A 42-year-old Hispanic woman presents to the primary care office complaining of 24 hours of severe, steady epigastric abdominal pain, radiating to her back, with several episodes of nausea and vomiting. She has experienced similar painful episodes in the past, usually in the evening following heavy meals, but the episodes always resolved spontaneously within an hour or two. This time the pain did not improve, so she sought medical attention. She has no medical history and takes no medications. She is married, has three children, and does not drink alcohol or smoke cigarettes. On examination, she is afebrile, tachycardic with a heart rate of 104 bpm, blood pressure 115/74 mm Hg, and shallow respirations of 22 breaths per minute. She is moving uncomfortably on the stretcher, her skin is warm and diaphoretic, and she has scleral icterus. Her abdomen is soft, mildly distended with marked right upper quadrant and epigastric tenderness to palpation, hypoactive bowel sounds, and no masses or organomegaly appreciated. • What is the probable diagnosis? • What are other possible diagnoses? • At this stage of the case study, what diagnostic studies and basic treatments are most appropriate to order and why?
