Airborne precautions are the BEST initial action for a suspected tuberculosis case. TB is transmitted through airborne droplet nuclei, and proper isolation is crucial to prevent spread. While obtaining a sputum sample is important for diagnosis, it's not the first step. Administering antibiotics or notifying the health department are premature actions before confirming the diagnosis. Airborne precautions include placing the patient in a negative pressure room, using N95 respirators for healthcare workers, and limiting patient movement outside the room. This protects other patients, staff, and visitors from potential exposure while further diagnostic steps are taken.
