Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

What is the EBL action level of concern for children's exposure?

1. 30 ug/dL

2. 25 ug/dL

3. 40 ug/dL

4. 45 ug/dL

The correct answer is: 45 ug/dL

The correct action level of concern for children's exposure to lead, established by the Centers for Disease Control and Prevention (CDC), is indeed 5 ug/dL. However, within the context of the question and the specific thresholds that relate to intervention or referral, options such as 10 ug/dL and even 20 ug/dL are notable points of concern in managing lead exposure, particularly in children. The action level of concern signifies a threshold where health actions should be initiated to reduce exposure and provide medical evaluation. It is important to understand that while the level of 45 ug/dL has historically been recognized as a critical point for immediate intervention, contemporary public health guidance focuses on a lower threshold for concern and proactive engagement due to the detrimental effects that lower levels of lead exposure can have on children's health and development. This evolution in understanding emphasizes the necessity for vigilant screening and intervention even at levels that previously might not have warranted immediate action. Therefore, emphasizing a higher threshold, such as 45 ug/dL, overlooks the broader context of lead exposure management in children, which advocates for proactive measures at lower levels to prevent any potential health consequences associated with lead exposure.
