You are called to the A&E (E.R.) department of your tertiary center to assist in the care of your patient, a 22-year-old primigravida at 14+4 weeks’ gestation who presents, accompanied by her partner, with a six-hour history of nausea, vomiting, and headache since her last consumed six-daily standard drinks of beer yesterday. At last week’s baseline prenatal visit, you learned that medical history is only significant for an alcohol use disorder, for which she was motivated to enroll in a treatment program. Your medical notes indicate a normal body habitus and unremarkable physical exam. Prenatal investigations and first-trimester aneuploidy screening tests were normal. You had prescribed vitamins containing folic acid; the patient was not experiencing nausea or vomiting of pregnancy.
