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.)
A.
Take metformin with the morning and evening meal.
B.
Use sliding scale insulin for frequent blood glucose elevations.
C.
Recognize signs and symptoms of hypoglycemia.
D.
Report persistent polyuria to the health care provider.
E.
Take an additional dose for signs of hyperglycemia.
The Correct Answer and Explanation is:
The correct answers are:
A. Take metformin with the morning and evening meal.
D. Report persistent polyuria to the health care provider.
Here’s an explanation for each option:
A. Take metformin with the morning and evening meal.
Metformin is commonly prescribed for type 2 diabetes mellitus to help control blood glucose levels. It is recommended to take metformin with meals to reduce the risk of gastrointestinal side effects such as nausea, vomiting, and diarrhea. Taking metformin with food can help to mitigate these side effects and improve the medication’s tolerance. For a typical prescription of 500 mg twice daily, it’s advised to take it with the morning and evening meals. This practice helps to maintain steady blood glucose levels and minimize gastrointestinal discomfort.
B. Use sliding scale insulin for frequent blood glucose elevations.
This statement is not specifically applicable to metformin as it pertains to insulin therapy. Metformin is an oral hypoglycemic agent that does not involve sliding scale insulin, which is a method used to adjust insulin doses based on blood glucose readings. Sliding scale insulin is typically used for patients on insulin therapy rather than those on metformin alone. Therefore, this option does not directly relate to the management of a client taking metformin.
C. Recognize signs and symptoms of hypoglycemia.
Metformin alone rarely causes hypoglycemia because it does not directly stimulate insulin release from the pancreas. Hypoglycemia is more commonly associated with medications that increase insulin levels or those that cause excessive insulin release. However, if metformin is used in conjunction with other medications that do cause hypoglycemia (such as insulin or sulfonylureas), it’s essential for patients to recognize signs of low blood sugar, such as shakiness, sweating, and confusion. Since the question specifies that the client is only on metformin, this precaution is not the primary concern but is still relevant if additional medications are prescribed later.
D. Report persistent polyuria to the health care provider.
Polyuria, or frequent urination, can be a symptom of poorly controlled diabetes. Persistent polyuria might indicate that the client’s blood glucose levels are not well managed, which could lead to complications. Reporting such symptoms to the healthcare provider is crucial as it may necessitate adjustments in the diabetes management plan, including medication review or additional tests.
E. Take an additional dose for signs of hyperglycemia.
This is incorrect as it is not appropriate to adjust the dose of metformin on your own based on symptoms of hyperglycemia. Changes in medication dosage should be done under the guidance of a healthcare provider. The standard practice is to follow the prescribed dosage and schedule and consult with the provider if there are concerns about blood glucose levels.
In summary, the client should take metformin with meals to reduce side effects and report any persistent symptoms such as polyuria, which could indicate inadequate glucose control.
