Your patient is to receive 2 G vancomycin over 2 hours. If the medication comes in 250 mL normal saline, what rate will the IV run?

To calculate the IV infusion rate for the 250 mL of normal saline that will be used to administer 2 g of vancomycin over 2 hours, you need to divide the total volume of the IV solution by the total time in hours.

The total volume of the infusion is 250 mL, and the total time of the infusion is 2 hours.

To find the infusion rate, use the formula:

Infusion rate (mL/hr) = Total volume (mL) / Total time (hr)

Plugging in the values:

Infusion rate = 250 mL / 2 hr = 125 mL/hr

This means the correct infusion rate at which the IV will run is 125 mL/hr. This calculation confirms that the correct answer is indeed the one that reflects this rate. Monitoring this rate properly ensures the medication is delivered in a timely manner, providing effective treatment while minimizing the risks of complications associated with IV administration.
