Final answer:
A child with autism spectrum disorder typically demonstrates repetitive behaviors and impaired social interactions, which are characteristic symptoms of ASD.
Step-by-step explanation:
A nurse assessing a child with autism spectrum disorder (ASD) should expect to see manifestations including repetitive behaviors and difficulty with social interactions. A characteristic symptom of ASD is impaired social skills, where individuals may have difficulty making and maintaining eye contact, understanding social cues, and feeling empathy for others. Additionally, they may engage in repetitive motor behaviors like rocking back and forth, show preoccupation with specific subjects, adhere to strict rituals, and display unusual language use. It is important to note that because ASD is a spectrum disorder, symptoms can vary greatly from person to person.
