A 2-year-old with lead exposure at 14 mcg/dL—what is the appropriate public health action?

• A. A long bone x-ray film
• B. A low-calcium diet
• C. Referral to the health department for environmental investigation
• D. A high-calcium diet

Answer: (C)

Lead exposure in a toddler signals an environmental hazard that must be addressed to prevent ongoing harm. The best public health action is to involve the local health department to conduct an environmental investigation. Public health agencies have the authority and resources to identify lead sources in the home or surroundings—such as deteriorating lead-based paint, contaminated dust, soil, or water—and coordinate remediation, education, and follow-up testing to ensure the child’s environment is safe. This approach directly targets the exposure source and protects future development. Imaging of the bones isn’t the standard step for managing lead exposure and won’t address the source of exposure. Simply adjusting calcium intake doesn’t remove lead from the environment, and while nutrition can support overall health, it is not the primary public health intervention in this scenario.
