A postoperative client has an order for intravenous pantoprazole. The medication is prepared in a 100 mL100\text{ mL} bag of 0.9%0.9\% sodium chloride and needs to be infused over 15 minutes15\text{ minutes}. At what rate, in mL/hr\text{mL/hr}, will the nurse set the infusion pump?

Cevap: 400 mL/hr

Cevap

The nurse should set the infusion pump to 400 mL/hr400\text{ mL/hr}.
To determine the correct IV pump setting in mL/hr\text{mL/hr}, the nurse must calculate the hourly rate of the infusion. Because the medication is ordered to infuse over a fraction of an hour (15 minutes15\text{ minutes} is 0.25 hours0.25\text{ hours}), dividing the total volume (100 mL100\text{ mL}) by the time in hours (0.25 hours0.25\text{ hours}) yields 400 mL/hr400\text{ mL/hr}. Alternatively, setting up a direct proportion (100 mL100\text{ mL} in 15 minutes15\text{ minutes} is equivalent to X mLX\text{ mL} in 60 minutes60\text{ minutes}) also results in 400 mL/hr400\text{ mL/hr}.

Adım Adım Çözüm

1
Identify the total volume of fluid to be infused.
100 mL100\text{ mL}
The infusion pump rate calculation requires the total volume of the medication bag.
2
Convert the infusion time from minutes to hours.
15 minutes÷60=0.25 hours15 \text{ minutes} \div 60 = 0.25\text{ hours}
Intravenous infusion pumps are programmed in mL/hr\text{mL/hr}, so the time must be standardized to hours.
3
Calculate the final infusion rate by dividing the volume by the time in hours.
100 mL÷0.25 hours=400 mL/hr100\text{ mL} \div 0.25\text{ hours} = 400\text{ mL/hr}
The formula for IV pump rate is Total Volume (mL) divided by Total Time (hr).
