A diabetic patient is taking regular and NPH insulin to manage his diabetes. What is the best evaluation tool to measure the overall patient response to the insulin therapy?
A) Blood pressure
B) Bilirubin level
C) Glycosylated hemoglobin (HbAlc) levels
D) Fasting blood glucose levels
C
Feedback:
HbAlc levels provide a 3-month average of glucose levels, which provides the best evaluation tool to measure the overall patient response to the treatment plan. Blood pressure readings would be used to evaluate a patient's response to an antihypertensive drug. Bilirubin could indicate liver function. Fasting blood glucose levels provide only a baseline blood sugar and no historical overview. Comparing fasting blood glucose levels with HbAlc is like comparing a picture to a video because the HbAlc looks back across a period of 3 months whereas a blood glucose test result only tells you about the exact moment the blood was drawn.
