護理師指導病人居家氧氣治療，出現哪些行為時需介入指導？（選所有適合的）
A nurse is teaching a client about discharge planning for home oxygen therapy. Which client behaviors indicate that the nurse should intervene? (Select all that apply.)
- AThe client places a 'No Smoking' sign on the bedroom door病人在臥室門上貼上「禁止吸菸」標示。
- BThe client uses an oil-based lubricant on the nares for dryness✓ 正解病人為緩解鼻孔乾燥使用油性潤滑劑。
- CThe client stores spare oxygen cylinders in a hallway closet✓ 正解病人將備用氧氣鋼瓶存放在走廊衣櫃內。
- DThe client adjusts the flow rate to 6 L/min when feeling short of breath✓ 正解病人感到呼吸困難時將流量調整為 6 L/min。
- EThe client checks the oxygen tubing for kinks before sitting down病人在坐下前檢查氧氣管路有無折疊。
居家氧氣安全禁忌：油脂（如凡士林）與氧氣接觸有燃燒風險，鼻黏膜乾燥應選水溶性乳液。氧氣瓶不能密閉存放，需防碰撞翻倒。擅自調高氧流量未經醫師評估，若病人為 COPD 可能引發 CO2 滯留。A 為正確安全行為；E 確保氣流通暢是正確習慣。
Home oxygen safety contraindications: oils (such as petroleum jelly) in contact with oxygen carry a fire/combustion risk; for dry nasal mucosa, water-soluble lubricants should be used. Oxygen cylinders must not be stored enclosed and must be protected from being knocked over. Adjusting the oxygen flow rate upward without a physician's evaluation may, in clients with COPD, precipitate CO2 retention. A is a correct safety behavior; E, checking that the tubing remains patent, is a correct habit.
美國有完善的居護師系統協助安全查核，台灣多依賴家屬執行，衛教深度與頻率需更高。
