Which of the following is NOT typically a symptom of pregnancy-induced hypertension?

Fluid retention is typically associated with pregnancy; however, in the context of pregnancy-induced hypertension (also known as gestational hypertension), it is not a specific symptom linked to the condition itself. Pregnancy-induced hypertension often presents with symptoms like swelling, dizziness, and severe headaches, which are indicative of potential complications such as preeclampsia.

Swelling can be a normal part of pregnancy but, in the context of hypertension, is notable especially if it is sudden or excessive. Dizziness may arise due to fluctuations in blood pressure or other physiological changes during pregnancy. Severe headaches in this scenario can signify increased blood pressure and potential complications or worsening of the condition.

While fluid retention might occur during pregnancy, in cases of pregnancy-induced hypertension, the focus is more on the significant changes in blood pressure and the associated symptoms that can lead to more serious health concerns for the mother and fetus. Thus, fluid retention is not a defining symptom of pregnancy-induced hypertension itself, making it the correct answer in this context.
