護理師向病人進行氧氣使用安全衛教。下列哪項敘述顯示病人需要進一步指導？
A nurse is educating a client about safe use of oxygen. Which statement indicates the need for further teaching?
- AI will wear cotton clothing to prevent static electricity我會穿棉質衣物以防止靜電
- BI will keep the oxygen tank secured in a rack我會將氧氣鋼瓶固定在架子上
- CI can use petroleum jelly on my lips for dryness✓ 正解我可以在嘴唇上塗抹凡士林以緩解乾燥
- DI will not smoke near the oxygen equipment我不會在氧氣設備附近吸菸
氧氣使用安全的核心在於「禁火」與「避免助燃」。凡士林（Petroleum jelly）屬於石油基潤滑劑，其成分為油性，若接觸到高濃度氧氣，極易發生燃燒。護理師必須教導病人使用水溶性（Water-soluble）潤滑劑來緩解鼻黏膜乾燥，而非油性產品。此外，其他選項皆為正確的安全實務，如減少靜電、固定鋼瓶與嚴禁吸菸。
The core of oxygen safety is preventing fire and avoiding flammable substances. Petroleum jelly is a petroleum-based lubricant whose oily composition can easily ignite when it contacts high-concentration oxygen. The nurse must teach the client to use water-soluble lubricants to relieve nasal mucosal dryness rather than oil-based products. In addition, the other options are correct safety practices, such as reducing static electricity, securing oxygen cylinders, and strictly prohibiting smoking.
