A nurse is providing education to a client who is reviewing a consent form for a surgical procedure. Which of the following statements by the client indicates an understanding of the consent?

Choice A reason: A WBC count of 1,300/mm³ indicates severe leukopenia, a contraindication for clozapine due to its risk of agranulocytosis. Low white cells increase infection risk, requiring immediate discontinuation or monitoring per FDA guidelines, making this the critical finding to identify.
Choice B reason: Hemoglobin of 16 g/dL is within normal range (14-18 g/dL) and does not contraindicate clozapine use. Normal hemoglobin supports adequate oxygen transport, so this finding is unremarkable and incorrect for identifying a contraindication.
Choice C reason: Fasting blood glucose of 124 mg/dL indicates mild elevation but is not a contraindication for clozapine, which may worsen glucose control. Monitoring is needed, but this level does not preclude use, making it incorrect.
Choice D reason: Platelet count of 200,000/mm³ is normal (150,000-450,000/mm³) and does not contraindicate clozapine. Normal platelets ensure proper clotting, so this finding is not a concern for clozapine administration, making it incorrect.

Choice A reason: Hypernatremia is unlikely with 0.45% sodium chloride, a hypotonic solution that dilutes serum sodium. Over-infusion risks hyponatremia, not high sodium levels. Monitoring for hypernatremia is inappropriate, as the solution’s low sodium content does not contribute to elevated sodium in fluid therapy.
Choice B reason: Assessing for fluid overload is essential, as 0.45% sodium chloride, being hypotonic, can cause water to shift into cells, risking pulmonary or cerebral edema. This is critical in clients with renal or cardiac issues, where monitoring for dyspnea or swelling ensures safe fluid administration.
Choice C reason: Hypoglycemia is not directly linked to 0.45% sodium chloride, which affects fluid and electrolytes, not glucose. Fluid shifts may indirectly stress metabolism, but hypoglycemia relates to fasting or insulin issues, making this an inappropriate focus for monitoring in this fluid therapy context.
Choice D reason: Dehydration is unlikely, as 0.45% sodium chloride provides free water, promoting hydration. It corrects hypernatremia or replaces fluid losses. Evaluating for dehydration is unnecessary unless infusion is inadequate or losses persist, which is not indicated in the context of this hypotonic solution.
