A nurse is educating a client about the risk factors for tuberculosis (TB). Which statement made by the client indicates a correct understanding of the risk factors for TB?

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.

A) Incorrect. Covering the mouth when coughing is important, as it helps prevent the spread of respiratory droplets to others.

B) Correct. Coughing and sneezing into a tissue or the elbow helps contain respiratory droplets and reduces the risk of transmission.

C) Incorrect. Wearing a mask when coughing can be beneficial to prevent the spread of respiratory droplets, especially in crowded settings.

D) Incorrect. Ventilating living spaces by keeping windows and doors open, not closed, helps reduce the concentration of infectious particles in the air.
