Physiologic anemia often occurs during pregnancy because of:
a. inadequate intake of iron.
b. the fetus establishing iron stores.
c. dilution of hemoglobin concentration.
d. decreased production of erythrocytes.
ANS: C
When blood volume expansion is more pronounced and occurs earlier than the increase in red blood cells, the woman will have physiologic anemia, which is the result of dilution of hemoglobin concentration rather than inadequate hemoglobin. Inadequate intake of iron may lead to true anemia. If the woman does not take an adequate amount of iron, true anemia may occur when the fetus pulls stored iron from the maternal system. There is increased production of erythrocytes during pregnancy.
