What is the hemoglobin level indicative of anemia in the first or third trimester of pregnancy?

  1. Less than 12

  2. Less than 11

  3. Less than 10.5

  4. Less than 9

The correct answer is: Less than 11

During pregnancy, anemia is a common concern due to the increased demands for iron and other nutrients to support the growing fetus. The hemoglobin level that indicates anemia can vary slightly based on the trimester. In the context of the first and third trimesters, a hemoglobin level of less than 11 grams per deciliter is recognized as indicative of anemia. This threshold is set lower than the normal adult female level due to physiological changes during pregnancy, such as increased plasma volume leading to hemodilution. Recognizing anemia at this level is crucial for timely intervention and management, which may include dietary modifications or supplementation, to ensure both maternal and fetal health. Other options suggesting higher thresholds are not used in this clinical context, as they do not capture the condition of anemia properly during these specific trimesters.
