Patient with immunosuppression (chemotherapy) and repeated insertion of a catheter (notorious for causing nosocomial Staph and Strep infections) who presents with fever and discharge from catheter site found to have an infection with gram-positive cocci in clusters (= Staph aureus or Staph epidermidis) who should be initially treated with Vancomycin to cover MRSA until sensitivities return
Key idea: Rates of MRSA are higher in patients who develop nosocomial Staph infections compared to community Staph infections
The only cephalosporin that covers MRSA is ceftaroline (5th generation cephalosporin)
