對於輕度阿茲海默症患者，下列哪項活動最能協助維持認知功能？
Which of the following activities is most appropriate for a client with early-stage Alzheimer's disease to maintain cognitive function?
- AListening to background music聆聽背景音樂
- BSleeping during the day白天睡覺
- CEngaging in simple puzzle games✓ 正解參與簡單的拼圖遊戲
- DWatching television programs觀看電視節目
輕度阿茲海默症（Alzheimer's disease）患者的核心護理目標是延緩認知功能衰退，並維持病人的生活品質。臨床上，透過結構化、具備適度認知挑戰的活動（Cognitive stimulation）能刺激神經突觸，維持大腦功能。拼圖遊戲需要邏輯推理、視覺空間感及短期記憶，能提供有效的腦部訓練。相比之下，被動性活動效果較差，而混亂的生活作息則會加劇病人的認知混亂。
The core nursing goal for patients with early-stage Alzheimer's disease is to delay cognitive decline and maintain quality of life. Clinically, structured activities with appropriate cognitive challenge (cognitive stimulation) can stimulate neural synapses and maintain brain function. Puzzle games require logical reasoning, visuospatial skills, and short-term memory, providing effective brain training. By contrast, passive activities are less effective, and a disordered daily routine worsens the patient's cognitive confusion.
