護理師向家長衛教鉛中毒預防。哪些建議是必須的？（選所有適合的）
A nurse is teaching parents about lead poisoning prevention. Which recommendations are essential? (Select all that apply.)
- AWash children's hands before eating✓ 正解進食前清洗兒童雙手
- BProvide a diet high in calcium and iron✓ 正解提供高鈣和高鐵飲食
- CUse hot tap water for mixing infant formula使用熱自來水沖調嬰兒配方奶
- DRegularly clean floors and surfaces with wet mopping✓ 正解定期以濕拖把清潔地板和表面
- EAvoid sandboxes as they can harbor lead避免使用沙坑，因為可能藏有鉛
鉛中毒預防的重點在於減少攝入途徑與提升身體防禦。兒童常透過手口接觸攝入環境中的含鉛灰塵，因此洗手至關重要。充足的鈣與鐵攝取能競爭性地抑制腸道對鉛的吸收，從而降低鉛毒性。濕式清潔（Wet mopping）能避免灰塵飛揚，有效清除含鉛粉塵。熱水器流出的熱水易溶出管路中的鉛，絕對不可用於沖泡奶粉。沙箱並非主要污染源，重點應放在居家環境的清潔。
Lead poisoning prevention focuses on reducing routes of ingestion and strengthening the body's defenses. Children frequently ingest environmental lead dust via hand-to-mouth contact, so hand washing is essential. Adequate calcium and iron intake competitively inhibit intestinal absorption of lead and lower toxicity. Wet mopping prevents dust from becoming airborne and effectively removes lead-containing particles. Hot tap water can leach lead from plumbing and must not be used to prepare infant formula. Sandboxes are not a major source of lead contamination, and the emphasis should remain on cleaning the home environment.
