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.
Correct Answer is B
Explanation
To calculate the infusion rate in mL/hr, we need to divide the total volume to be infused by the time for infusion and convert the units appropriately.
First, we need to convert the time of infusion from hours to minutes, since most IV pumps use minutes as the time unit.
2 hours x 60 minutes/hour = 120 minutes Next, we can calculate the infusion rate:
500 mL ÷ 120 minutes = 4.17 mL/minute
To convert mL/minute to mL/hour, we multiply by 60:
4.17 mL/minute x 60 minutes/hour = 250 mL/hour
Therefore, the correct answer is B. 250 mL/hr. The nurse should set the IV pump to deliver the LR infusion at a rate of 250 mL/hr to infuse 500 mL over 2 hours.
