Q. A 26-year-old primigravida at 24 weeks gestation comes to her obstetrician for a routine antenatal visit. Her pregnancy has been uneventful so far. She reports that she enjoys playing with her cat at home and gardening. Her temperature is 98.6°F (37°C), pulse is 84/min, blood pressure is 120/80 mmHg, and respirations are 13/min. On physical examination, her fundal height measures 22 cm, which is below the expected range for her gestational age. An ultrasound is performed, which shows signs of symmetric intrauterine growth restriction and intracranial calcifications. What is the next best step in her management?
