A nurse is reviewing the medical record of a male client who has schizophrenia and is taking clozapine. Which of the following findings should the nurse identify as a contraindication to the administration of clozapine?
Fasting blood glucose 124 mg/dL (70 to 110 mg/dL)
Absolute neutrophil count 1,300/mm3 (2,500 to 8,000/mm3)
Heart rate 58/min
Hgb 12.5 g/dL (14 to 18 g/dL)
The Correct Answer is B
A. Elevated fasting blood glucose is a concern but does not immediately contraindicate clozapine administration. It can be monitored and managed.
B. Clozapine can cause agranulocytosis, and a low absolute neutrophil count (ANC) is a contraindication for the medication. The threshold for stopping clozapine is typically an ANC of less than 1,500/mm3.
C. A heart rate of 58/min is not a contraindication for clozapine. It may require monitoring but is not necessarily concerning.
D. An Hgb level of 12.5 g/dL is within the normal range and does not contraindicate the use of clozapine.
