Anticipated: Pyrazinamide: This is a first-line anti-tuberculosis medication used in combination therapy to treat active TB. It helps shorten treatment duration and targets intracellular bacteria. Contact precautions: TB is transmitted via airborne droplets, requiring airborne precautions instead. However, contact precautions can still be implemented in addition to airborne precautions. Ethambutol: This medication is used to prevent resistance and is part of the standard four-drug regimen for active tuberculosis. Isoniazid: A core component of TB treatment, isoniazid is effective against actively dividing Mycobacterium tuberculosis. It is typically given for at least 6 months. Airborne precautions: TB is transmitted through airborne droplets, necessitating airborne precautions such as an N95 mask, negative-pressure isolation, and limiting client transport. Rifampin: Another first-line anti-tuberculosis drug, rifampin works by inhibiting bacterial RNA synthesis and is a crucial part of combination therapy for TB. Contraindicated: Monthly TB skin test for 1 year: Once TB is confirmed via sputum culture and chest x-ray, repeated skin testing is unnecessary and would not provide additional diagnostic value.
