護理師正在評估一位因焦慮而失眠的病人，何項建議最為恰當？
A nurse is assessing a client who is experiencing insomnia related to anxiety. Which recommendation is most appropriate?
- AEstablish a regular sleep-wake cycle.✓ 正解建立規律的睡眠-覺醒週期
- BTake long naps during the day.白天進行長時間午睡
- CDrink a cup of coffee before bedtime.睡前喝一杯咖啡
- DEngage in stimulating activities before sleep.睡前從事刺激性活動
睡眠衛生（Sleep hygiene）是改善焦慮相關失眠的核心策略。規律的睡眠-清醒週期能穩定生理時鐘（Circadian rhythm），提升睡眠品質。其他選項均會干擾睡眠機制：咖啡因是興奮劑，日間睡眠會減少夜間驅動力（Sleep drive），而刺激性活動則會增加交感神經活性。護理重點在於行為調整，幫助病患建立良好的睡眠環境與習慣。
Sleep hygiene is the core strategy for improving anxiety-related insomnia. A regular sleep-wake cycle can stabilize the circadian rhythm and enhance sleep quality. The other options all disrupt sleep mechanisms: caffeine is a stimulant, daytime sleep reduces nocturnal sleep drive, and stimulating activities increase sympathetic nervous system activity. The nursing focus is on behavioral adjustment, helping the patient establish a good sleep environment and habits.
