Wearing a surgical mask at all times

D.

Avoiding close contact with the client

Answer and Explanation

The Correct Answer is A

B) Incorrect. While handwashing is important for general infection control, it is not the primary measure for preventing TB transmission.

C) Incorrect. Wearing a surgical mask at all times is not sufficient to prevent TB transmission, especially in a healthcare setting.

D) Incorrect. Avoiding close contact with the client is not a practical measure for healthcare professionals providing care to TB patients. Proper isolation measures are more effective.

Correct Answer is C

Explanation

A) Incorrect. Living in well-ventilated areas with good air circulation actually reduces the risk of TB transmission, as TB is an airborne disease.

B) Incorrect. Having a strong immune system can help protect against TB infection, as a compromised immune system increases the risk of developing active TB disease from latent TB infection.

C) Correct. Close contact with someone who has active TB disease is a significant risk factor for TB transmission, as the bacteria can be transmitted through respiratory droplets.

D) Incorrect. While cleanliness and hygiene are important, excessive handwashing alone is not sufficient to prevent TB transmission, as the bacteria are primarily transmitted through the air.
