一位肺葉切除術後放置胸管的病人，護理師對於引流系統的管理應採取下列何項措施？
A nurse is caring for a client with a chest tube following a lobectomy. Which nursing action is appropriate for the management of the drainage system?
- AStripping the chest tube every 2 hours to maintain patency每兩小時擠壓胸管以維持管路暢通
- BEnsuring the drainage collection device is kept below the level of the patient's chest✓ 正解確保引流收集裝置位於病人胸腔水平之下
- CAdding water to the water-seal chamber every shift每班為水封室加水
- DClamping the chest tube if the system accidentally disconnects若系統意外斷開則夾閉胸管
肺葉切除術（Lobectomy）後放置胸管，主要目的是引流胸膜腔內的血水與氣體，維持肺部擴張。引流裝置必須維持在胸腔水平以下，利用重力與負壓促進引流並防止逆流。夾管會導致張力性氣胸；擠壓管路（Stripping）已證實會產生過大負壓傷害肺組織；補充水封槽水位雖重要，但非預防性動作。維持引流系統的密閉與正確水平，是確保術後呼吸穩定的關鍵。
After a lobectomy, a chest tube is placed primarily to drain blood and air from the pleural space and to maintain lung re-expansion. The drainage device must be kept below the level of the chest, using gravity and negative pressure to promote drainage and prevent reflux. Clamping the tube can cause tension pneumothorax; stripping (squeezing) the tubing has been shown to produce excessive negative pressure and injure lung tissue; and although replenishing water in the water seal chamber is important, it is not a preventive action. Keeping the drainage system closed and at the correct level is key to maintaining respiratory stability after surgery.
