護理師建議戶外工作者預防中暑，哪項建議正確？
Which action is correct for a nurse to take to prevent heat stroke in a client working outdoors?
- AWear dark-colored, heavy clothing穿著深色、厚重的衣物
- BTake frequent breaks in a cool, shaded area✓ 正解在陰涼處頻繁休息
- CSchedule intense work during the hottest part of the day安排在最炎熱的時段進行劇烈工作
- DDrink fluids only when thirsty只在口渴時補充水分
中暑（Heat stroke）是熱傷害中最嚴重的類型，特徵為體溫調節失常導致核心體溫超過 40°C（104°F）。預防中暑的核心在於「散熱」與「水分補充」。護理師在衛教時應強調主動預防，而非等到出現症狀才行動。在涼爽陰涼處定期休息（B）能有效中斷體溫持續攀升。臨床思路上，應識別出錯誤的觀念：例如口渴才喝水通常已代表脫水（D），或是穿著阻礙排汗的衣物（A）。有效的預防措施必須能促進熱量的傳導與對流散失。
Heat stroke is the most severe form of heat-related illness, characterized by failure of thermoregulation and a core body temperature exceeding 40°C (104°F). The core of prevention is heat dissipation and fluid replacement. The nurse should emphasize proactive prevention rather than waiting for symptoms to appear. Regularly resting in a cool, shaded area (B) effectively interrupts the continuing rise in body temperature. Clinical reasoning involves identifying incorrect beliefs: drinking only when thirsty usually means dehydration has already occurred (D), and wearing clothing that hinders sweating (A). Effective prevention must promote heat dissipation via conduction and convection.
美國 OSHA（職業安全與健康管理局）對戶外工作有嚴格的「水、陰涼、休息（Water. Rest. Shade.）」規定。NCLEX 題目常反映這些職業安全指引。
