طفل عمره ٩ سنوات عنده ربو، يأخذ بخاخ كورتيزون يومياً، ويسأل لماذا يأخذه وهو بخير. ما الإجابة المناسبة لعمره؟

A 9-year-old with asthma uses a daily steroid inhaler and asks why, since he feels fine. What is an age-appropriate answer?

1. It opens the lungs quickly only during an attack
2. It builds muscles so he can run faster
3. It calms swelling inside the lungs to prevent attacks
4. It is used only when he is unwell

Answer: C) It calms swelling inside the lungs to prevent attacks. Inhaled corticosteroids are preventers that reduce inflammation and are used daily even without symptoms; the reliever (salbutamol) is for attacks.
