Correct answer: E — Use a spacer and rinse the mouth after each dose
Inhaled corticosteroids can cause local adverse effects such as sore mouth and dysphonia. A spacer improves lung delivery and reduces oropharyngeal deposition, while mouth rinsing reduces local steroid exposure. This is a practical pharmacy intervention before assuming treatment failure.
