A health care provider considers which antipsychotic medication to prescribe for a patient diagnosed with schizophrenia who has auditory hallucinations and poor social functioning. The patient is also overweight and has hypertension. Which drug should the nurse advocate?

A) Clozapine (Clozaril)
B) Ziprasidone (Geodon)
C) Olanzapine (Zyprexa)
D) Aripiprazole (Abilify)

Aripiprazole is an atypical antipsychotic medication that is effective against both positive and negative symptoms of schizophrenia. It causes little or no weight gain and no increase in glucose, high- or low-density lipoprotein cholesterol levels, or triglycerides, making it a reasonable choice for a patient with obesity or heart disease. Clozapine may produce agranulocytosis, making it a poor choice as a first-line agent. Ziprasidone may prolong the QT interval, making it a poor choice for a patient with cardiac disease. Olanzapine fosters weight gain.
