Which finding in a prenatal clinic assessment indicates a need for further evaluation?

In a prenatal clinic assessment, an increase in diastolic blood pressure of 15 mm Hg at 20 weeks gestation indicates a significant change that warrants further evaluation. Blood pressure monitoring is crucial during pregnancy because elevated levels can signal potential complications such as gestational hypertension or preeclampsia.

A normal diastolic blood pressure typically varies but a notable increase, especially a jump of 15 mm Hg, could suggest that the body is struggling to maintain vascular stability or could be experiencing increased vascular resistance. These factors can lead to serious risks for both the mother and fetus. Therefore, further evaluation is essential to monitor the condition, assess the mother's overall health, and potentially implement interventions to prevent complications.

In contrast, weight gain of 2 lb at 9 weeks gestation is not unusual as early pregnancy often entails minimal weight changes. Headaches at 15 weeks that respond to acetaminophen can be common and don’t necessarily indicate a need for concern. Similarly, bleeding gums after dental care can be attributed to increased blood flow and hormonal changes during pregnancy, frequently seen without significant risk. These findings are more typical of normal pregnancy variations rather than indicators of potential complications.
