A 36-year-old G2P1 woman at “about 4 months” of gestation presents to her obstetrician for her first prenatal visit. She has been
feeling well, but has not been to see a physician yet because of a death in the family. Her past medical history is significant for chronic hypertension, which is currently well controlled on a calcium channel blocker, and for Raynaud’s syndrome, also well controlled. Her blood pressure is 125/85 mm Hg, heart rate is 95/min, and respiratory rate is 18/min. Which is the most appropriate next step in managing this patient’s hypertension?
