護理師照護一位使用攜帶式傷口引流裝置的術後病人，下列哪項措施能確保裝置正確運作？
A nurse is caring for a postoperative client who has a portable wound suction device. Which action is the priority to ensure the device functions correctly?
- AEmpty the container every 8 hours regardless of the amount無論引流量多少，每 8 小時排空一次容器
- BMaintain the drainage container below the level of the surgical site保持引流容器低於手術部位
- CEnsure the vacuum is activated by collapsing the reservoir✓ 正解透過壓縮儲液囊來啟動真空
- DIrrigate the tubing with sterile normal saline to prevent clots用無菌生理食鹽水沖洗管路以防止血塊

攜帶式傷口引流器（如 Hemovac 或 Jackson-Pratt）依賴負壓運作。若未擠壓儲存器至扁平狀，則無法產生吸引力，導致引流液堆積在傷口空間。維持低位是為了預防逆流，但維持負壓才是確保引流抽吸功能的核心步驟。
A portable wound suction device (such as a Hemovac or Jackson-Pratt) operates on negative pressure. If the reservoir is not compressed flat, suction cannot be generated and drainage will accumulate in the wound space. Keeping the device below the wound prevents backflow, but maintaining the vacuum is the core step that ensures the device's suctioning function.
✦ 台美臨床差異
美國護理師依 protocol 維護引流，台灣病房則強調醫師醫囑，且對負壓球的擠壓技術指導較細緻。
