Q: All of the following required a monitored negative pressure room isolation except? 

A) Tuberculosis (TB)
B) Varicella 
C) Measles 
D) RSV 
E) Ebola


Answer: D

Airborne isolation requires a meticulous guidelines to follow. Patient should be placed in a monitored negative pressure room with at least 6 to 12 air exchanges per hour. Room exhaust must be appropriately discharged outdoors or passed through a HEPA filter before recirculation within the hospital. In case of TB, a certified respirator must be worn.

Objective of above question is to highlight less known infections which require negative pressure room like varicella, measles, and smallpox. 

On the other hand rubella, mumps, RSV and Influenza require droplet isolation.
