Question

Your patient is ordered cephalothin 750mg in 50mL NS IVPB to infuse over 30 minutes. How many ml per hour will you set on the pump?

Answer 1

To set the correct rate on the IV pump, calculate the rate as the total volume times sixty divided by the infusion time in minutes, leading to setting the pump at 100 ml per hour for a 30-minute infusion of 50mL.

Step-by-step explanation:

To determine how many ml per hour you will need to set on the IV pump for your patient who is ordered cephalothin 750mg in 50mL NS to infuse over 30 minutes, you use the formula:

rate (ml/hour) = total volume (ml) × (60 minutes/hour) / infusion time (minutes)

Using this formula:

rate = 50 mL × (60 / 30) = 100 ml per hour

You would need to set the IV pump at 100 ml per hour to deliver the medication over the prescribed 30-minute period.
