護理師監督一名護理助理（UAP）協助新做髖關節置換術的病人從床轉移至椅子。下列哪項觀察需要護理師立即介入？
A nurse is supervising an unlicensed assistive personnel (UAP) who is assisting a client with a new hip replacement in transferring from bed to chair. Which observation requires immediate intervention by the nurse?
- AThe UAP allows the client to pivot on the operative leg✓ 正解護理助理允許病人以手術腿為軸心旋轉
- BThe UAP positions the chair on the client's unaffected side護理助理將椅子放置在病人未受損的一侧
- CThe UAP instructs the client to keep the affected hip at a 45-degree angle護理助理指示病人將患側髖關節保持在45度角
- DThe UAP applies a gait belt around the client's waist護理助理在病人腰部綁上步態帶
髖關節置換術（Total Hip Arthroplasty, THA）後的病人必須嚴格遵循髖關節預防脫位（Dislocation）的原則。核心限制包括：避免屈髖大於 90 度、避免患側內收（Adduction）以及避免患側進行旋轉（Pivot）動作。若允許病人以患肢為支點旋轉，會給予人工髖關節過大的扭力，導致脫位。護理師必須立即介入並糾正此類危險動作。
After a Total Hip Arthroplasty (THA), clients must strictly adhere to hip dislocation precautions. The key restrictions are: avoid hip flexion greater than 90 degrees, avoid adduction of the operative leg, and avoid pivoting (rotation) on the operative leg. Allowing the client to pivot on the operative limb places excessive torque on the prosthesis and can result in dislocation. The nurse must intervene immediately to correct such a dangerous maneuver.
