Difficulty: EasyPharmacological and Parenteral Therapies

A nurse is preparing to administer an intravenous piggyback (IVPB) of cefazolin 1 gram1 \text{ gram} in 50 mL50 \text{ mL} of 0.9%0.9\% sodium chloride to a client with a surgical site infection. The medication is prescribed to infuse over 30 minutes30 \text{ minutes}. At what rate in mL/hr\text{mL/hr} should the nurse set the electronic infusion pump? Record your answer as a whole number.

Answer: 100 mL/hr

Answer

The electronic infusion pump should be set to 100 mL/hr.
To determine the correct rate for an electronic infusion pump in mL/hr, divide the total volume in mL by the total time in hours. Converting 30 minutes to 0.5 hours and dividing 50 mL by 0.5 hours results in an infusion rate of 100 mL/hr.

Step-by-Step Solution

1
Identify the total volume of the infusion.
50 mL50 \text{ mL}
The rate calculation requires the total volume of fluid to be administered.
2
Convert the prescribed infusion time from minutes to hours.
30 minutes÷60 minutes/hour=0.5 hours30 \text{ minutes} \div 60 \text{ minutes/hour} = 0.5 \text{ hours}
Electronic infusion pumps are typically programmed in milliliters per hour (mL/hr), so the time must be expressed in hours.
3
Calculate the infusion rate by dividing the total volume by the time in hours.
50 mL÷0.5 hours=100 mL/hr50 \text{ mL} \div 0.5 \text{ hours} = 100 \text{ mL/hr}
This calculation yields the required pump setting in mL/hr.
