A nurse is assisting with evaluating teaching with a client who reports insomnia. Which of the following client statements indicates an understanding of the teaching?

Choice A reason : Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. While the causes of ADHD are not fully understood, current research does not establish childhood obesity as a direct risk factor for developing ADHD. ADHD is thought to be linked to genetic factors and certain environmental exposures during pregnancy.

Choice B reason : Hypotension, or low blood pressure, is generally not associated with childhood obesity. In fact, obesity, especially in the long term, is more commonly linked to hypertension (high blood pressure) due to increased strain on the heart and blood vessels, and not hypotension.

Choice C reason : Rheumatoid arthritis is an autoimmune condition that causes joint inflammation and damage. It is not typically considered a direct complication of childhood obesity. While obesity can contribute to joint problems due to increased mechanical stress, it is not a known cause of autoimmune conditions like rheumatoid arthritis.

Choice D reason : Diabetes mellitus, particularly type 2 diabetes, is a well-documented potential complication of childhood obesity. Obesity increases the risk of developing insulin resistance, which can lead to elevated blood sugar levels and eventually type 2 diabetes. The excess fat, particularly visceral fat, is associated with chronic inflammation and metabolic changes that contribute to the development of diabetes⁴.

The correct answer is: d. Formal operational

Choice A: Concrete operational

During the concrete operational stage, which typically occurs between the ages of 7 and 11, children develop logical thinking skills. They begin to understand the concept of conservation, the idea that quantity remains the same despite changes in shape or appearance. However, their thinking is still very concrete and tied to tangible objects and real events. Abstract thinking is not yet developed at this stage.

Choice B: Sensorimotor

The sensorimotor stage spans from birth to about 2 years of age. In this stage, infants learn about the world through their senses and actions. They develop object permanence, the understanding that objects continue to exist even when they cannot be seen, heard, or touched. Abstract thinking does not occur in this stage as infants are focused on immediate sensory experiences and motor activities.

Choice C: Preoperational

The preoperational stage occurs between the ages of 2 and 7. During this stage, children begin to engage in symbolic play and learn to manipulate symbols, but they do not yet understand concrete logic. Their thinking is still egocentric, meaning they have difficulty seeing things from perspectives other than their own. Abstract thinking is not a characteristic of this stage.

Choice D: Formal operational

The formal operational stage begins around age 12 and continues into adulthood. This stage is characterized by the development of abstract thinking and hypothetical reasoning. Individuals in this stage can think about abstract concepts, consider possible outcomes and consequences of actions, and use systematic ways to solve problems. This stage marks the emergence of scientific reasoning and the ability to think about abstract ideas.
