A nurse is obtaining a history from a client who has been taking olanzapine to treat schizophrenia. Which of the following questions should the nurse ask the client?

Choice A reason: Olanzapine, an antipsychotic, can cause metabolic side effects like hyperglycemia, leading to increased thirst, a diabetes symptom. In schizophrenia treatment, monitoring this is key due to long-term risk. This question targets a common, serious effect, making it the priority to ask. Choice B reason: Unintentional weight loss isn’t typical with olanzapine, which often causes weight gain via appetite increase. Schizophrenia itself rarely causes this unless appetite drops. This question misses the drug’s profile, so it’s not the best to assess side effects. Choice C reason: Ringing in the ears (tinnitus) isn’t a known olanzapine side effect; it’s linked to drugs like quinine, not antipsychotics. It’s irrelevant to schizophrenia treatment monitoring. This question lacks clinical basis for this medication, making it incorrect. Choice D reason: Decreased taste isn’t a reported olanzapine effect; it may alter appetite, but not taste perception directly. Schizophrenia might affect senses indirectly, but this isn’t drug-related. This question doesn’t target a key side effect, so it’s not the priority.
