Question

The surgeon orders a medication 1.5 gms IV. The pharmacy delivers the medication as 1.5 grams in 150 mL IV solution to be infused over 90 minutes. The rate of the infusion is____mL/hr.

Answer 1

The infusion rate for a medication delivered in a 150 mL IV solution over 90 minutes should be set to 100 mL/hr to properly administer the medication in the prescribed time.

Step-by-step explanation:

To calculate the infusion rate of the medication, we can use a simple ratio and proportion based on the information provided. The pharmacy sends a 1.5 grams medication in 150 mL IV solution to be administered over 90 minutes. The goal is to find the correct rate in mL/hr to complete the infusion in the specified time.

First, we determine the infusion time in hours, since the rate is required in mL/hr. There are 60 minutes in an hour, so 90 minutes is equivalent to 1.5 hours. Using this conversion, we set up the ratio as the total volume to be infused over the total time in hours

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

Plugging in the numbers:

150 mL / 1.5 hours = 100 mL/hr

This is the rate at which the IV infusion should be set to deliver the medication over the specified time.

To infuse 1.5 grams of medication delivered in a 150 mL IV solution over 90 minutes, the IV pump should be set to an infusion rate of 100 mL/hr.
