Question

A multiple sclerosis patient has an order for 1 g of methylprednisolone in 500 mL of NS to run over 4 hours. At what rate will the final solution be administered?

Answer 1

To administer a methylprednisolone IV dose of 1g in 500 mL of NS over 4 hours, the infusion should be set to a flow rate of 125 mL per hour.

Step-by-step explanation:

The student is asking about an intravenous (IV) medication dose calculation, which is required to determine the appropriate infustion rate for a patient's IV medication order of methylprednisolone. Specifically, the question pertains to administering 1g of methylprednisolone in 500 mL of normal saline (NS) over a 4-hour period. To calculate the flow rate:

Flow rate (mL/hr) = Total volume (mL) / Total time (hrs)

Flow rate = 500 mL / 4 hrs = 125 mL/hr

Therefore, the IV solution should be administered at a rate of 125 mL per hour.

To determine the rate at which the final solution will be administered, we need to calculate the infusion rate. The order is for 1 g of methylprednisolone to be diluted in 500 mL of normal saline (NS) and to run over 4 hours.

First, we need to convert 1 g to mg by multiplying it by 1000, which gives us 1000 mg of methylprednisolone. Next, we can calculate the infusion rate by dividing the volume (500 mL) by the time (4 hours). This gives us a rate of 125 mL/hour. Therefore, the final solution will be administered at a rate of 125 mL/hour.
