What is the primary concern for nursing management in a pregnant woman with a history of hypertension?

The primary concern for nursing management in a pregnant woman with a history of hypertension is to monitor for changes in blood pressure and fetal well-being. This focus is crucial because hypertension during pregnancy can lead to serious complications such as preeclampsia, placental abruption, and restricted growth of the fetus. Consistent monitoring allows healthcare providers to identify any concerning trends in blood pressure that could threaten both the mother’s and the baby's health.

Additionally, monitoring fetal well-being through assessments like ultrasound, fetal heart rate monitoring, and evaluation of fetal movement is vital to ensure the baby is not adversely affected by maternal hypertension. This comprehensive approach allows for timely interventions, which can significantly improve outcomes for both the mother and the fetus.

While monitoring for signs of swelling might be relevant, it is not as central as tracking blood pressure and fetal well-being. Encouraging rest and relaxation techniques can be supportive for overall health but does not directly address the immediate risks posed by the existing hypertension. Lastly, maintaining a high-calcium diet, while important for pregnant women, is not a primary nursing management priority related to hypertension.
