Jane's partner, Billi, was diagnosed with schizophrenia. During an episode, Billi was hospitalized and treated with antipsychotic medications. Because Jane was worried about Billi's symptoms, Jane confronted the treating psychiatrist. "This is completely unacceptable," Jane said. "This medication makes Billi seem apathetic. She shuffles around without any facial expressions. The medication also makes Billi jerk and twitch for no apparent reason. She is more withdrawn and apathetic than I've ever seen her." Which of these medications was MOST likely being used to treat Billi?
? chlorpromazine (Thorazine)
? clozapine (Clozaril)
? risperidone (Risperdal)
? buspirone (Buspar)
