Step-by-step explanation:
A nurse should identify impaired social skills, repetitive motor behaviors, and strict adherence to certain rituals as typical developmental characteristics of a client diagnosed with severe intellectual disability. These characteristics are often seen in individuals with autism spectrum disorder (ASD), which is associated with intellectual disability. Children with ASD may have difficulty making eye contact, reading social cues, and displaying empathy for others. They may also engage in repetitive motor behaviors and have a strong attachment to routines.
