مريض سل رئوي إيجابي البلغم بدأ العلاج منذ ٣ أسابيع، وأعراضه تحسنت. متى يمكن غالباً إيقاف العزل الهوائي في المستشفى؟

A smear-positive TB client started treatment 3 weeks ago and has improved. When can hospital airborne isolation usually stop?

1. After three negative smears with clear improvement
2. Once the fever settles, without sputum testing
3. Only when the full six-month course has been completed
4. After 3 days of treatment whatever the results

Answer: A) After three negative smears with clear improvement. Isolation usually stops when the client is on effective therapy for an adequate period, clinically improved, with three consecutive negative smears, per infection-control policy. Drug-resistant TB has stricter criteria.
