Explanation
Four governing rules Airborne precautions begin when pulmonary TB is suspected. The client wears a mask for source control while the door is closed and AIIR transfer is arranged. Personnel entering use a fit-tested NIOSH-approved N95 or higher-level respirator. Diagnostic evaluation includes at least three sputum specimens 8 to 24 hours apart, with one early-morning specimen, plus NAA testing on at least one respiratory specimen when indicated.
Suspicion is the trigger Infection-control action precedes confirmation. An infection test such as IGRA cannot rule out active pulmonary disease in a symptomatic client.
Source control and worker protection differ The client wears a mask and remains behind a closed door while awaiting AIIR placement. Personnel entering use a fit-tested N95 or higher level of respiratory protection.
Build the diagnostic set At least three sputum specimens are examined at 8-to-24-hour intervals, including one early-morning specimen. NAA testing rapidly detects M. tuberculosis complex but does not replace smear, culture, susceptibility testing, or genotyping.
NCLEX rule Isolate on suspicion; confirm in parallel.
Scenario (Stage 2 — Analyze cues)The nurse translates the symptom, imaging, and exposure pattern into four operational infection-control rules.
Source control — Masking the client to reduce release of infectious material while isolation placement and necessary transport are managed.
Respiratory protection — A fit-tested NIOSH-approved N95 or higher-level respirator used by personnel entering the care space of a client with suspected pulmonary TB.
Nucleic acid amplification test — A rapid test for M. tuberculosis complex on a respiratory specimen that informs management but does not replace smear, culture, and susceptibility testing.
