What type of precautions should be used for applying a negative pressure system?

• A. Standard precautions
• B. Contact precautions
• C. Airborne precautions
• D. Droplet precautions

Answer: (A)

Airborne precautions are used with a negative pressure system because the goal is to prevent aerosols from escaping the room and potentially spreading infection. A negative-pressure room helps contain airborne pathogens, so staff must don protective respiratory protection (a fit-tested N95 respirator or higher) and follow procedures that minimize aerosol dissemination. In addition, a private room with maintained negative pressure and a closed door is needed, and patient transport should be limited with the patient wearing a mask if movement is necessary. Standard precautions are the baseline for all patients, but they do not specifically address airborne transmission; airborne precautions are the appropriate level when a negative pressure containment system is in use.
