護理師正在照顧一位有跌倒病史的病人。該病人被處方一種可能引起頭暈的新藥物。下列哪項介入措施最重要？
A nurse is caring for a client with a history of falls. The client is prescribed a new medication that can cause dizziness. Which intervention is most important to implement?
- AAssist the client with ambulation協助病人行走
- BEnsure the call light is within reach確保呼叫鈴在觸手可及之處
- CAssess the client's gait and balance評估病人的步態與平衡能力
- DEducate the client on potential side effects✓ 正解教育病人潛在的副作用
護理核心在於「風險預防」。當病人使用可能引發頭暈的新藥物時，教育病人了解副作用是預防跌倒的根本策略。病人若能認知到藥物帶來的生理變化（如姿勢性低血壓），就能主動採取預防措施（如緩慢起身、尋求協助），這是最有效的自我防護方式。其他選項雖為跌倒預防的一環，但屬環境安全或輔助措施，教育病人才是賦能病人參與自身安全的關鍵。
The core of nursing care is risk prevention. When a client begins a new medication that may cause dizziness, educating the client about side effects is the fundamental strategy for fall prevention. If the client is aware of the physiologic changes the medication may produce (such as orthostatic hypotension), they can take proactive measures (such as standing up slowly or seeking assistance), which is the most effective form of self-protection. The other options are part of fall prevention but represent environmental safety or auxiliary measures; client education is what empowers the client to participate actively in their own safety.
