Answer to Question 1

ANS: C
In early stage 1 iron deficiency, the red cell mass in circulation is unaffected, so anemia is not present and the MCV is normal. However, iron stores are being depleted, so ferritin is decreased.

Answer to Question 2

ANS: B
Ascorbic acid enhances iron absorption. Iron in vegetables is nonheme iron, and it is not readily absorbed. Desferrioxamine chelates iron and is used therapeutically for patients with transfusion-dependent hemochromatosis. Repeated phlebotomy depletes iron, and it is the treatment used for patients with the hereditary form of hemochromatosis.
