What strategies can prevent lead poisoning in children?

The correct choice emphasizes a multi-faceted approach to preventing lead poisoning in children. Regular blood testing is essential because it helps in the early identification of elevated blood lead levels, allowing for prompt intervention. Education about lead sources is crucial, as it informs families about potential risks and how to mitigate them, such as recognizing lead paint hazards or avoiding contaminated soil. Home inspections are equally important, as they can identify lead hazards within the home environment, particularly in older buildings where lead-based paint might be present.

This comprehensive strategy not only addresses the immediate risks associated with lead exposure but also promotes awareness and preventive actions within the community. In contrast, other options may provide some benefits but do not comprehensively tackle the issue of lead poisoning. For instance, installing air filters might improve air quality but does not directly eliminate lead exposure sources, while providing iron supplements or limiting outdoor playtime may address certain health aspects but do not effectively prevent lead poisoning on their own.
