156) Answer

B. 30 mg per day

Rationale

•During pregnancy, approximately 30 mg of iron is needed per day.

•Non-pregnant women require about 18 mg of iron per day.

•Iron is important in the formation of hemoglobin to carry oxygen throughout the body. Iron will be transferred to the fetus even if maternal iron intake is inadequate, but this causes depletion of the mother’s iron stores.
