Which room type is designed to contain airborne infections and maintain negative pressure?

• A. Standard room
• B. Negative pressure airborne isolation room
• C. Positive pressure private room
• D. Open ward

Answer: (B)

The essential idea is using negative pressure to prevent airborne pathogens from escaping the patient’s room. When a room is kept at negative pressure, air flows into the room rather than out into surrounding areas. This directional airflow helps contain infectious aerosols inside the room and directs contaminated air to be exhausted or filtered before it can reach other parts of the facility. The space is typically sealed and monitored, with dedicated exhaust (often through HEPA filtration) and a required rate of air changes to maintain that negative pressure. Standard rooms have no special airflow direction, so they don’t contain airborne pathogens. A positive-pressure private room pushes air out of the room to protect a vulnerable patient, which would not prevent pathogens from leaving the room if an infection is present. An open ward has no isolation and offers no containment. The negative pressure airborne isolation room is the design intended to contain airborne infections while keeping them from spreading to other areas.
