Answer to Question 1

ANS: B
If there is bacterial resistance to isoniazid, the first phase may be changed to ethambutol, rifampin, and pyrazinamide. Ciprofloxacin, kanamycin, and streptomycin are not generally first-line antitubercular drugs.

Answer to Question 2

ANS: D
Personal contact with a person having a diagnosis of tuberculosis is required to indicate prophylactic treatment with antitubercular therapy. Attending the same school does not necessarily mean close contact occurs. Health care professionals do not need prophylactic treatment. HIV-positive individuals with negative TB skin tests do not need prophylaxis.
