Which physiological change during pregnancy would a nurse inform the antepartum client is an expected and normal adaptation?
Frequent vomiting persisting into the second trimester
Swelling in one leg with discomfort
Increased blood volume to support fetal and maternal needs
Persistent severe back pain starting in early pregnancy
Increased blood volume during pregnancy is a physiological change that supports the enhanced metabolic demands of the mother and fetus. This adjustment improves oxygen and nutrient delivery while helping accommodate additional maternal tissue growth. In contrast, swelling in only one leg could indicate a deep vein thrombosis (DVT), a serious condition requiring medical attention. Frequent vomiting persisting into the second trimester may signal hyperemesis gravidarum, a complication rather than a normal change. Persistent back pain may suggest musculoskeletal strain but should still be evaluated as it can interfere with daily activities and might signal complications if severe.
