A nurse is admitting a patient who is at 38 weeks gestation and has severe pre-eclampsia. When assessing the patient, the nurse should expect which finding?

A. Pre-eclampsia is usually associated with oliguria (reduced urine output) due to renal vasoconstriction and decreased glomerular filtration. Polyuria is not expected and may indicate another condition, such as diabetes mellitus. B. While mild increases in heart rate can occur, tachycardia is not a hallmark sign of pre-eclampsia. Blood pressure elevation, rather than heart rate changes, is the primary cardiovascular finding. C. Severe pre-eclampsia is characterized by hypertension with systemic involvement, and persistent, severe headaches are common due to cerebral edema and vasospasm. Headaches are a classic symptom and often a warning sign for potential complications such as eclampsia. D. Visual disturbances can occur in pre-eclampsia (e.g., blurred vision, scotomata, or spots), but diplopia (double vision) is less common. Headache is a more consistent and expected finding in severe pre-eclampsia.
