The nurse is providing discharge teaching to a client diagnosed with tuberculosis. Which statement by the client with tuberculosis indicates a need for further teaching?

Choice A rationale Tuberculosis is caused by Mycobacterium tuberculosis and is transmitted through airborne droplets. Covering the mouth when coughing, sneezing, or talking is a critical infection control measure to prevent the aerosolization of these bacilli into the environment. This action significantly reduces the risk of transmission to healthcare workers and family members. This client statement reflects a correct understanding of how to protect others from respiratory droplets containing the infectious bacteria. Choice B rationale Because tuberculosis is highly contagious through the air, close contacts of an infected individual, such as family members, are at high risk for latent or active infection. Testing is essential for early detection and treatment to prevent further community spread. Public health guidelines mandate contact tracing for anyone living in the same household. This statement shows the client understands the necessity of screening those who have been exposed to the primary infection source. Choice C rationale This statement indicates a need for further teaching because tuberculosis treatment requires a long-term commitment, often lasting six to nine months. Stopping medication early leads to treatment failure and the development of multidrug-resistant tuberculosis strains. Even if the patient feels better as the bacterial load decreases, some dormant bacilli remain. Complete eradication of the infection is only possible by finishing the entire prescribed course of antibiotics, such as isoniazid and rifampin. Choice D rationale Wearing a mask in public places is a standard precaution for patients with active, infectious tuberculosis to prevent spreading the bacteria to the general population. While the patient is still considered infectious, usually until they have had several weeks of treatment and negative sputum smears, the mask acts as a barrier for respiratory secretions. This indicates the client recognizes their responsibility to minimize public health risks until a physician confirms they are no longer contagious.
