A client who is newly diagnosed with type 2 diabetes mellitus (DM) receives a prescription for metformin 500 mg PO twice daily. Which statement(s) should the nurse include in this client’s teaching plan? (Select all that apply.)

Choice A: Taking metformin with the morning and evening meal is a correct statement for the nurse to include, as this can improve the absorption and effectiveness of metformin and reduce the risk of gastrointestinal side effects. Therefore, this is a correct choice.Choice B: Using sliding scale insulin for frequent blood glucose elevations is not a correct statement for the nurse to include, as this is not recommended for clients with type 2 DM who are taking metformin. This can cause hypoglycemia and complicate the management of blood glucose levels. This is an incorrect choice.Choice C: Recognizing signs and symptoms of hypoglycemia is a correct statement for the nurse to include, as this can help the client identify and treat low blood glucose levels, which can occur with metformin use or other factors such as exercise, fasting, or alcohol intake. Therefore, this is another correct choice.Choice D: Reporting persistent polyuria to the health care provider is a correct statement for the nurse to include, as this can indicate poor glycemic control or a complication of DM such as diabetic ketoacidosis or nephropathy. Therefore, this is another correct choice.Choice E: Taking an additional dose for signs of hyperglycemia is not a correct statement for the nurse to include, as this can cause overdose or toxicity of metformin, which can lead to lactic acidosis and renal failure. This is another incorrect choice.
