What is the nurse's best response regarding insulin use for the client diagnosed with diabetes type 2?

The choice that states that "Metformin helps your body use insulin more effectively" is correct because it highlights the role of metformin in the management of type 2 diabetes. Metformin is often the first-line medication prescribed for individuals with this condition. It works primarily by increasing insulin sensitivity in peripheral tissues, such as muscle and fat, which allows for better glucose uptake and usage. This improvement in insulin dynamics can help manage blood sugar levels effectively.

In the context of diabetes management, insulin is not the only option. Various oral medications, lifestyle changes, and supplemental therapies, such as metformin, can often control blood glucose levels in patients with type 2 diabetes before resorting to insulin therapy. Starting insulin right away is not typically the first step unless there is a compelling reason, such as significant hyperglycemia or other factors. Avoiding discussion of treatment options undermines the collaborative aspect of healthcare, which is crucial for empowering patients to participate in their care.
