During pregnancy, which range of blood pressure is considered abnormal for the second trimester?

During the second trimester of pregnancy, the expected range for blood pressure typically lies around 120/80 mmHg. A blood pressure reading of 140/90 mmHg or higher is considered abnormal and may indicate the presence of hypertension. This is important because detecting abnormal blood pressures is critical for managing potential complications such as preeclampsia, which can have serious consequences for both the mother and the fetus.

High blood pressure in pregnancy can lead to various health issues, so understanding the thresholds for abnormal readings is crucial. The other options present blood pressure readings within the normal range or close enough to it, which do not raise immediate concerns or warrant intervention as hypertension would. Recognizing and responding to elevated blood pressure readings form an essential part of prenatal care to ensure the safety and health of both mother and child.
