What does a positive PPD test indicate?
A. The client is presently in the active phase of Tuberculosis
B. The client is presently in the latent phase of Tuberculosis
C. The client is presently or has previously been infected with Tuberculosis
D. None of the above
Rational: A positive PPD does not distinguish between active and latent TB disease, it only indicates that the person is presently or has previously been infected with tuberculosis bacteria. The next step would be that other tests would be ordered, such as a chest x-ray and a sample of sputum to determine whether the person has active TB disease.
