A 30-yeаr-оld pregnаnt wоmаn at 32 weeks gestatiоn presents to triage with a sudden onset of a severe, throbbing headache that has lasted for the past 45 minutes. She has not attempted to take any medication. She reports nausea but denies any vision changes, photophobia, or weakness. Her medical history is unremarkable, and her prenatal visits have been routine, with normal blood pressure. On examination, her blood pressure is 150/95 mm Hg, and there is mild swelling in her ankles. What should the nurse do first?
