This question tests the application of infection control precautions. The key factor in determining the appropriate precaution is the contact transmission mode of MRSA through direct contact with the draining wound. Implementing contact precautions with gown and gloves for room entry is the priority because it prevents the spread of resistant bacteria via hands or clothing. Airborne precautions are for airborne pathogens like TB, droplet precautions address respiratory droplets, and sterile gloves without a gown do not fully protect against contact transmission, making them incorrect. Infection control principles emphasize using barrier precautions to interrupt contact transmission of multidrug-resistant organisms. Guidelines from the CDC recommend dedicating equipment and thorough cleaning to prevent cross-contamination. A transferable strategy is to don PPE before entering rooms of clients with known resistant infections and perform hand hygiene after removal to protect other clients and staff.
