Correct answer: ASputum including NTM culture, ECG and baseline hearing assessment

Long-term macrolide treatment requires exclusion of NTM and resistant pathogens with sputum culture, assessment of QTc and interacting medicines, and baseline hearing or balance assessment. Starting macrolide monotherapy in unrecognised NTM disease risks selecting macrolide resistance.
