Q. |
Pregnant women usually become deficient in - |
A. | Sodium and Calcium |
B. | Iron and Sodium |
C. | Calcium and Iron |
D. | Magnesium and Iron |
Answer» C. Calcium and Iron | |
Explanation: When a woman becomes pregnant her body undergoes many physiological changes. Her hormone levels change not only to support the pregnancy but also to help redirect nutrients to support the nutritional demands of the developing baby. During pregnancy, a woman's blood volume increases 35 percent to 40 percent. Red blood cells contain the protein hemoglobin, which requires the mineral iron. Hemoglobin carries the oxygen to the cells throughout the mother and baby, making iron an important nutrient. Because the plasma volume increases by up to 50 percent but the red blood cells mass increases by only 15 percent to 20 percent, the risk of developing iron-deficiency anemia increases during pregnancy. |
