You are working on an inpatient psychiatric unit and are do an initial assessment on R.B., who has just been admitted. He has a diagnosis of schizophrenia, paranoid type. He is 22 years old and has been attending the local university and living at home with his parents. He has always been a good student and has been active socially. Last semester, his grades began declining, and he became very withdrawn. He spends most of his time alone in his room. His grooming has deteriorated; he can go days without bathing. For several weeks before admission, he insisted on keeping all of the blinds and curtains in the house closed. For the past 2 days, he has refused to eat, saying, "They have contaminated the food." As you approach R.B., you note that he appears to be carrying on a conversation with someone, but there is no one there. When you talk to him, he looks around and answers in a whisper but gives you little information. He states, "They are watching me and told me not to cooperate."
