At what Piaget stage are children developmentally ready to learn how to draw up insulin?

The correct answer is the stage of concrete operations, which occurs approximately between the ages of 7 and 11 years. During this phase, children begin to think logically about concrete events. They gain a better understanding of the concept of conservation, and they can classify objects and understand the order of operations, which is critical in tasks that require following specific steps, such as drawing up insulin.

At this stage, children are able to handle tasks that involve logical reasoning but still struggle with abstract ideas. This makes them ready to learn practical skills that require a clear sequence of operations and an understanding of cause and effect. Learning to draw up insulin involves not only following a specific technique but also measuring and understanding dosages, which is more aligned with their cognitive abilities in the concrete operational stage.

In contrast, the other stages—pre-operational and sensorimotor—are earlier stages focused on basic sensory experiences and symbolic thought, where children do not yet have the ability to manage the kind of logical thinking and sequential skills needed for such a task. The formal operations stage, which begins around age 12, introduces abstract reasoning, but children in the concrete operations stage are more adequately prepared for practical tasks within their current cognitive development.
