Which of the following is used to treat CA-MRSA SSTI?

  1. Vancomycin

  2. Doxycycline

  3. Pen G

  4. Nafcillin

The correct answer is: Doxycycline

Doxycycline is used to treat Community-Acquired Methicillin-Resistant Staphylococcus aureus (CA-MRSA) skin and soft tissue infections (SSTIs) due to its efficacy against MRSA. Doxycycline is a tetracycline antibiotic that works by inhibiting bacterial protein synthesis. Vancomycin is also effective against MRSA infections but is typically reserved for more severe cases due to its potential for nephrotoxicity. Penicillin G and Nafcillin are not effective against MRSA because MRSA is resistant to beta-lactam antibiotics like penicillins and cephalosporins.
