Which statement correctly describes room requirements for isolation precautions?

• A. Droplet precautions require a negative pressure room.
• B. Airborne precautions require a negative pressure room and a fit-tested respirator.
• C. Droplet precautions require a normal room with a face shield only.
• D. All isolation types require the same room setup.

Answer: (B)

The main idea is how room pressure and PPE change with different isolation precautions. For airborne precautions, the room must be negative pressure to prevent contaminated air from escaping into adjacent spaces. This setup, along with adequate air exchanges, keeps potentially infectious particles contained. Because these particles are tiny and can linger in the air, anyone entering the room wears a properly fitted respirator (such as an N95 or higher) to protect against inhalation. Droplet precautions involve larger particles that travel only short distances, so they typically use a standard room and require PPE like a surgical mask and eye protection rather than a respirator. The notion that all isolation types use the same room setup isn’t accurate; the room design and required PPE depend on how the infection is transmitted.
