A nurse is caring for a client newly diagnosed with active tuberculosis (TB) and prescribed triple antibiotic therapy. The nurse should recognize that which clinical sign indicates inadequate drug therapy after 2 months of treatment?

Positive acid-fast bacilli after 2 months indicates persistent TB bacteria, suggesting inadequate therapy. Other options are less specific to treatment failure.
