護理師正在提供有關慢性疼痛管理的教育。下列何種非藥物策略最能改善慢性疼痛患者的睡眠品質？

核心概念：慢性疼痛常伴隨睡眠障礙，非藥物策略是重要的輔助治療。此題旨在評估護理師對改善慢性疼痛患者睡眠品質的非藥物介入措施的了解。 為何正確答案 D 對：放鬆技巧，如深呼吸（diaphragmatic breathing）或漸進式肌肉放鬆（progressive muscle relaxation），能啟動副交感神經系統，降低心率、血壓及皮質醇水平，有助於減輕疼痛感知、緩解焦慮和肌肉緊張，進而更容易入睡並維持睡眠。這類活動屬於「身心互動」（mind-body interventions），研究證實對改善慢性疼痛患者的睡眠品質有顯著成效。 為何其他選項錯： A. 睡前劇烈運動：可能使身體過度興奮，提高體溫和心率，反而干擾入睡。 C. 攝取咖啡因：咖啡因是中樞神經興奮劑，白天過量攝取會影響夜間睡眠，尤其對於睡眠本身就受影響的慢性疼痛患者，應避免。 D. 完全避免白天小睡：適度的白天小睡有助於恢復體力，但過長或太接近傍晚的小睡會影響夜間的睡眠驅力（sleep drive），對部分患者而言，部分睡眠的剝奪反而會增加夜間的睡眠效率。然而，單純「避免」並非最有效的策略，且對某些人可能適得其反，不如放鬆技巧直接改善睡眠生理狀態。 臨床思路/安全優先：在處理慢性疼痛的同時，必須整合生理與心理層面的照護。睡眠是身體修復和維持功能的重要環節，若睡眠品質不佳，將加劇疼痛感並影響生活品質。因此，提供患者易於實行的放鬆技巧，是提升其整體健康的優先考量。

Core concept: Chronic pain is often accompanied by sleep disturbances, and non-pharmacological strategies are an important adjunct to treatment. This item assesses the nurse's understanding of non-pharmacological interventions to improve sleep quality in clients with chronic pain. Why the correct answer (D) is right: Relaxation techniques such as diaphragmatic breathing or progressive muscle relaxation activate the parasympathetic nervous system, lowering heart rate, blood pressure, and cortisol levels. They help reduce pain perception, anxiety, and muscle tension, making it easier to fall asleep and stay asleep. These are mind-body interventions, and research supports their effectiveness in improving sleep quality among clients with chronic pain. Why the other options are wrong: A. Strenuous exercise before bed: may overstimulate the body, raise temperature and heart rate, and instead interfere with sleep onset. C. Caffeine intake: caffeine is a central nervous system stimulant, and excessive daytime intake can disrupt nighttime sleep, so clients with chronic pain (who already have sleep issues) should avoid it. D. Avoiding all daytime napping: brief daytime naps can help restore energy, but long or late-day naps can reduce nighttime sleep drive. For some clients, restricting naps may improve nighttime sleep efficiency. However, simply 'avoiding' is not the most effective strategy and may even be counterproductive for some, whereas relaxation techniques more directly improve sleep physiology. Clinical reasoning / Safety priorities: Management of chronic pain must integrate physical and psychological care. Sleep is critical for body repair and functioning; poor sleep worsens pain and reduces quality of life. Therefore, providing easy-to-implement relaxation techniques is a priority for improving overall health.
