A nurse is assisting with a developmental screening on a 4-year-old child.
Which of the following cognitive skills should the nurse expect the child to perform?
Classify objects by size, shape, and color
Understand the concept of conservation of matter
Use abstract reasoning to solve problems
Count backward from 10 to 1
The Correct Answer is A
Classify objects by size, shape, and color. A 4-year-old child should be able to recognize and name a few colors, starting with primary colors of red, yellow and blue. He should also be able to sort objects according to various characteristics, such as color, shape and size.
Choice B is wrong because the concept of conservation of matter is not understood by 4-year-olds.
This is the ability to recognize that the quantity of a substance remains the same even if its shape or appearance changes.
For example, a 4-year-old might think that a ball of clay has more clay than a flattened piece of clay. This concept is usually developed around 7 to 8 years of age.
Choice C is wrong because abstract reasoning is not a cognitive skill that 4-year-olds can perform.
Abstract reasoning is the ability to think beyond the concrete and literal, and use symbols, logic, and imagination to solve problems.
For example, a 4-year-old might not understand what a metaphor or a joke means.
This skill is usually developed around 11 to 12 years of age.
