Correct answer: E — Use one puff at a time with slow deep inhalation and consider a spacer

Poor coordination with a pressurised metered-dose inhaler reduces lung deposition. The patient should actuate one puff while inhaling slowly and deeply, and a spacer can improve delivery. Multiple rapid puffs increase oropharyngeal deposition and waste medicine. Boiling or nasal use is inappropriate.
