Which vital sign changes are typical in pregnant women?

In pregnant women, it is common for the heart rate to increase by 10-15 beats per minute. This increase occurs due to various physiological changes that take place during pregnancy. As the body accommodates the growing fetus, there is a need for increased blood flow and oxygen delivery to both the mother and the baby. An elevated heart rate helps to support this increased demand for circulation.

Other changes accompany this increase in heart rate, such as expansions in blood volume and metabolic demands. It’s important to note that while blood volume does increase during pregnancy to support fetal needs, blood pressure often remains stable or can decrease slightly due to vasodilation. Therefore, the options indicating decreased blood volume or increased blood pressure are not typical responses during pregnancy. Understanding these physiological changes is crucial for healthcare providers in assessing and managing the health of pregnant patients.
