A nurse is planning care for a preschooler who has autism spectrum disorder. Which of the following interventions should the nurse include in the plan?

The correct answer is D: Establish a reward system. This intervention is appropriate for a preschooler with autism spectrum disorder as it helps reinforce positive behaviors and encourages desired actions. By using a reward system, the nurse can motivate the child to engage in specific activities or tasks. Holding the child during assessments (A) may not be appropriate as it can cause sensory overload. Maintaining extended eye contact (B) may be overwhelming for a child with autism. Engaging in cooperative play (C) may be challenging for a child with autism who may struggle with social interactions.
