Health Medical Homework Help

I need an explanation for this Nursing question to help me study.

C.Z. is a 20-year-old Caucasian male who is in his second year of college. He is seeking treatment due to persistent fears that campus security and the local police are tracking and surveilling him. He cites occasional lags in his internet speed as evidence that surveillance devices are interfering with his electronics. His intense anxiety about this has begun getting in the way of his ability to complete schoolwork, and his friends are concerned – he says they have told him, “you’re not making sense.”

C.Z. occasionally laughs abruptly and inappropriately and sometimes stops speaking mid-sentence, looking off in the distance as though he sees or hears something. He expresses concern about electronics in the room (phone, computer) potentially being monitored and asks repeatedly about patient confidentiality, stating that he wants to be sure the police won’t be informed about his treatment. His beliefs are fixed, and if they are challenged, his tone becomes hostile.
