Qstream Annual Recurring Revenue (ARR) Practice Test

TB spreads through airborne particles, so preventing transmission hinges on combining isolation, containment, and protection for staff. Placing the patient in a negative-pressure Airborne Infection Isolation Room creates a controlled environment where air flows into the room and is vented safely, reducing the chance that infectious aerosols escape to other areas. Having the patient wear a surgical mask whenever they must leave the room adds a layer of source control, lowering the amount of infectious particles released into the surrounding air. For anyone entering the room, using a NIOSH-approved N95 respirator or a powered air-purifying respirator provides robust personal protection against inhaling airborne TB bacteria. Because each measure targets a different point of exposure—preventing spread from the patient, containing aerosols in the environment, and protecting healthcare workers—the combined approach is the most effective and is the recommended standard for suspected TB.
