Correct answer: D — Polysomnography or specialist sleep assessment before definitive treatment

Witnessed apnoeas and daytime symptoms suggest obstructive sleep apnoea; polysomnography or sleep specialist assessment helps define severity and guide adenotonsillectomy decisions. Asthma monitoring does not assess upper-airway obstruction during sleep. The pearl is that behavioural symptoms may be a presenting feature of paediatric sleep-disordered breathing.
