A client at 28-weeks gestation whose hemoglobin level is 10.7 g/dL (107 g/L) and hematocrit is 32% (0.32 volume fraction) tells the nurse that she eats plenty of green vegetables. When the client asks the nurse how the low value might affect her pregnancy, which information should the nurse provide?

Choice A rationale While increasing protein intake is beneficial for overall health and pregnancy, it is not the primary factor that affects hemoglobin and hematocrit levels. These levels are more directly influenced by iron intake and the physiological changes during pregnancy. Protein intake is important for fetal growth and development, but it does not significantly alter the concentration of hemoglobin or hematocrit in the blood. Choice B rationale During pregnancy, plasma volume increases by approximately 50%, leading to hemodilution. This means that even though the total number of red blood cells increases, the concentration of hemoglobin and hematocrit appears lower due to the larger volume of plasma. This physiological change helps meet the increased oxygen demands of both the mother and the growing fetus and is a normal part of pregnancy. Choice C rationale Taking an iron supplement can help improve hemoglobin and hematocrit levels, especially if a pregnant woman has iron-deficiency anemia. Iron is essential for the production of hemoglobin, which carries oxygen in the blood. However, not all pregnant women with lower hemoglobin and hematocrit levels need to take iron supplements, as these values can be within the expected range for pregnancy. The decision to supplement should be based on individual assessment by a healthcare provider. Choice D rationale Not all women at 28 weeks gestation have anemia. While it is common for hemoglobin and hematocrit levels to be lower during pregnancy due to increased plasma volume, it does not mean that all pregnant women are anemic. Anemia is diagnosed based on specific thresholds for hemoglobin and hematocrit levels, and the values mentioned (hemoglobin 10.7 g/dL and hematocrit 32%) are borderline and may not necessarily indicate anemia.
