Which laboratory test is commonly used to monitor long-term glycemic control in individuals with diabetes mellitus by measuring average blood glucose levels over the past 2 to 3 months?
Fasting blood glucose test.
Oral glucose tolerance test (OGTT).
Hemoglobin A1c (HbA1c) test.
C-peptide test.
The Correct Answer is C
The Hemoglobin A1c (HbA1c) test measures the percentage of hemoglobin that is glycated, reflecting average blood glucose levels over the past 2 to 3 months. It is a valuable tool for assessing long-term glycemic control.
Incorrect choices:
a. This choice is incorrect. The fasting blood glucose test measures blood glucose levels after an overnight fast and provides a snapshot of current glucose levels, rather than long-term control.
b. This choice is incorrect. The oral glucose tolerance test (OGTT) measures how the body responds to a glucose load and is used to diagnose diabetes and impaired glucose tolerance, rather than monitor long-term control.
d. This choice is incorrect. The C-peptide test is used to assess insulin production by measuring the level of C-peptide, a byproduct of insulin production.

Basal-bolus insulin therapy involves administering a continuous basal insulin infusion to provide background insulin coverage and delivering bolus doses of insulin before meals to cover postprandial glucose elevations.
Incorrect choices:
a. This choice is incorrect. Oral antidiabetic medications are not used in basal-bolus insulin therapy.
c. This choice is incorrect. Sliding-scale insulin therapy involves adjusting insulin doses based on current blood glucose levels, rather than providing consistent basal and mealtime coverage.
d. This choice is incorrect. Insulin glargine therapy provides long-acting basal insulin coverage but does not involve bolus doses before meals.
