Final answer:
Metformin (Glucophage) reduces glucose production by the liver and enhances insulin sensitivity, allowing glucose to enter cells for energy.
Step-by-step explanation:
What should the nurse tell the patient to best explain how this medication works?
The nurse should explain that metformin (Glucophage) works by reducing glucose production by the liver and enhancing insulin sensitivity.
Metformin helps to lower blood glucose levels by decreasing the amount of glucose produced by the liver. It also makes the body's cells more responsive to insulin, allowing glucose to enter the cells and be used for energy instead of staying in the bloodstream.
