CDPH Lead Inspector/Assessor California State Practice Exam

Which of the following is commonly associated with lead exposure?

1. Memory enhancement

2. Hyperactivity

3. Lower than average intelligence

4. Physical agility

The correct answer is: Hyperactivity

B is the correct choice because hyperactivity is a well-documented behavioral issue often linked to lead exposure, particularly in children. Lead poisoning can cause a range of neurological impairments that affect cognitive functioning and behavior. Studies have shown that children with elevated blood lead levels may exhibit increased levels of hyperactivity and impulsivity, which can impact their ability to concentrate and perform in academic settings. Lead exposure can interfere with the development of the central nervous system, particularly in young children whose brains are still developing. This can manifest in various behavioral issues, including hyperactivity. Consequently, identifying and mitigating lead exposure is critical for preventing these adverse developmental outcomes. While lower than average intelligence is also associated with lead exposure, it is more nuanced and encompasses broader cognitive impairments, rather than being a direct behavior like hyperactivity. Memory enhancement and physical agility, on the other hand, are generally not linked to lead exposure and may suggest improved performance rather than the negative consequences associated with lead toxicity.
