A nurse is providing teaching about home care to the parents of a child who has autism spectrum disorder. Which of the following instructions should the nurse include?

A. Incorrect. Maintaining a flexible daily schedule for the child may increase their anxiety and confusion, as they may have difficulty adapting to changes in routine and expectations. The nurse should advise the parents to establish a consistent and structured schedule for the child, with clear rules and boundaries. B. Correct. Using a reward system to modify the child's behavior is an effective strategy to reinforce positive behaviors and reduce negative ones. The nurse should help the parents identify specific and measurable goals for the child, and provide them with praise, tokens, or privileges when they achieve them. C. Incorrect. Providing a variety of family members to care for the child may overwhelm them and impair their social skills development, as they may have difficulty forming attachments and communicating with different people. The nurse should encourage the parents to select one or two primary caregivers for the child, who can provide them with consistent and supportive interactions. D. Incorrect. Administering alprazolam as needed to reduce the child's anxiety is not recommended, as it may cause adverse effects such as sedation, dependence, or withdrawal symptoms. The nurse should educate the parents about nonpharmacological interventions for anxiety, such as relaxation techniques, cognitive behavioral therapy, or social skills training.
