A client is prescribed 250 mg of metformin. The pharmacy supplies 500 mg pre- scored tablets of metformin. How should the nurse administer the medication to the client?

Administer one half tablet

Administer two tablets

Administer one tablet

Administer one-and-a-half tablets

Answer and Explanation

The Correct Answer is A

Administer one half tablet. To find the amount of tablets to administer, use the formula: (ordered dose / available dose). In this case, (250 mg / 500 mg) = 0.5 tablet. Since the tablet is pre-scored, it can be easily split in half.

Metformin is a medication that belongs to a class of drugs called biguanides. It is used to treat type 2 diabetes by lowering blood sugar levels and improving insulin sensitivity. Metformin works by reducing the amount of glucose produced by the liver and increasing the uptake of glucose by the muscles and other tissues.

Metformin can also help prevent or delay the onset of diabetes complications, such as heart disease and kidney damage.
