Question 1 of 5
The nurse determines that a tuberculin skin test is positive. Which diagnostic test should the nurse anticipate will be prescribed to confirm a diagnosis tuberculosis (TB)?
Correct Answer: B
Rationale: Although the findings of the chest x-ray examination are important, it is not possible to make a diagnosis of TB solely on the basis of this examination because other diseases can mimic the appearance of TB. The demonstration of tubercle bacilli bacteriologically is essential for establishing a diagnosis. The microscopic examination of sputum for acid-fast bacilli is usually the first bacteriological evidence of the presence of tubercle bacilli. Options 3 and 4 will not diagnose TB.
