A 33-year-old woman presented to the emergency department as a restrained driver in a motor vehicle collision with air bag deployment. The patient had diffuse lower abdominal pain with nausea and one episode of emesis. Her vital signs were notable for a blood pressure of 108/69 mm Hg and a heart rate of 124 beats/min. Physical examination findings revealed tachycardia and a distended, diffusely tender abdomen without evidence of a seatbelt sign or peritonitis. Her laboratory findings were unremarkable except for a hemoglobin level of 10.5 g/dL (to convert to grams per liter, multiply by 10) and a white blood cell count of 21 300/μL (to convert to ×109/L, multiply by 0.001). Her medical history was significant only for asthma.
