Write answer in between .Q:Three days after admission to the hospital following a motor vehicle accident, a 45-year-old woman develops a fever. A central venous catheter was placed on the day of admission for treatment of severe hypotension. Her temperature is 39.2C 102.5F. Examination shows erythema surrounding the catheter insertion site at the right internal jugular vein. Blood cultures show gram-positive, catalase-positive cocci that have a low minimum inhibitory concentration when exposed to novobiocin. Which of the following is the most appropriate pharmacotherapy?? A: Metronidazole, B: Vancomycin, C: Clarithromycin, D: Penicillin G, E: Polymyxin B,  <response>: This is a medical question involving a patient who developed a fever 3 days after being admitted to the hospital for a motor vehicle accident. The patient has a central venous catheter that was placed on admission to treat severe hypotension. The fever and erythema around the catheter insertion site suggest the patient has developed a catheter-related bloodstream infection. The blood cultures show gram-positive, catalase-positive cocci that are susceptible to novobiocin, which indicates the bacteria are likely Staphylococcus aureus. This is a common cause of catheter-related infections.The question is asking for the most appropriate antibiotic to treat this infection. Methronidazole, clarithromycin, and polymyxin B would not cover S. aureus. Penicillin G may be an option but some S. aureus are penicillin-resistant. Vancomycin would provide appropriate coverage for methicillin-resistant S. aureus and is the best answer.B: Vancomycin
