Answer to Question 1

ANS: D
In stage 3 iron deficiency the red cells are microcytic and hypochromic. Therefore the MCV, MCH, and MCHC are all low. (The MCH is actually lower than would be expected for the red cell size if it had been normochromic.) The reticulocyte count () is low, sometimes thrombocytosis is seen, and the red cells are not macrocytic.

Answer to Question 2

ANS: D
Of the tests listed, only ferritin distinguishes between iron deficiency anemia and ACI; in iron deficiency anemia, it is low, whereas in ACI it is normal to elevated. Serum iron and hemoglobin (if the patient is anemic) are decreased in both; FEP is increased in both.
