A 19-year-old woman presents to the emergency department with light-headedness, severe abdominal pain, and intractable nausea and vomiting that began 12 hours earlier. The patient reports previous episodes of abdominal pain and swelling of her hands and feet that have been attributed possibly to food allergies, which have recently become more frequent. How should her case be evaluated and treated?
