The newly diagnosed patient with type 2 diabetes has been prescribed metformin (Glucophage). What should the nurse tell the patient to best explain how this medication works?
Increases insulin release from the pancreas, inhibits glucagon secretion, and decreases gastric emptying.
Reduces glucose production by the liver and enhances insulin sensitivity.
Slows the absorption of carbohydrate in the small intestine.
Increases insulin production from the pancreas.
The Correct Answer is B
Choice A rationale: Metformin does not significantly affect insulin release from the pancreas or glucagon secretion but reduces glucose production by the liver and enhances insulin sensitivity in tissues.
Choice B rationale: Metformin primarily works by reducing glucose production in the liver and improving the body's response to insulin, thereby lowering blood sugar levels.
Choice C rationale: Metformin does not notably slow carbohydrate absorption in the small intestine.
Choice D rationale: Metformin does not directly increase insulin production from the pancreas.
