護理師協助一位手術後第一次嘗試坐在床緣的行動不便病人。為確保安全，下列哪項措施最重要？
A nurse is preparing to assist a client with limited mobility to sit at the edge of the bed for the first time after surgery. Which action should the nurse prioritize to ensure client safety?
- ADangle the client's legs at the bedside for a few minutes✓ 正解讓病人雙腿在床緣懸垂幾分鐘
- BCall another nurse to assist with the transfer呼叫另一位護理師協助轉移
- CApply non-slip socks to the client's feet為病人穿上防滑襪
- DEnsure the bed is in the lowest position before starting在開始前確保病床處於最低位置
術後病人因長期臥床、麻醉藥物影響及血管容量變化，首次下床時極易發生姿勢性低血壓（Orthostatic Hypotension）。「床緣坐位（Dangling）」的臨床意義在於讓病人有時間適應重力變化，同時透過下肢活動促使血液回流，預防腦部缺氧與暈厥。這是所有下床活動前的安全準則，能有效降低跌倒風險。
Postoperative clients are highly susceptible to orthostatic hypotension on first ambulation because of prolonged bed rest, the effects of anesthetic agents, and changes in vascular volume. The clinical purpose of dangling (sitting on the edge of the bed) is to allow the client time to adapt to the change in gravity while leg movement promotes venous return, preventing cerebral hypoxia and syncope. This is a safety standard before any out-of-bed activity and effectively reduces fall risk.
