PN Adult Medical Surgical Practice Exam

Which intervention is appropriate for a client diagnosed with tuberculosis?

1. Place a "no visitors" sign on the client's door.

2. Have the client wear an N95 respiratory mask during transport.

3. Initiate droplet precautions for the client.

4. Place the client in a negative-pressure airflow room.

The correct answer is: Place the client in a negative-pressure airflow room.

A client diagnosed with tuberculosis requires specific interventions to prevent the spread of the disease, which is primarily transmitted through airborne droplets when an infected person coughs or sneezes. Placing the client in a negative-pressure airflow room is crucial because it helps ensure that air flow is directed into the room, rather than being exhausted into the general environment. This minimizes the risk of tuberculosis bacteria being released into surrounding areas, thereby protecting other individuals in the healthcare facility. Airborne precautions, including the use of a negative-pressure room, are essential in managing TB cases, as they help contain the infectious agents. This setup prevents the bacteria from escaping into the atmosphere, thus reducing the risk of transmission to healthcare workers or other patients in the vicinity. It is a critical component of infection control for any patient diagnosed with active tuberculosis. Although the use of an N95 respiratory mask during transport is important and a good practice, the primary control measure is the negative-pressure room, which is more effective in reducing the risk of airborne transmission in the healthcare setting. Other measures such as signs and droplet precautions do not provide the same level of protection needed for airborne pathogens like tuberculosis.
