The patient is a 58-year-old female with chronic renal insufficiency, diabetes mellitus, hypertension, and anemia who presented with two weeks of diffuse abdominal pain that acutely worsened one day prior to admission with associated nausea, nonbloody emesis, and chills. She was initially given a seven-day course of ciprofloxacin and oxycodone for pain, but stopped taking them after developing constipation. She currently presents with complaints of diarrhea and was given ampicillin 2 g IV, gentamicin 80 mg IV, Flagyl 500 mg IV and 8 units of insulin. She was put on levofloxacin, vancomycin, and Flagyl as her left foot had been encasted with evidence of underlying infection, and her blood cultures grew MRSA, which is presumed to need eight weeks of vancomycin. She was put on erythromycin with a change to Reglan on 8/6/06 per renal or liver disease and kept on Compazine for nausea. Later, it was determined that the patient was iron deficient and she was put on iron supplementation and darbepoetin initially and changed to erythropoietin later during dialysis. She was maintained on aspirin, a statin, and calcium channel blocker, and started on prophylactic beta-blocker during her hospital course. Her insulin regimen was titrated to good glycemic response, and she was kept on heparin and Nexium.
