在為長者進行居家安全評估時，下列哪項屬於護理師應識別的環境危害？

跌倒預防（Fall prevention）是高齡護理的核心指標。環境評估的重點在於移除潛在的絆倒危險（Trip hazards）。活動式地毯（Area rugs）因底部摩擦力不足或邊緣捲曲，極易導致長者行走時絆倒，是居家安全評估中最常見應立即排除的危險因子。其他選項均為改善環境安全、預防跌倒的正面措施，而非環境危害。
Fall prevention is a core indicator of geriatric nursing. Environmental assessment focuses on removing potential trip hazards. Area rugs - because of insufficient friction underneath or curled edges - easily cause older adults to trip while walking; they are the most common hazard requiring immediate removal in home safety assessments. The other options are all positive measures to improve environmental safety and prevent falls rather than environmental hazards.
