護理師指導病人使用吸入劑，病人哪些動作顯示技術正確？（選所有適合的）
A nurse is teaching a client about self-administration of an inhaler. Which actions by the client show correct technique? (Select all that apply.)
- AHold the breath for 10 seconds after inhalation✓ 正解吸入後憋氣10秒
- BExhale immediately after the medication enters the mouth藥物進入口腔後立即呼氣
- CExhale completely before using the inhaler✓ 正解使用吸入器前先完全呼氣
- DInhale deeply while spraying the medication✓ 正解噴藥時深層吸入
- EInhale as rapidly as possible while actuating the inhaler按壓吸入器時以最快速度吸氣

正確使用定量噴霧吸入器時，應先充分呼氣，在開始緩慢深吸氣時按壓藥罐，並在吸入後閉氣約 10 秒。快速吸氣會使較多藥物沉積於口咽部，吸入後立即呼氣則會減少藥物留在呼吸道的時間，兩者都會降低治療效果。
Core concept: correct MDI inhaler technique. D (all of the above) is correct because proper MDI use includes: 1) exhale completely before inhalation to make room for medication; 2) press the inhaler as you begin a slow deep breath so medication is carried into the lower airways; 3) hold breath ~10 seconds to allow medication to deposit. All three steps are essential, so A is the right answer. Correct technique maximizes efficacy and minimizes side effects.
