Question 1 of 5
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?
Correct Answer: D
Rationale: The correct answer is D: Sputum culture for acid-fast bacillus. This test is the most reliable for confirming active pulmonary TB because it directly detects the presence of the Mycobacterium tuberculosis bacteria in the sputum sample. Bronchoscopy (
A) may help visualize the airways but does not definitively confirm TB. Chest X-ray (
B) can show characteristic findings suggestive of TB but cannot confirm the diagnosis. TB skin test (
C) indicates exposure but not active disease. Sputum culture is the gold standard for diagnosing TB, as it allows for definitive identification of the bacteria.
