護理師正在指導一位病人首次使用助行器（Walker）。下列哪項指導語是正確的？
A nurse is teaching a client how to use a walker for the first time. Which instruction is correct?
- AMove the walker forward, then step into it with the weaker leg.✓ 正解將助行器向前移動，然後用較弱的那條腿跨入其中。
- BLift the walker and place it down after both feet have moved.雙腳移動後，再提起助行器並放下。
- CLean forward significantly to maintain balance while moving the walker.移動助行器時明顯前傾以保持平衡。
- DStep into the walker with the stronger leg, then move the walker forward.先用較強的那條腿跨入助行器，然後將助行器向前移動。
助行器的正確使用順序是：先將助行器往前推約 15-20 公分，確保四個腳架都穩固著地，接著踏入患肢（弱側），最後再跟上健肢（強側）。這個順序能確保在重心移動最不穩定的時刻，助行器提供了最大的支撐。護理師應指導病人『走入』（Step into）助行器內，而非在助行器後方推行。錯誤選項中，先踏健肢（D）會讓重量在無支撐的情況下壓在患肢；先走再移助行器（B）完全喪失了輔具意義；前傾（C）會改變重心，增加跌倒風險。正確的高度應讓手肘微彎 15-30 度。
The correct sequence for walker use is: first advance the walker forward approximately 15-20 cm, ensuring all four legs are firmly on the ground, then step in with the affected (weaker) leg, and finally bring the unaffected (stronger) leg to follow. This sequence ensures that the walker provides maximum support at the moment when the center of gravity is most unstable. The nurse should instruct the patient to 'step into' the walker rather than pushing it from behind. Among the incorrect options, stepping with the stronger leg first (D) places weight on the weaker leg without support; walking before moving the walker (B) defeats the purpose of the assistive device; leaning forward (C) shifts the center of gravity and increases fall risk. The proper height should allow the elbows to flex 15-30 degrees.
在美國，標準護理常規會強調使用帶輪助行器（Rolling walker）以維持步態連續性，除非平衡極差才用抬起式；台灣則常見使用固定式助行器，且常看到家屬在旁攙扶，這有時會干擾病人建立自主平衡。
