A nurse is reviewing the medical record of a client who has schizophrenia and is receiving olanzapine. Which of the following findings should the nurse identify as an adverse effect of olanzapine?

Choice A reason: A heart rate of 60/min is within normal limits for adults and is not considered an adverse effect of olanzapine. Choice B reason: Delusions of grandeur are a symptom of schizophrenia itself, not an adverse effect of olanzapine. Antipsychotics are prescribed to reduce such symptoms. Choice C reason: Oral candidiasis is not a typical adverse effect of olanzapine. It is more commonly associated with inhaled corticosteroid use. Choice D reason: Weight gain is a well-documented adverse effect of olanzapine due to its metabolic side effects, including increased appetite and changes in glucose and lipid metabolism. A gain of 3 lb in 2 weeks is clinically significant and should be monitored closely.
