A patient asks how metformin works to control blood sugar. What is the nurse's best response?
"Metformin stimulates the pancreas to produce more insulin."
"Metformin increases the absorption of glucose in the intestines."
"Metformin decreases glucose production in the liver and improves insulin sensitivity."
"Metformin decreases the breakdown of fat in the body."
The Correct Answer is C
A. Metformin does not stimulate the pancreas to produce more insulin; that action is characteristic of sulfonylureas.
B. Metformin does not increase the absorption of glucose in the intestines; rather, it works by reducing the amount of glucose released into the bloodstream.
C. Metformin primarily decreases glucose production in the liver and improves insulin sensitivity in peripheral tissues, which helps lower blood sugar levels. This makes it effective for managing type 2 diabetes.
D. While metformin can have effects on fat metabolism, its primary action is not to decrease fat breakdown but to manage blood glucose levels.
