護理師評估病人對居家氧氣安全使用的認知。下列哪句話顯示病人需要進一步衛教？
A nurse is evaluating a client's understanding of home oxygen safety. Which statement by the client indicates a need for further teaching?
- AI will keep the oxygen tank at least 6 feet away from gas heaters我會將氧氣鋼瓶放置在距離瓦斯加熱器至少 6 英尺的地方
- BI can use petroleum-based jelly on my lips for dryness✓ 正解我可以在嘴唇上使用凡士林類藥膏來緩解乾燥
- CI will wear cotton clothing to reduce static electricity我會穿著棉質衣物以減少靜電
- DI will place 'No Smoking' signs in my home我會在家中張貼「禁止吸菸」標誌
氧氣具有助燃性（Combustion-supporting），任何油性物質若與氧氣接觸，極易產生化學反應導致自燃。因此，使用氧氣的病人應避免使用凡士林（Petroleum-based）類潤滑劑塗抹唇部或鼻腔，應改用水溶性潤滑劑。其他選項如穿棉質衣物（減少靜電引發火花）、遠離火源及張貼警示，均為居家氧氣安全的基本要求。
Oxygen supports combustion, and any oily substance in contact with oxygen can readily ignite spontaneously through a chemical reaction. Therefore, clients using oxygen should avoid petroleum-based lubricants (such as petroleum jelly) on the lips or nasal passages, and should use water-soluble lubricants instead. The other options—wearing cotton clothing (reducing static electricity that could create sparks), keeping oxygen away from heat sources, and posting warnings—are basic requirements for home oxygen safety.
