護理師照護一位嚴重燒傷的病人，下列哪項護理措施最能預防感染？
A nurse is managing a client with severe burns. Which nursing intervention is MOST critical for preventing infection?
- AApply topical antimicrobial agents塗抹局部抗菌劑
- BUse sterile technique during wound care✓ 正解在傷口護理期間使用無菌技術
- CAdminister analgesics給予止痛藥
- DEncourage adequate fluid intake鼓勵攝取充足的液體
嚴重燒傷導致皮膚屏障受損，病人極易發生全身性感染。無菌技術（Sterile Technique）是預防外源性病原體入侵傷口的最直接且關鍵的手段。在進行任何傷口清創或換藥操作時，嚴格遵守無菌操作不僅能保護傷口，還能防止交叉感染。雖然其他選項（止痛、補液）對於整體病人的穩定很重要，但就「預防感染」這一目標而言，無菌技術是護理師能直接執行的最強效手段。
Severe burns disrupt the skin barrier, leaving the client highly susceptible to systemic infection. Sterile technique is the most direct and critical means of preventing exogenous pathogens from entering the wound. During any wound debridement or dressing change, strict aseptic technique not only protects the wound but also prevents cross-contamination. Although the other options (analgesia, fluid replacement) are important for overall patient stability, when the goal is 'preventing infection,' sterile technique is the most powerful intervention the nurse can directly perform.
