A toddler was recently diagnosed with autism spectrum disorder (ASD). The nurses teaches the family about the disorder. Which of the following behaviors does the nurse teach the family to expect as manifestations of ASD?

Rationale: A. Somatic problems including frequent stomachaches and headaches: While some children with ASD may have gastrointestinal complaints or somatic symptoms, these are not core manifestations of the disorder. These issues may be secondary to stress, anxiety, or sensory sensitivities rather than defining features. B. Destructiveness such as intentionally breaking toys, furniture, etc.: Intentional destructiveness is not a typical behavior associated with ASD. Children with ASD may have difficulty with frustration or transitions, but deliberately breaking objects is more characteristic of behavioral disorders rather than autism. C. Repetitive behavior such as counting, arranging toys in a line, or hand flapping: Repetitive and stereotyped behaviors are hallmark features of ASD. These actions reflect the child’s need for predictability, sensory stimulation, or self-regulation and are commonly observed during early childhood. D. Impulsive behavior such as throwing toys or running into the street without looking: Impulsivity is not a core symptom of ASD. While children with autism may have challenges with safety awareness or executive functioning, this behavior is more typical of attention-deficit/hyperactivity disorder (ADHD) than ASD.
