A nurse is reviewing the medical record of a 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?
Heart rate 58/min.
Fasting blood glucose 100 mg/dL.
WBC count 2,900/mm3.
Hgb 14 g/dL.
The Correct Answer is C
Choice A rationale:
Heart rate 58/min. Clozapine, an atypical antipsychotic medication, can cause bradycardia (slow heart rate) as a side effect. However, the heart rate of 58/min is within the normal range for adults, so it is not a contraindication for clozapine administration.
Choice B rationale:
Fasting blood glucose 100 mg/dL. A fasting blood glucose level of 100 mg/dL is within the normal range (70-99 mg/dL) for adults. It is not a contraindication for clozapine administration.
Choice C rationale:
WBC count 2,900/mm3. Clozapine can cause agranulocytosis, a severe reduction in white blood cell (WBC) count, which can lead to increased susceptibility to infections. A WBC count of 2,900/mm3 is significantly below the normal range (4,000-11,000/mm3) and is a contraindication for clozapine administration due to the risk of severe immunosuppression.
Choice D rationale:
Hgb 14 g/dL. Hemoglobin (Hgb) level of 14 g/dL is within the normal range for adult males (13.8-17.2 g/dL) and females (12.1-15.1 g/dL). It is not a contraindication for clozapine administration.

No explanation
Correct Answer is A
Explanation
Choice A rationale:
Potato pancakes made from potatoes do not contain gluten, making them suitable for someone with celiac disease. Gluten is a protein found in wheat, barley, and rye, so individuals with celiac disease must avoid foods containing these grains.
Choice B rationale:
Wheat crackers contain gluten and are not appropriate for someone with celiac disease. Avoiding gluten is crucial for individuals with this condition to prevent damage to the small intestine.
Choice C rationale:
White flour tortillas are typically made from wheat flour and contain gluten. Individuals with celiac disease should avoid products made from wheat flour to prevent adverse reactions.
Choice D rationale:
Canned barley soup contains barley, which is a gluten-containing grain. Individuals with celiac disease should avoid barley-based products as they contain gluten.
