關於鉛中毒預防，下列哪項陳述是正確的？
Which of the following statements about lead poisoning prevention is correct?
- AChildren should have their blood lead levels tested✓ 正解兒童應接受血鉛濃度檢測
- BVacuuming effectively removes all lead dust吸塵能有效清除所有鉛粉塵
- CLead poisoning is only caused by lead-based paint鉛中毒僅由含鉛油漆引起
- DLead levels are safe in small amounts少量鉛濃度是安全的
鉛中毒（Lead poisoning）對兒童的神經系統發育有不可逆的損害。核心概念在於鉛無安全暴露量（no safe level of lead exposure），因此預防與早期篩檢至關重要。血中鉛濃度檢測（Blood lead level screening）是唯一能早期發現並介入的臨床手段。護理師需教育家長鉛的來源不僅限於舊屋油漆，還包括土壤、自來水管線、傳統藥物及進口玩具等，並強調正確的清潔方式以避免揚塵。
Lead poisoning causes irreversible damage to the developing nervous system of children. The central concept is that there is no safe level of lead exposure, making prevention and early screening crucial. Blood lead level screening is the only clinical means of detecting exposure early and intervening. The nurse should teach parents that sources of lead extend beyond old paint to include soil, water supply piping, traditional medicines, and imported toys, and should emphasize proper cleaning techniques to avoid resuspending lead dust.
美國對鉛暴露的篩檢有嚴格的聯邦指引（CDC guidelines），針對高風險區域（如老舊建築密集區）有強制性篩檢政策。台灣則較少針對全體兒童進行例行性血鉛篩檢，多針對職業暴露或特定高風險個案。
