Which blood laboratory test result indicates to the nurse that the patient is maintaining overall good control of his or her diabetes?
a. Hemoglobin A1c is 5.2%.
b. Ketone levels are negative.
c. Fasting blood glucose level is 88 mg/dL.
d. Glucose level immediately following a meal is 150%.
A
Hemoglobin A1c levels reflect the amount of fluctuation of blood glucose levels for at least the last 60 days. The closer this number is to normal, the fewer episodes of hyperglycemia the patient will have experienced. Although a fasting blood glucose level of 88% and a negative blood ketone level are good, they only reflect the control a patient has experienced for the past 24 hours. Glucose levels immediately after a meal are the least accurate way to measure glucose control.
