護理師教導社區團體預防鉛中毒。對幼兒家長哪項建議最重要？
A nurse is teaching a community group about preventing lead poisoning. Which advice is most important for parents of young children?
- AAllow children to play with old painted furniture允許兒童玩弄塗有舊油漆的家具
- BWash children's hands frequently✓ 正解經常清洗兒童的手
- CDo not test the home for lead不要對住宅進行鉛檢測
- DEncourage consumption of high-fat foods鼓勵攝取高脂肪食物
鉛中毒（Lead poisoning）對幼兒神經系統發育有不可逆的損害，主要透過手口接觸（Hand-to-mouth activity）攝入環境中的含鉛粉塵。預防的核心在於阻斷攝入途徑，頻繁洗手能有效清除手部殘留的鉛塵。此外，良好的營養狀態（特別是鈣、鐵充足）可競爭性抑制鉛的吸收，因此教育家長環境衛生與飲食指導是護理教學的優先重點。
Lead poisoning produces irreversible damage to the developing neurologic system of young children, primarily via hand-to-mouth ingestion of lead-containing dust in the environment. The cornerstone of prevention is interrupting the route of ingestion; frequent handwashing effectively removes residual lead dust from the hands. In addition, good nutritional status (particularly adequate calcium and iron) competitively inhibits lead absorption, so educating parents on environmental hygiene and dietary guidance is the priority focus of nursing teaching.
在美國，針對1978年前興建的房屋有嚴格的鉛危害告知（Lead-based paint disclosure）法律義務，護理師在社區衛教時亦會特別強調此歷史背景，這與台灣目前較少將房屋建築年代作為鉛中毒衛教重點略有不同。
