一位病人因檢查禁食，護理師採取哪項措施最能確保病人舒適？
A nurse is caring for a client who is NPO for a procedure. What is the most appropriate action for the nurse to perform to ensure client comfort?
- AOffer the client sugar-free gum提供無糖口香糖
- BDim the lights to decrease appetite調暗燈光以降低食慾
- CApply lip balm to prevent chapping塗抹潤唇膏以防止乾裂
- DProvide frequent mouth care✓ 正解提供頻繁的口腔護理
針對禁食（NPO）病人，護理核心在於緩解因無法攝取水分而引發的口黏膜乾燥與不適。頻繁口腔護理不僅能維持衛生，還能透過濕潤口腔黏膜提升舒適感，這是護理師在執行醫囑期間能直接提供的基本舒適護理。其他選項如嚼口香糖會刺激胃液分泌，違反禁食原意；潤唇膏雖能緩解嘴唇乾裂，但對口腔內的乾燥感改善有限，故非優先選擇。
For an NPO client, the central nursing focus is to relieve oral mucosal dryness and discomfort caused by the inability to take in fluids. Frequent mouth care not only maintains hygiene but also moistens the oral mucosa and improves comfort; it is a fundamental comfort measure that the nurse can directly provide while implementing the medical order. Among the other options, chewing gum stimulates gastric secretions and contradicts the purpose of NPO; lip balm can ease lip dryness but has limited effect on the dryness inside the mouth, so it is not the priority choice.
