A nurse is providing anticipatory guidance about child development to the parents of a preschooler. Which of the following developmental tasks should the nurse include as being expected of a preschooler?

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.

It is important to recognize that picky eating is a common behavior among preschool-age children and may be a normal part of their development. Children at this age often exhibit preferences for certain foods and may be resistant to trying new foods or eating a wide variety of foods. It is important for parents to understand that this behavior is generally temporary and will likely improve over time.

The nurse should reassure the mother that it is normal for young children to have fluctuations in their appetite and food preferences. Encouraging a positive mealtime environment and offering a variety of healthy foods is important, but pressuring or forcing the child to eat can lead to negative associations with food and mealtime.

Emphasizing the quantity of food consumed over the quality is not recommended, as it may promote unhealthy eating habits. It is important to prioritize offering a balanced diet with a variety of nutrient-rich foods.

Adding fruit juice to the child's diet to increase vitamin intake is not recommended as the primary strategy. Fruit juice is often high in sugar and low in fiber, and excessive consumption can contribute to poor eating habits and dental caries. It is better to focus on offering whole fruits and vegetables for their nutritional benefits.

Having the child remain at the table after meals to increase food intake is not recommended either. It is important to respect the child's appetite and avoid creating negative associations with mealtime. Forcing a child to stay at the table can increase mealtime stress and may further reinforce picky eating behaviors.

Overall, the nurse should provide reassurance to the mother, promote a positive mealtime environment, offer a variety of healthy foods, and allow the child to regulate their own food intake.
