A nurse is caring for a client who has active tuberculosis. Which of the following interventions should the nurse include in the plan of care?

A. Wear a high-efficiency particulate air mask: Clients with active tuberculosis require airborne precautions because TB is transmitted through small droplet nuclei that remain suspended in the air. Wearing a high-efficiency particulate air mask (N95 respirator) protects the nurse from inhaling infectious particles during care. B. Obtain daily sputum specimens: Daily sputum specimens are not required for active TB. Sputum samples are obtained for initial diagnosis and then collected monthly until three consecutive negative results confirm noninfectious status. Collecting them daily would not provide additional benefit and is not part of routine care. C. Perform chest percussion twice daily: Chest percussion is not a standard intervention for tuberculosis management. TB treatment focuses on airborne isolation, medication adherence, and monitoring response to therapy. Percussion would not improve outcomes or address the primary concerns of infection control and drug therapy. D. Initiate droplet precautions: Droplet precautions are used for larger respiratory droplets that travel short distances, such as those from influenza or meningitis. TB requires airborne precautions due to its ability to remain suspended in air for prolonged periods.
