What symptom should a patient with a history of preeclampsia be instructed to report immediately?

A patient with a history of preeclampsia should be instructed to report symptoms such as headache and blurry vision immediately because these can be indicative of worsening hypertension or the development of complications such as eclampsia. Preeclampsia is characterized by high blood pressure and potential damage to other organs, and both severe headaches and visual disturbances may signal a critical escalation in the condition, such as increased intracranial pressure or significant cerebral edema.

Timely recognition and management of these symptoms are crucial, as they can prevent serious complications for both the mother and the fetus. While other symptoms like fatigue, muscle weakness, increased thirst, and dry mouth may also require attention, they do not typically signal an immediate and severe threat that warrants urgent reporting in patients with preeclampsia history. Frequent urination and abdominal pain can be caused by a variety of conditions and are not specific indicators of an impending crisis in this context.
