Past medical history is significant for hepatitis C, complicated by multiple recent visits with associated ascites. His temperature is 38.3C 100.9F, heart rate is 115min, blood pressure is 8848 mm Hg, and respiratory rate is 16min. On physical examination, the patient is alert and in moderate discomfort. Cardiopulmonary examination is unremarkable. Abdominal examination reveals distant bowel sounds on auscultation. There is also mild diffuse abdominal tenderness to palpation with guarding present. The remainder of the physical examination is unremarkable. A paracentesis is performed. Laboratory results are significant for the following:Leukocyte count 11,630μL with 94 neutrophilsPlatelets 24,000μLHematocrit 29Ascitic fluid analysis:Cell count 658 PMNsμL Total protein 1.2 gdL Glucose 24 mgdLGram stain Gram-negative rodsCulture Culture yields growth of E. coliWhich of the following is the next, best step in the management of this patient?? A: Surgical consultation, B: Intravenous fluid resuscitation, C: Intravenous cefotaxime, D: Serum lipase level, E: Abdominal radiography and contrast CT of the abdomen,  <response>: This is a patient with acute abdominal pain and signs of sepsis fever, tachycardia, hypotension. The history of hepatitis C with ascites raises concern for spontaneous bacterial peritonitis. The paracentesis results confirm this diagnosis, with a high neutrophil count, low glucose, and growth of E. coli from the fluid. The next best step is to start antibiotic therapy to treat the infection. Choice C, intravenous cefotaxime, provides appropriate broad-spectrum coverage for gram-negative rods like E. coli. Choices A, B, D, and E may be indicated later in the management but are not the immediate next step.C: Intravenous cefotaxime
