Which infection control precautions are appropriate for a client with active tuberculosis (TB)?

Transmission-based precautions for NCLEX-PN: (1) AIRBORNE — for organisms transmitted by very small droplet nuclei suspended in air: TB, measles, varicella (chickenpox), disseminated zoster, COVID-19 in high-risk procedures, SARS, MERS. Requires: private NEGATIVE-PRESSURE room with door closed, N95 respirator (fit-tested) for all staff entering, client wears surgical mask when transported. (2) DROPLET — for larger droplets traveling shorter distances: influenza, pertussis (whooping cough), mumps, rubella, meningococcal infections, group A strep. Requires: private room (or cohort), surgical mask within 3-6 feet, client wears surgical mask when transported. (3) CONTACT — for direct or indirect contact with skin/wounds/surfaces: C. difficile, MRSA, VRE, scabies, RSV, hepatitis A in diapered patients. Requires: gown and gloves on entry, dedicated equipment, hand hygiene with soap and water for C. diff (alcohol-based sanitizer doesn't kill C. diff spores). Standard precautions apply to ALL clients regardless of diagnosis: hand hygiene, gloves when contacting body fluids, mask/eye protection if splashing risk. Memorize the categories and which organisms fit each — heavily tested on NCLEX.
