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

Which of the following is a health effect of lead poisoning in children?

1. Loss of appetite

2. Brain damage

3. Coughing fits

4. Frequent headaches

The correct answer is: Brain damage

The health effect of lead poisoning in children that is most well-documented and severe is brain damage. Lead exposure can disrupt the development of a child's brain and nervous system, leading to long-term cognitive deficits, developmental delays, and behavioral issues. Even low levels of lead in the blood can be harmful, affecting a child's attention span, academic performance, and overall intelligence. While loss of appetite may occur in some cases of lead poisoning, it is not as significant or direct an effect as brain damage. Coughing fits and frequent headaches are also not typical indicators of lead exposure in children; they may stem from other health issues unrelated to lead exposure. Thus, the most critical and alarming consequence of lead poisoning is its potential to cause irreversible brain damage, which can have lifelong effects on a child's health and development.
