Difficulty: EasyPharmacological and Parenteral Therapies

A healthcare provider prescribes an intravenous piggyback (IVPB) infusion of cefazolin 1 gram in 50 mL50\text{ mL} of 0.9% sodium chloride to be administered over 30 minutes30\text{ minutes}. The nurse should set the intravenous infusion pump to deliver how many mL/hr\text{mL/hr}? Record your answer using a whole number.

Answer: 100 mL/hr

Answer

100
To determine the correct infusion pump setting in mL/hr, divide the total volume to be infused (50 mL) by the total time in minutes (30 minutes), and then multiply by 60 to convert minutes to hours. (50 mL / 30 min) * 60 min/hr = 100 mL/hr.

Step-by-Step Solution

1
Identify the total volume of the medication to be infused.
Total volume = 50 mL.
The medication is diluted in a specific amount of fluid that needs to be delivered.
2
Identify the prescribed duration of the infusion.
Time = 30 minutes.
The infusion pump rate must be calculated based on the total time over which the medication should be administered.
3
Set up the equation to calculate the infusion pump rate in mL/hr.
Rate (mL/hr) = (50 mL / 30 minutes) * 60 minutes/1 hour.
Infusion pumps are programmed in mL/hr, so minutes must be converted to hours.
4
Perform the calculation.
100
Multiplying (50/30) by 60 yields exactly 100 mL/hr, which is a whole number.
