He avoids contact with others and has complained to the supervising staff that he thinks people are reading his mind. Three days ago, he unplugged every electrical appliance on his floor of the shelter because he believed they were being used to transmit messages about him to others. The patient has schizophrenia and has been prescribed risperidone but has been unable to comply with his medications because of his unstable living situation. He is disheveled and malodorous. His thought process is disorganized and he does not make eye contact. Which of the following is the most appropriate long-term pharmacotherapy?? A: Intravenous propranolol, B: Oral haloperidol, C: Intramuscular benztropine, D: Oral diazepam, E: Intramuscular risperidone,  <response>: This is a question about choosing appropriate long-term pharmacotherapy for a 27-year-old man with schizophrenia who is exhibiting symptoms such as paranoia, disorganized thinking, and social withdrawal. The key points in the question stem are that the patient has a diagnosis of schizophrenia, has been prescribed risperidone previously but has been unable to take it regularly, and is currently exhibiting positive symptoms like delusions and disorganized thinking as well as negative symptoms like social withdrawal. The choices given include intravenous propranolol a beta blocker, oral haloperidol a typical antipsychotic, intramuscular benztropine an anticholinergic, oral diazepam a benzodiazepine, and intramuscular risperidone an atypical antipsychotic. For long-term management of schizophrenia, an atypical antipsychotic like risperidone would be most appropriate. Haloperidol is a reasonable option but has more extrapyramidal side effects. The other options would not treat the core symptoms of schizophrenia effectively.E: Intramuscular risperidone
