During pregnancy, what is the expected change in blood volume?

• A. Decreases significantly
• B. Stays the same
• C. Increases significantly
• D. Increases slightly

Answer: (C)

During pregnancy, the expected change in blood volume is a significant increase. This increase is crucial for supporting the growing fetus, ensuring adequate placental circulation, and preparing the mother's body for labor and delivery. Blood volume can increase by approximately 30% to 50% during pregnancy, which helps meet the metabolic needs of both the mother and the developing baby. The increase in blood volume also serves to enhance cardiac output, as it ensures that there is sufficient blood flow to vital organs and tissues, both for the mother and the fetus. Additionally, this adaptation helps to protect against potential blood loss during childbirth. In summary, the choice indicating a significant increase in blood volume aligns with physiological changes that facilitate a healthy pregnancy and support the demands of both the mother and the fetus.
