Which medication works by increasing insulin sensitivity in peripheral tissues, facilitating glucose uptake by cells, and is commonly used in the treatment of type 2 diabetes mellitus?
Metformin.
Glipizide.
Insulin lispro.
Exenatide.
The Correct Answer is A
Metformin is a commonly used oral antidiabetic medication that improves insulin sensitivity in peripheral tissues, reduces hepatic glucose production, and enhances glucose uptake by cells.
Incorrect choices:
b. This choice is incorrect. Glipizide is a sulfonylurea medication that stimulates insulin secretion from the pancreas, rather than increasing insulin sensitivity.
c. This choice is incorrect. Insulin lispro is a rapid-acting insulin analog used for mealtime coverage in insulin therapy.
d. This choice is incorrect. Exenatide is a glucagon-like peptide-1 (GLP-1) receptor agonist that stimulates insulin secretion and suppresses glucagon release, but it does not primarily target insulin sensitivity.

Explanation
Gestational diabetes mellitus (GDM) is a type of diabetes that develops during pregnancy and is characterized by high blood glucose levels. It usually resolves after childbirth but increases the risk of developing type 2 diabetes in the future.
Incorrect choices:
a. This choice is incorrect. GDM typically resolves after childbirth, not after.
b. This choice is incorrect. GDM is not a rare condition; it affects a significant percentage of pregnant women.
c. This choice is incorrect. Women with GDM have an increased risk of developing type 2 diabetes, not type 1 diabetes, later in life.
Correct Answer is D
Explanation
The OGTT measures the body's ability to clear glucose from the blood by drinking a glucose solution and measuring blood glucose levels at specific intervals. It is commonly used to diagnose diabetes mellitus.
Incorrect choices:
a. This choice is incorrect. The fasting blood glucose test measures blood glucose levels after an overnight fast and is not specifically used to assess glucose clearance.
b. This choice is incorrect. The HbA1c test measures average blood glucose levels over the past 2-3 months and is not specifically used to assess glucose clearance.
c. This choice is incorrect. The C-peptide test assesses insulin production by the pancreas and is not specifically used to assess glucose clearance.
