Q. A 22-year-old primigravida woman at 36 weeks gestation presents to the OB-GYN clinic with a two-week history of swelling in her face, hands, and feet. She mentions that the swelling is persistent and appears to be worsening. She denies any past medical history or significant family history of note. During the examination, her blood pressure is found to be 155/90 mm Hg in her left arm and 160/92 mm Hg in her right arm, measured on two separate occasions. On abdominal examination, her fundal height measures 36 cm, which is appropriate for gestational age. She exhibits no tenderness over the gallbladder, indicated by a negative Murphy sign. The patient has bilateral lower extremity +3 pitting edema, and deep tendon reflexes in the lower extremities are brisk, quantified at +3. Urinalysis is positive for proteinuria, with a reading of >1+ from a morning sample taken at home and confirmed with a similar result at the clinic. In the context of the clinical findings, which of the following is the most likely diagnosis?
