A nurse is caring for a client who has a history of exposure to TB and symptoms of night sweats and hemoptysis. Which of the following tests should the nurse realize is the most reliable to confirm the diagnosis of active pulmonary TB?
Mantoux test
Sputum culture for acid-fast bacillus
Sputum smear
Chest x-ray
The Correct Answer is B
This is because sputum culture can identify the presence and type of mycobacteria that cause TB, while other tests can only indicate exposure or infection. Sputum culture results may take several weeks, so treatment should be initiated based on clinical suspicion and other tests.
