Final answer:
The therapy for the patient should consist of IV fluid hydration, analgesia, and intensive care management.
Step-by-step explanation:
The therapy for this patient should consist of IV fluid hydration, analgesia, and intensive care management. Based on the patient's presentation with acute abdominal pain and anorexia, along with the history of alcoholism, a likely diagnosis is acute pancreatitis. This is supported by the physical exam findings of tenderness to palpation over the epigastrium. The high heart rate and low blood pressure indicate signs of shock, which require intensive care management. Providing intravenous fluids for hydration and analgesia for pain relief would be appropriate initial therapy in this scenario.
