A nurse is reviewing abnormal laboratory values for four clients who have schizophrenia and take clozapine.
For which of the following clients should the nurse withhold the medication and notify the provider immediately to have clozapine therapy discontinued?
A client who has a BUN of 22 mg/dL.
A client who has a serum potassium of 3.3 mEq/L.
A client who has a hematocrit of 55%.
A client who has a WBC of 2,900 cells/mm².
The Correct Answer is D
Choice A rationale:
A BUN of 22 mg/dL is slightly elevated but not a contraindication for clozapine.
Choice B rationale:
A serum potassium of 3.3 mEq/L is slightly low but not a contraindication for clozapine.
Choice C rationale:
A hematocrit of 55% is high but not a contraindication for clozapine.
Choice D rationale:
A WBC of 2,900 cells/mm² is low and can indicate agranulocytosis, a potentially life-threatening condition. Clozapine should be discontinued.
