Which child is most susceptible to lead poisoning during intake interviews?

• A. A 2-year-old who plays on aging outdoor playground equipment.
• B. A 4-year-old who rarely puts objects in the mouth.
• C. A 6-year-old who uses a digital device continuously.
• D. A 8-year-old who attends a private school in a modern building.

Answer: (A)

Lead exposure risk is highest in young children because their nervous systems are still developing and they frequently explore the world by putting objects in their mouths. In intake interviews, it’s important to identify environmental sources that could expose a child to lead, such as older paints and surfaces in contact with children. The child most susceptible here is the 2-year-old who plays on aging outdoor playground equipment, because old paint on that equipment can contain lead and toddlers are prone to mouthing objects and dust from the ground, increasing ingestion chances. The other scenarios involve factors that reduce risk—rare mouthing lowers intake, continuous digital device use isn’t related to lead exposure, and a modern building in a private school suggests fewer lead sources.
