護理師照護一位使用傑克森-普拉特（Jackson-Pratt）引流管的術後病人。下列何者是維持系統完整性的優先措施？
A nurse is caring for a postoperative client with a Jackson-Pratt drain. Which action is the priority to maintain system integrity?
- ACompress the bulb and secure the plug to establish suction✓ 正解擠壓球體並固定塞子以建立吸引
- BPosition the drain above the level of the incision將引流管置於傷口水平之上
- CEmpty the drain every 4 hours regardless of volume無論引流量多少，每4小時清空引流管
- DIrrigate the drain with sterile saline to prevent clots用無菌生理食鹽水沖洗引流管以防止血塊
— Explanation · 中文詳解 —
JP引流管屬於閉合式負壓引流。護理師清空引流液後，必須擠壓球狀容器排空空氣，重新密封塞子以建立持續性負壓（Negative Pressure）。若無負壓，引流液會積聚在傷口內。其他選項中，無必要頻率清空，不可隨意沖洗，且引流管應放置在低於傷口處以利重力引流。
Compressing the Jackson-Pratt bulb and securing the plug establishes the negative pressure required for effective closed-suction drainage. This action maintains system integrity by ensuring continuous removal of fluid from the surgical site.
✦ 台美臨床差異
美台臨床皆視 JP Drain 為標準術後處置，但在無菌技術操作規範上，美國更強調手部衛生與系統密封性。
