What physiological change might a nurse observe in a pregnant woman with preeclampsia?

In a pregnant woman with preeclampsia, the physiological change that can be observed is edema and swelling. Preeclampsia is characterized by high blood pressure and often leads to the accumulation of fluid, particularly in the lower extremities, which can manifest as swelling in the ankles, feet, and sometimes the hands and face. This condition occurs due to increased vascular permeability and altered renal function, resulting in fluid retention.

Edema is one of the hallmark signs of preeclampsia, often accompanied by proteinuria. Nurses must be vigilant in monitoring for these signs, as they can indicate the progression of the disease and potential complications for both the mother and fetus. Recognizing and managing these symptoms is critical in providing appropriate care and ensuring the health of the pregnant woman and her baby.
