A nurse is reviewing a client's laboratory results and finds a low mean corpuscular volume (MCV). Which type of anemia does this finding suggest?

A) This choice is incorrect because pernicious anemia is not related to iron deficiency, so increasing iron-rich foods will not address the underlying cause.

B) This choice is incorrect because vitamin C actually enhances the absorption of vitamin B12, which is essential in pernicious anemia.

C) This choice is correct. Pernicious anemia is caused by the lack of intrinsic factor, a protein necessary for vitamin B12 absorption. Clients with pernicious anemia will require lifelong vitamin B12 supplementation, often through intramuscular injections.

D) This choice is incorrect. Leafy green vegetables are good sources of folate, which is not directly related to pernicious anemia.

A) This choice is incorrect because monitoring the client's temperature is important, but it is not the priority during the PRBC transfusion process.

B) This choice is incorrect because administering pain medication may be necessary if the client is experiencing discomfort during or after the transfusion, but it is not the priority action.

C) This choice is incorrect because obtaining informed consent is an essential step before any medical intervention, including transfusions, but it is not the priority during the transfusion process.

D) This choice is correct. Checking the client's blood type is a priority before administering a PRBC transfusion to ensure compatibility and prevent adverse reactions. Transfusion reactions can be life-threatening, so verifying the blood type is crucial for client safety.
