Answer to Question 1

ANS: A
The acute phase reactants hepcidin, lactoferrin, and ferritin all contribute to impairing the mobilization of iron for erythropoiesis. Bone marrow iron stores are actually normal to increased in ACI.

Answer to Question 2

ANS: C
The iron studies all point to iron deficiency: low serum iron and ferritin, with an elevated TIBC. Cow's milk is a very poor source of iron, so the infant is not getting adequate iron to support an expanding erythron.
