What type of transmission-based precaution requires a negative-pressure isolation room?

• A. Contact
• B. Droplet
• C. Airborne
• D. Protective

Answer: (C)

The requirement for a negative-pressure isolation room is associated with airborne transmission-based precautions. This type of precaution is necessary for infections that can be transmitted through the air over long distances, remaining suspended in the air for a period and being inhaled by individuals who are not in direct contact with the infected person. An example of airborne-transmitted infections includes tuberculosis and certain viral infections such as measles.

A negative-pressure room is designed to ensure that air does not flow out of the room to adjacent areas, thus protecting other patients and healthcare workers from potential infectious airborne particles. The air pressure in the room is kept lower than in the surrounding areas, and air is constantly filtered before being released back into the environment. This is crucial for containing airborne pathogens and preventing their spread.

In contrast, contact precautions are typically used for infections that are transmitted via direct contact with the patient or their environment, while droplet precautions are intended for larger respiratory droplets that usually do not travel far and can land on surfaces or directly enter the respiratory pathways of individuals nearby. Protective precautions, also known as reverse or neutropenic precautions, are utilized to protect immunocompromised patients from infections but do not specifically require negative-pressure rooms.
