護理師正在照顧一位嚴重燒傷的病人。該病人有高感染風險。下列哪項護理措施對預防感染最為關鍵？
A nurse is caring for a client with a severe burn injury. The client is at high risk for infection. Which nursing intervention is most critical for preventing infection?
- AEncourage adequate protein intake鼓勵攝取充足的蛋白質
- BMonitor vital signs frequently頻繁監測生命徵象
- CAdminister prophylactic antibiotics給予預防性抗生素
- DMaintain strict aseptic technique during wound care✓ 正解在傷口護理期間維持嚴格的無菌技術
嚴重燒傷病人因皮膚屏障受損，導致體液流失與感染風險極高，感染是導致燒傷病人死亡的主要原因之一。在臨床護理中，預防感染的核心在於阻斷細菌接觸傷口。嚴格無菌技術（Strict Aseptic Technique）是預防外源性感染最關鍵的護理介入，能確保操作過程不將微生物引入傷口。相較於藥物預防或營養補充，物理性的防護是防止病原體入侵最直接且有效的手段，符合感染控制的首要原則。
Clients with severe burns have damaged skin barriers, resulting in fluid loss and extremely high infection risk; infection is one of the leading causes of death in burn patients. In clinical nursing, the core of infection prevention is blocking bacterial contact with the wound. Strict aseptic technique is the most critical nursing intervention for preventing exogenous infection, ensuring that microorganisms are not introduced into the wound during care procedures. Compared with pharmacological prophylaxis or nutritional support, physical protection is the most direct and effective means of preventing pathogen invasion and aligns with the foremost principle of infection control.
美國燒傷中心（Burn Center）對於無菌技術的要求極為嚴格，通常執行時會穿戴全套無菌隔離衣，且傷口處理常由受過專門訓練的燒傷護理師執行，與台灣一般外科病房的處置強度可能有細微差異。
