Correct Answer is A

Explanation

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.

A. 75 mL/hr B. 150 mL/hr C. 300 mL/hr D. 450 mL/hr

Correct Answer is C

Explanation

To calculate the rate per hour, divide the amount of magnesium sulfate to be administered by the concentration of magnesium sulfate in the IV bag:

6 grams ÷ 40 grams = 0.15

Then, multiply the result by the volume of the IV bag, which is usually 1000 mL: 0.15 x 1000 mL = 150 mL

This is the amount of fluid that contains 6 grams of magnesium sulfate. To administer this amount over 30 minutes, multiply by 2 to get the rate per hour:

150 mL x 2 = 300 mL/hr.
