A 46-year-old woman with alcoholism is evaluated because of a 4-day history of nausea and vomiting after a recent binge. She has diffuse epigastric pain. She has been hospitalized intermittently for years for medical complications related to alcohol abuse, including cirrhosis with ascites and bleeding esophageal varices. On physical examination, her temperature is 37.3 °C (99.1 °F), pulse rate is 68/min, and blood pressure is 135/70 mm Hg. She has jaundice and is icteric. Her lungs are clear to auscultation. The remainder of her physical examination is unremarkable.
