病人術後放置 Jackson-Pratt 引流管，下列何者顯示引流管運作正常？
A client returns from surgery with a Jackson-Pratt drain. Which finding indicates the drain is working properly?
- AThe drain is secured to the client's gown引流管已固定於病人病號服上
- BThe bulb is fully expanded and firm引流球完全擴張且堅硬
- CThe bulb is compressed and expanded引流球壓縮且擴張
- DThe bulb is collapsed and suction is maintained✓ 正解引流球塌陷且維持抽吸力

JP 引流管利用負壓原理（真空）排出傷口積液。當護理師將引流球擠壓排氣後蓋上封口，引流球呈凹陷狀態，代表內部維持負壓。若引流球膨脹，表示負壓消失，無法發揮引流效果，需重新擠壓排氣。此為手術後傷口照護的基本評估技能。
A JP drain uses the principle of negative pressure (vacuum) to evacuate wound fluid. After the nurse compresses the bulb to expel air and caps it, the bulb remains in a collapsed state, indicating that negative pressure is maintained inside. If the bulb expands, it means that the negative pressure has been lost and the drain cannot provide effective drainage, requiring it to be compressed again. This is a basic assessment skill in postoperative wound care.
✦ 台美臨床差異
美方護理教育強調『維持負壓』的概念，台灣臨床常將引流球擠壓視為常規操作，但對負壓概念的定義略有不同。
