Answer to Question 1

ANS: D
This patient has a moderate risk of tuberculosis; the area of induration would have to be 10 mm or greater to be considered a positive skin test result. Without other clinical signs, there is no indication to treat this patient or to perform diagnostic testing, so a chest x-ray or sputum cultures are not recommended.

Answer to Question 2

ANS: C
Long-term drug therapy is used to prevent reactivation of latent infection that can occur if drugs are withdrawn too soon. Long-term therapy can result in the emergence of drug-resistant organisms, leads to more drug toxicities and side effects, and reduces adherence.
