為了預防術後病人感染，護理師應優先採取哪項措施？
Which action should the nurse prioritize to prevent infection in a postoperative client?
- AChange the surgical dressing every 4 hours每4小時更換手術敷料
- BAdminister prophylactic antibiotics at the scheduled time按時給予預防性抗生素
- CPerform thorough hand hygiene before touching the dressing✓ 正解接觸敷料前徹底執行手部衛生
- DEncourage the client to increase fluid intake鼓勵個案增加液體攝取量
預防術後感染（Postoperative infection）最有效且最簡單的措施是「洗手」。洗手是感染控制的黃金準則，能有效阻斷病原體透過醫護人員的手部傳播給術後易感病人。雖然抗生素與敷料更換很重要，但洗手是所有護理行為前的先決條件。臨床上，護理師在接觸任何傷口敷料前，必須嚴格執行手部衛生，這是防範外源性感染的核心。
The most effective and simplest measure to prevent postoperative infection is hand hygiene. Hand washing is the gold standard of infection control, effectively interrupting transmission of pathogens from healthcare workers to vulnerable postoperative clients. While antibiotics and dressing changes are important, hand hygiene is a prerequisite for all nursing actions. Clinically, the nurse must perform strict hand hygiene before touching any wound dressing; this is the core defense against exogenous infection.
