The nurse notes that the HbA1c level of an assigned patient demonstrated a drop from 9.4% to 5.4%. What inference can best be made about this patient?

A. The patient is demonstrating improved control of hyperglycemia over the last several months: The HbA1c level reflects the average blood glucose level over the past 2-3 months. A drop from 9.4% to 5.4% indicates a significant improvement in blood sugar control. B. The patient has less need for insulin: A drop in HbA1c indicates improved blood sugar control, but it doesn't directly indicate that the patient has reduced insulin needs. Insulin requirements can still vary depending on the individual’s treatment plan and overall health. C. The patient is experiencing a reduction in insulin sensitivity: Improved control of hyperglycemia (as evidenced by the drop in HbA1c) suggests better insulin sensitivity, not a reduction. Insulin sensitivity typically improves with better glucose control. D. The patient has been less compliant with the prescribed treatment regimen: A lower HbA1c suggests better compliance with treatment; usually indicates successful management of blood glucose levels, which often results from adhering to the prescribed regimen.
