評估一位阿茲海默症病人時，哪項症狀最符合初期認知功能退化？
When assessing a client with Alzheimer's disease, which symptom is most consistent with early-stage cognitive decline?
- AInability to recognize family members無法辨識家人
- BForgetting recent events or conversations✓ 正解遺忘近期事件或對話
- CTotal loss of ability to communicate完全喪失溝通能力
- DSevere motor impairment嚴重運動障礙
阿茲海默症（Alzheimer's disease）是一種進行性神經退化疾病。初期病理變化常從海馬迴開始，導致短期記憶喪失，病人容易遺忘近期發生的事件或對話，但對遠期記憶通常保留較好。隨著病程進展，認知功能會持續惡化。在NCLEX臨床思路中，初期症狀辨識有助於早期介入與衛教，而晚期症狀則涉及失能與照護需求增加。此題考驗對疾病分期特徵的掌握。
Alzheimer's disease is a progressive neurodegenerative disorder. The early pathological changes often begin in the hippocampus, leading to short-term memory loss. The client tends to forget recent events or conversations, while remote memory is generally relatively preserved. As the disease progresses, cognitive function continues to deteriorate. In NCLEX-style clinical reasoning, recognizing early symptoms supports early intervention and education, while late-stage symptoms involve increasing functional decline and care needs. This item tests understanding of stage-specific features of the disease.
