Past medical history is significant for chronic schizophrenia, managed with an antipsychotic medication. The patient has a low-grade fever and is slightly tachycardic. Physical examination is significant for the presence of tonsillar exudates. A CBC shows a markedly decreased WBC count. The patients antipsychotic medication is immediately discontinued. Which of the following is the antipsychotic medication that could have caused this problem?? A: Quetiapine, B: Olanzapine, C: Risperidone, D: Clozapine, E: Haloperidol,  <response>: This is a clinical vignette about a 37-year-old woman with fever, tachycardia, tonsillar exudates, and leukopenia. She has a history of schizophrenia managed with an antipsychotic medication. The key finding is the low white blood cell WBC count, which indicates leukopenia.

The other antipsychotics listed are not typically associated with this side effect. Therefore, the patients antipsychotic medication that likely caused the leukopenia is clozapine.D: Clozapine
