The CDC advocates a multitier approach for environmental management of lead threats. This approach has which of the following steps?

The correct choice encompasses a comprehensive understanding of the multi-tiered approach advocated by the CDC for managing environmental threats from lead exposure. This approach integrates several critical steps that collectively address the complexities of lead hazard management.

The first step, the investigation and reduction of hazards, emphasizes the need to thoroughly identify where lead exposure is occurring and to systematically reduce those risks. This might involve assessing homes, schools, and other environments where lead might be present.

The second step, near universal screening, highlights the importance of early identification of lead exposure risks, particularly in vulnerable populations like children. By advocating for widespread screening, the CDC aims to ensure that those who are at risk are identified promptly and can receive appropriate interventions.

The third step, identification and remediation of hazards, points to the need for not only recognizing sources of lead exposure but also implementing effective strategies to remove or mitigate these hazards. This may involve physical remediation efforts, policy changes, and education for those at risk.

Thus, the integration of investigation, screening, identification, and remediation into a cohesive strategy represents a holistic approach for tackling the multifaceted issue of lead exposure, emphasizing the necessity of addressing all these components together to effectively protect public health.
