護理師教導病人如何預防手術部位感染（SSIs），應包含哪些指示？（選所有適合的）

核心概念：手術部位感染（Surgical Site Infections, SSIs）是手術後常見的併發症之一，可能延遲傷口癒合、增加住院天數，甚至導致嚴重後果。預防 SSI 需要術前、術中和術後多方面的綜合措施。 為何正確答案 A, B, C, D 對： A. 術前按時服用抗生素（antibiotics）能幫助清除手術區域可能存在的細菌，降低感染風險。術後持續服用（若醫囑有）則用於預防術中可能發生的感染。 B. 術前使用抗菌皂（antimicrobial soap）沐浴，能顯著減少皮膚上的細菌數量，是降低 SSI 風險的有效方法。 C. 保持手術傷口清潔乾燥（keep the surgical incision clean and dry）是預防感染的基本原則。避免潮濕和污垢堆積，能減少細菌滋生的機會。 D. 避免用未洗淨的手觸摸傷口（avoid touching the incision site with unwashed hands）是防止外來病原體污染傷口的關鍵。手部衛生是預防交叉感染的基礎。 為何選項 E 錯：非必要不頻繁更換手術敷料（dressing）。過於頻繁地更換敷料，尤其是在傷口乾燥、清潔且無滲液的情況下，反而會增加傷口暴露於空氣和潛在污染源的機會，提高感染風險。敷料更換應根據醫囑或臨床評估（如敷料濕掉、脫落或有滲液時）進行。 臨床思路（Safety / Infection Control）：此題涵蓋了 SSI 預防的幾個關鍵面向。從術前準備到術後照護，每個環節都對預防感染至關重要。選項 E 的錯誤在於不恰當的頻率，反而可能增加風險。

Core concept: Surgical Site Infections (SSIs) are one of the most common postoperative complications. They can delay wound healing, prolong hospitalization, and even cause serious consequences. Prevention of SSIs requires comprehensive measures before, during, and after surgery. Why the correct answers (A, B, C, D) are right: A. Taking prescribed antibiotics on schedule before surgery helps clear bacteria that may be present at the surgical site, reducing the risk of infection. Continuing them postoperatively (if ordered) addresses any infections that may have developed intraoperatively. B. Showering with antimicrobial soap before surgery significantly reduces the bacterial load on the skin and is an effective way to reduce SSI risk. C. Keeping the surgical incision clean and dry is a basic principle of infection prevention. Avoiding moisture and debris reduces opportunities for bacterial growth. D. Avoiding touching the incision with unwashed hands is a key way to prevent introducing external pathogens. Hand hygiene is the foundation of cross-infection prevention. Why E is wrong: Routine changing of surgical dressings without clinical necessity is not advisable. Frequent dressing changes - especially when the wound is dry, clean, and without drainage - increase exposure of the wound to air and potential sources of contamination, thereby increasing the risk of infection. Dressings should be changed according to orders or clinical assessment (such as when the dressing is wet, loose, or soiled). Clinical reasoning (Safety / Infection Control): This question covers several key aspects of SSI prevention. From preoperative preparation to postoperative care, every step matters for infection prevention. Option E is wrong because of inappropriate frequency, which may actually increase risk.

預防手術部位感染（SSIs）的原則在美國和台灣的醫療體系中是高度一致的，都遵循 CDC 和 WHO 的相關指引。包括術前抗生素使用、皮膚準備、術中無菌操作、術後傷口照護等。美國在數據監測和實證醫學的應用上可能更為廣泛，例如有專門的 SSI 預防工具包（bundle）。台灣的醫院也普遍執行這些措施，並有感染管制部門進行監測。
