During the second trimester, maternal blood pressure typically does what?

Explanation:
During the second trimester, pregnancy causes hormonal vasodilation that lowers systemic vascular resistance. With less resistance, maternal blood pressure tends to fall modestly. The typical change is a decrease of about 10–15 mmHg, which is why this option is the best answer. This drop is a normal mid-pregnancy adaptation; blood pressure often returns toward baseline or may rise slightly in the third trimester as the pregnancy progresses. A much larger drop or a rise would be more concerning and warrant further evaluation.
