The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to contracting lead poisoning?

Choice A reason: While living in older housing projects can pose a risk, the age of the child and their behaviors, such as hand-to-mouth activities, make younger children more susceptible. Choice B reason: A 2-year-old is at the highest risk due to their developmental stage, which includes frequent hand-to-mouth activity and the likelihood of playing in soil or dust that may be contaminated with lead. Choice C reason: Adolescents working in a paint factory may be exposed to lead; however, they are less likely to engage in hand-to-mouth behaviors that lead to ingestion, which is the primary route of lead poisoning in children. Choice D reason: A 10-year-old with Type 1 diabetes mellitus does not have an increased risk of lead poisoning based on their condition alone.
