A nurse is reviewing laboratory results of a client who has schizophrenia and is taking risperidone. For which of the following findings should the nurse notify the provider?

Choice A reason: A WBC count of 6,000/mm³ is within normal range (5,000-10,000), not indicating issues like agranulocytosis, a rare risperidone risk. It’s expected in schizophrenia treatment unless infection or drug effects alter it. This doesn’t warrant notification, as it’s unremarkable. Choice B reason: Blood glucose at 256 mg/dL exceeds normal (74-106), signaling hyperglycemia, a risperidone side effect linked to metabolic syndrome. In schizophrenia, this risks diabetes, requiring urgent provider action—diet, meds, or monitoring. This abnormality demands reporting, making it correct. Choice C reason: Sodium at 140 mEq/L is normal (136-145), not suggesting hyponatremia or other imbalances from risperidone. It’s a stable finding in schizophrenia care, needing no intervention. This routine result doesn’t require provider notification here. Choice D reason: Platelets at 250,000/mm³ are normal (150,000-400,000), not indicating thrombocytopenia or clotting issues with risperidone. It’s a safe level in schizophrenia treatment, requiring no action. This finding is benign, so it doesn’t need reporting.
