Answer to Question 1

ANS: B
PA is a deficiency of vitamin B12 (not folate) because of a lack of IF, which is required for absorption. The vitamin is usually administered by injection through muscle. Because IF deficiency is the actual defect, taking vitamin B12 orally will be of no benefit because it cannot be absorbed. Administering it by injection bypasses the need for absorption.

Answer to Question 2

ANS: A
The easiest test for the patient would be a vitamin B12 assay. All that is required for this test is a venipuncture. The other tests are all much more invasive.
