Katie Peterson, an 18-year-old female, has been referred to you by her primary care provider for recommendations and treatment for autism spectrum disorder (ASD). Throughout childhood and adolescence, Katie’s support has not been consistent in managing her ASD, and her parents are seeking a PMHNP to address Katie’s anxiety, frequent temper outbursts, and increasing difficulties interacting with her peers throughout the day.

Her medical history includes seizures since the age of 11 months. A baseline SPECT scan revealed overactivity in the basal ganglia and marked increased patchy uptake throughout her cerebral cortex.

You start the interview with her dad present.
During her psychiatric interview, you observe Katie with repetitive behaviors and poor eye contact. At one point, she turns the lights on and off repetitively for several minutes before she can sit down to complete her evaluation.
