response?

Correct Answer: B

Rationale: Pernicious anemia results from a lack of intrinsic factor, a gastric protein necessary for vitamin B12 absorption. This necessitates lifelong B12 injections, as oral supplements are ineffective. The other responses are incorrect, as stomach acid, kidney dysfunction, or increased B12 demand are not the primary causes.
