The lab results for an older patient indicate a glycosylated hemoglobin (HbA1c) result of 6.5%. What is the nurse's best response to the patient?
1. "Your blood sugar levels have been within normal limits for the past three months."
2. "Your HbA1c level indicates a pattern of low blood glucose levels."
3. "Your HbA1c indicates that you are anemic and will require a blood transfusion."
4. "Your average blood glucose level averaged 126 mg/dl over the past 3 months, which is high."
4. "Your average blood glucose level averaged 126 mg/dl over the past 3 months, which is high."
Explanation: 1. An HbA1c of 6.5% is high and is not within normal limits.
2. Glycosylated hemoglobin of 6.5% indicates a pattern of high blood glucose, not low.
3. Glycosylated hemoglobin is not used to diagnose anemia.
4. Glycosylated hemoglobin estimates a patient's blood glucose over the past 3 months by measuring how much glucose is attached to the hemoglobin in red blood cells, which have an average life span of about 4 months. An HbA1c of 6.5 relates to an average glucose level of 126 mg/dl. A normal glycosylated hemoglobin result is 5.0%.
