A nurse is reviewing a client's laboratory results and sees that their hemoglobin A1C is 9%. Which of the following statements from the nurse is appropriate?

Rationale: A. "Your average blood sugar is high": Hemoglobin A1C reflects the average blood glucose levels over the past 2–3 months. A value of 9% indicates that the client’s overall blood sugar has been consistently above the recommended target, providing a clear explanation of long-term glycemic control. B. "Your blood sugar is too high after meals": While postprandial glucose contributes to overall A1C, the test reflects an average over time rather than isolated after-meal spikes. Focusing only on post-meal levels may misrepresent the broader picture of glycemic control. C. "Your blood sugar is very unstable": A1C indicates long-term average glucose rather than fluctuations or variability. Lab values alone cannot determine whether blood sugar is unstable or fluctuating dramatically throughout the day. D. "You have many dangerously low blood sugar levels": Hypoglycemia is not indicated by an elevated A1C. A 9% value reflects hyperglycemia over time, not frequent low blood sugar episodes.
