一位股骨骨折的病人正在進行骨骼牽引。哪項護理措施是正確的？
A client with a fractured femur is in skeletal traction. Which nursing action is appropriate?
- AAllow the knots to touch the pulley to secure the line.讓繩結接觸滑輪以固定線路
- BRemove the weights twice daily for skin care.每天兩次移除重量以進行皮膚護理
- CEnsure the weights hang freely at all times.✓ 正解確保重量始終懸空
- DLift the weights off the floor when repositioning the client.重新安置病人時將重量抬離地面

骨骼牽引（Skeletal traction）的目的是透過持續的機械拉力來復位骨折斷端。為了確保牽引力道的持續性與準確性，牽引用的重量塊必須懸空（Hang freely），不能接觸到地板或床架，否則牽引力會中斷。若發生接觸，牽引即失效，且可能導致骨折部位移位。此外，繩索必須平順通過滑輪，繩結不可卡住滑輪。
In skeletal traction, weights must hang freely at all times to ensure the prescribed force is continuously applied to align the fracture. Interfering with the weights, such as allowing knots to touch pulleys or lifting them during repositioning, disrupts the traction mechanism and can lead to improper bone alignment or muscle spasms.
