Which barrier precautions does a Protective Environment add beyond Standard and Transmission-Based Precautions?
ADouble gloving for every entry into the room
BA gown and gloves for every entry to the room
CA respirator for every person entering the room
DNone beyond those already indicated for the patient
Answer & Solution
Correct answer: D. None beyond those already indicated for the patient
1. A Protective Environment is built from engineering controls: filtered air, directed airflow, positive pressure, sealed rooms and dust control.
2. It does not include the use of barrier precautions beyond those already indicated for Standard and Transmission-Based Precautions.
3. So gowning or gloving every visitor is not what the environment adds.
4. A respirator for everyone entering would protect the wearer, while this environment is built to protect the patient.
