A nurse is planning care for a client who has tuberculosis. Which of the following precautions should the nurse implement for this client?

Rationale: A. Contact precautions: Contact precautions are used for infections spread by direct or indirect contact, such as Clostridioides difficile or MRSA. Tuberculosis is transmitted through airborne particles, not contact. B. Protective environment precautions: Protective environments are for immunocompromised clients, such as those undergoing stem cell transplants, to protect them from external infections. This does not apply to clients with active infections like tuberculosis. C. Droplet precautions: Droplet precautions are used for infections spread through large respiratory droplets, like influenza or pertussis. Tuberculosis is spread via much smaller airborne particles that remain suspended in the air. D. Airborne precautions: Airborne precautions are required for tuberculosis because it is spread through tiny airborne droplets. These precautions include placing the client in a negative pressure room and having staff wear an N95 respirator when entering the room.
