Review Question - QID 210078

A 26-year-old G1P0 woman in her 1st trimester is brought to the emergency room by her spouse for persistently erratic behavior. She has been sleeping roughly 1 hour a night, and it sometimes seems like she’s talking to herself. She has maxed out their credit cards on baby clothes. This has been going on for over 1 month. Since first seeing a physician, she has been prescribed multiple 1st and 2nd-generation antipsychotics, but the patient’s spouse reports that her behavior has failed to improve. Her temperature is 98.6°F (37.0°C), blood pressure is 137/98 mmHg, pulse is 90/min, respirations are 14/min, and oxygen saturation is 98% on room air. Upon examination, the patient is speaking rapidly and occasionally gets up to pace the room. She reports she is doing “amazing,” and that she is “so excited for the baby to get here because I’m going to be the best mom.” She denies illicit drug use, audiovisual hallucinations, or suicidal ideation. The attending psychiatrist prescribes a mortality-lowering medication the patient has not yet tried to treat the patient’s psychiatric condition. In terms of this new medication, which of the following is the unborn fetus most likely at increased risk for?
