護理師教導 COPD 病人呼吸技巧。哪種技巧最能有效幫助病人排出滯留空氣？
A nurse is teaching a client with COPD about breathing techniques. Which technique is most effective to help the client exhale trapped air?
- AAbdominal breathing腹式呼吸
- BForced coughing用力咳嗽
- CDeep rapid breathing快速深呼吸
- DPursed-lip breathing✓ 正解噘嘴呼吸
— Explanation · 中文詳解 —
COPD 病人常見空氣滯留（Air trapping）。噘嘴式呼吸（Pursed-lip breathing）透過呼氣時製造正壓，維持小氣道開放，讓肺部滯留空氣更有效地排出。深快呼吸會導致過度換氣；用力咳嗽易造成氣道塌陷；腹式呼吸能改善換氣效率但非排氣專用。
Clients with COPD commonly experience air trapping. Pursed-lip breathing creates positive pressure on exhalation that keeps small airways open, allowing trapped air to be exhaled more effectively. Deep rapid breathing leads to hyperventilation; forced coughing can cause airway collapse; and abdominal breathing improves ventilatory efficiency but is not specifically designed to expel trapped air.
