A nurse is providing teaching to a client who has diabetes mellitus about the glycosylated hemoglobin blood test. Which of the following statements by the client indicates an understanding of this test?

A) Using the results of the glycosylated hemoglobin (HbA1c) test daily to modify insulin dosage is not accurate. The HbA1c reflects average blood glucose levels over the past 2-3 months and is not intended for immediate adjustments to insulin therapy. B) Drinking a glucose solution is not necessary for the HbA1c test. This test measures the percentage of hemoglobin that is glycated and does not require any specific preparation like glucose ingestion. C) Using this test to monitor how well blood glucose levels are controlled is accurate. The HbA1c test provides a long-term view of blood glucose control, helping both the client and healthcare provider assess the effectiveness of diabetes management strategies over time. D) Fasting is not required prior to the HbA1c test. Unlike other glucose tests, the HbA1c can be performed at any time without fasting, making it a convenient option for ongoing monitoring.
