Answer to Question 1

ANS: C
The patient's current regimen is first-phase treatment. If resistance to streptomycin develops, the provider can change to kanamycin or to ciprofloxacin. Ethambutol is added if there is resistance to isoniazid. Clarithromycin is used during phase II. Renal function tests are not indicated.

Answer to Question 2

ANS: B
The goal is for the patient's sputum test to be negative 2 to 3 months after the therapy. The positive test does not indicate drug resistance. The provider will not change the drugs or keep the patient in the first phase longer than planned.
