📒 The 1-minute cheat sheet
📌 Precautions
Airborne: negative-pressure room
N95 respirator (fit-tested)
Pt wears surgical mask if transported
🩺 Signs
Night sweats, hemoptysis, wt loss
Chronic cough, low-grade fever
📌 Dx
Confirm: 3 sputum AFB cultures
+PPD ≥ 10mm; gold standard culture
🧪 Meds
RIPE x6-9 mo: rifampin, INH, PZA, ethambutol
INH → B6 for neuropathy; orange fluids = rifampin
📚 Tuberculosis Precautions — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Tuberculosis is caused by Mycobacterium tuberculosis, an airborne organism spread through inhaled droplet nuclei that primarily infects the lungs. Active pulmonary TB requires airborne precautions because the bacteria stay suspended in air. Latent TB is non-infectious and asymptomatic but can reactivate. Treatment is long-term multidrug therapy, and strict adherence is essential to cure and to prevent drug resistance.
🔑
Key points
Understand these first
Classic symptoms are a chronic productive cough lasting over three weeks, hemoptysis, night sweats, low-grade fever, fatigue, and weight loss.
TB spreads by airborne droplet nuclei, so active cases need a negative-pressure room and N95 respirators for staff.
A positive PPD/Mantoux or IGRA shows exposure; a chest x-ray and sputum AFB cultures confirm active disease.
Standard therapy is months of combined drugs, classically Rifampin, Isoniazid, Pyrazinamide, and Ethambutol (RIPE).
The patient is considered noninfectious after adequate treatment yields three consecutive negative sputum AFB smears.
Rifampin turns body fluids (urine, sweat, tears) orange-red, and isoniazid can cause peripheral neuropathy and hepatotoxicity.
✅
Nursing priorities
What to do, in order
Place the patient in a negative-pressure (airborne isolation) room and keep the door closed.
Wear a fit-tested N95 respirator before entering; have the patient wear a surgical mask when transported.
Administer multidrug therapy on schedule and use directly observed therapy (DOT) to ensure adherence.
Collect sputum specimens for AFB smear and culture as ordered to track infectiousness.
Monitor liver function and give vitamin B6 (pyridoxine) with isoniazid to prevent neuropathy.
🚩
Red flags — report now
Escalate immediately
Never enter the room of an active TB patient without a fit-tested N95 respirator.
Jaundice, dark urine, right-upper-quadrant pain, or rising liver enzymes signal drug hepatotoxicity and must be reported.
Hemoptysis with respiratory distress requires urgent evaluation.
Nonadherence to therapy must be addressed immediately because it breeds multidrug-resistant TB.

Labs & values
Numbers to know
PPD/Mantoux positive at varying induration thresholds (5/10/15 mm depending on risk)
Sputum acid-fast bacilli (AFB) smear/culture confirms active TB
AST/ALT monitored for hepatotoxicity (normal AST ~10-40, ALT ~7-56 units/L)
🗣️
Patient teaching
What patients must know
Take all TB medications exactly as prescribed for the full course (months) even after feeling well, to cure infection and prevent resistance.
Cover the mouth when coughing, wear a mask in public until cleared, and ensure household contacts get tested.
Expect rifampin to turn urine and tears orange, avoid alcohol due to liver risk, and keep all sputum and clinic follow-ups.
❓ Tuberculosis Precautions: NCLEX FAQs
What are the priority nursing interventions for Tuberculosis Precautions?
Place the patient in a negative-pressure (airborne isolation) room and keep the door closed. Wear a fit-tested N95 respirator before entering; have the patient wear a surgical mask when transported. Administer multidrug therapy on schedule and use directly observed therapy (DOT) to ensure adherence. Collect sputum specimens for AFB smear and culture as ordered to track infectiousness.
What are the warning signs of Tuberculosis Precautions a nurse must report?
Never enter the room of an active TB patient without a fit-tested N95 respirator. Jaundice, dark urine, right-upper-quadrant pain, or rising liver enzymes signal drug hepatotoxicity and must be reported. Hemoptysis with respiratory distress requires urgent evaluation. Nonadherence to therapy must be addressed immediately because it breeds multidrug-resistant TB.
