Q

What are characteristics of a Rancho Level 5?

A

confused, inappropriate, non-agitated
max assist
gross attention to environment, highly distractibly, requires continual redirection, difficulty learning new tasks, agitated by too much stimulation. may engage in social conversation, but with inappropriate verbalization

38
