Rationale: A. Airborne precautions are required for clients with tuberculosis because Mycobacterium tuberculosis is transmitted via small droplet nuclei that remain suspended in the air. These precautions include a negative-pressure room, use of an N95 respirator, and limiting client transport. B. Droplet precautions are used for larger respiratory droplets (e.g., influenza, meningitis) that travel short distances, not TB. C. Protective precautions are used for immunocompromised clients (e.g., those with neutropenia) to protect them from infection, not for clients with TB. D. Contact precautions are used for infections spread by direct contact (e.g., MRSA, C. difficile), not airborne TB.
