護理師照護一位使用 Jackson-Pratt 引流管的術後病人。下列哪項措施對確保引流裝置正常運作最重要？
A nurse is caring for a postoperative client with a Jackson-Pratt drain. Which action is most important to ensure proper functioning of the device?
- ACompress the reservoir and re-establish suction✓ 正解挤压储液囊并恢复负压吸引
- BMaintain the drain below the level of the surgical site保持引流管低于手术部位
- CChange the dressing around the insertion site daily每天更换插入点周围的敷料
- DFlush the tubing with sterile saline every 4 hours每 4 小时用无菌生理盐水冲洗管路
Jackson-Pratt 屬於密閉式負壓引流，維持負壓是引流液排出關鍵。術後引流後需將容器擠壓排氣並關閉蓋子，以維持負壓狀態。若容器膨脹則無負壓，無法達到引流效用。A 是重力引流裝置（如 Penrose）的重點；D 會增加感染風險；D 為常規照護但非維持功能的關鍵。
A Jackson-Pratt drain is a closed-system negative-pressure drain, and maintaining negative pressure is the key to fluid evacuation. After emptying the reservoir, the nurse must compress it to expel air and close the cap to re-establish suction. If the reservoir is expanded, no negative pressure exists and the drain cannot function. Option B applies to gravity drainage devices (such as a Penrose drain); C increases the risk of infection; C is routine care but not the critical action for maintaining drain function.
美台兩地在 JP 引流管的維護邏輯一致，均強調負壓維持與觀察引流液特徵。
