護理師為老年客戶制定健康促進計畫。下列何者為三級預防活動？
A nurse is creating a health promotion plan for an elderly client. Which of the following is a tertiary prevention activity?
- AEncouraging a well-balanced diet鼓勵均衡飲食
- BFall prevention education跌倒預防教育
- CRegular visual screening定期視力篩檢
- DPhysical therapy for gait improvement✓ 正解改善步態的物理治療
三級預防的核心目標是「復健（Rehabilitation）」與「限制失能（Limitation of Disability）」。當疾病或傷害已經發生，導致功能受損時，透過醫療介入使其恢復功能或防止進一步惡化即屬此範疇。物理治療針對已受損的步態進行訓練，正是為了幫助病人恢復活動能力，避免因長期臥床或步態不穩導致更嚴重的二次傷害。
The core goals of tertiary prevention are rehabilitation and limitation of disability. When disease or injury has already occurred and impaired function, medical interventions aimed at restoring function or preventing further deterioration fall into this category. Physical therapy targeting an already impaired gait is intended precisely to help the client regain mobility and avoid more serious secondary injuries that may result from prolonged bed rest or unsteady gait.
