A 32-year-old primigravida at 28 weeks of gestation visits the Obstetrician’s clinic for her routine antenatal follow-up. Her blood pressure reading is recorded by the nurse as 145/95 mmHg. She is currently not taking any antihypertensive medications. Her urine dipstick is negative for proteinuria, and a foetal ultrasound reveals no signs of foetal growth restriction or distress. Her blood pressure is repeated roughly 4 hours later and it is found to be 140/90 mmHg.
