On the way to treat a student in the lunchroom, a COTA working under a fee-for-service contract observes another client with Level 1 autism spectrum disorder without intellectual impairment (Asperger syndrome) reacting negatively to a student who accidentally brushed against the client in line. Which response would be BEST?
1) Ignore the situation and continue treating the student
2) Immediately intervene and separate the client from the student
3) Talk to the client and explain that the student did not mean to brush against them
4) Report the incident to the supervisor and let them handle the situation
