What factor may necessitate the use of antihypertensive medication in a postpartum patient with a history of severe preeclampsia?

Elevated blood pressure readings in a postpartum patient with a history of severe preeclampsia are critical in determining the necessity for antihypertensive medication. Severe preeclampsia significantly raises risks for postpartum complications, including the possibility of developing hypertension or eclampsia. Monitoring blood pressure after delivery is essential, as hypertension can persist or occur after childbirth, requiring intervention to prevent further complications. In cases where blood pressure remains elevated, the initiation of antihypertensive therapy is warranted to safely manage the patient's health and reduce the risk of serious outcomes such as stroke or organ dysfunction.

While other factors such as the presence of urinary protein, low reflex responses, or lack of social support may indicate a need for further evaluation or support, they do not directly necessitate antihypertensive treatment in the context of managing blood pressure.
