Answer to Question 1

ANS: C
Haptocorrin is a salivary protein that binds vitamin B12 found in food. In the small intestine the vitamin is released from haptocorrin by the action of trypsin. IF is then required for its absorption into circulation. Transcobalamin is the most important of the plasma carrier proteins for vitamin B12.

Answer to Question 2

ANS: D
The blood picture findings point to a megaloblastic anemia. The first test to order would be the vitamin B12 and folate assays to determine which of these two vitamins is deficient.
