A nurse is providing discharge teaching about disease prevention to a client who has active tuberculosis. Which of the following should the nurse include?

A. Educating the client how to cover nose and mouth with tissues when coughing: Covering the nose and mouth helps prevent airborne transmission of Mycobacterium tuberculosis. Proper disposal of tissues and hand hygiene further reduce the risk of spreading the infection to others. B. Recommending the client may return to work after two negative sputum cultures: Returning to work should only be considered after the client is no longer contagious and cleared by the healthcare provider. This often requires multiple negative sputum cultures and clinical evaluation, not just a time-based recommendation. C. Instructing the client that he is no longer contagious after 1 week of medication therapy: Clients with active TB are not automatically non-contagious after one week of therapy. Contagiousness decreases gradually, and adherence to medication and follow-up sputum tests determine when the client is safe to interact with others. D. Teaching the client’s family to wear protective masks while with the client: Family members do not routinely need masks if proper airborne precautions are in place and the client is receiving treatment at home. Emphasis should be on client respiratory hygiene, ventilation, and adherence to treatment.
