Explanation
Lead is a toxic metal that can be found in old paint, dust, soil, and certain consumer products. Children are particularly vulnerable to lead poisoning, which can lead to developmental delays, learning difficulties, and other health problems.
Pesticides are chemicals used to control pests, such as insects and rodents. Children can be exposed to pesticides through contaminated food, water, or direct contact with treated areas. Pesticide exposure has been linked to various health issues, including neurodevelopmental disorders and respiratory problems.
Certain medications can be toxic to children, especially if taken in excessive amounts or without appropriate supervision. Accidental ingestion of medications, including over-the-counter and prescription drugs, is a significant concern in pediatric care.
While air pollution is a significant environmental factor that can impact children's health, it is not typically considered one of the most common toxins in pediatric care.
Correct Answer is D
Explanation
At this age, children have developed the physical coordination and balance necessary to navigate stairs with more control and safety. They may still require support from holding onto the railing for added stability and security. As children grow older, they continue to refine their motor skills, balance, and coordination, and by the age of 4, 5, and 6 years, they typically demonstrate more advanced stair-descending skills, such as alternating feet and using the railing less for support.
