Answer to Question 1

Ans:
D

Feedback:

After release from the marrow, the neutrophils spend only approximately 4 to 8 hours in the circulation before moving into the tissues. They survive in the tissues for approximately 4 to 5 days. They die in the tissues by discharging their phagocytic function.

Answer to Question 2

Ans:
D

Feedback:

Formula and cereals for infants should be iron fortified to preclude iron deficiency anemia. Breast-feeding does not necessarily mitigate the need for iron supplementation, and cow's milk does not deplete existing iron stores but fails to provide sufficient levels of absorbable iron. Infants and children have significantly higher iron needs than do adults.
