A client with severe gastroenteritis requires intravenous rehydration. The treatment plan includes 1,000 mL1,000\text{ mL} of 0.9%0.9\% sodium chloride to run over a 4-hour4\text{-hour} period. At what rate in mL/hr\text{mL/hr} should the nurse program the infusion pump? (Record your answer using a whole number.)

Cevap: 250 mL/hr

Cevap

The nurse should program the infusion pump to deliver 250 mL/hr250\text{ mL/hr}.
To determine the correct hourly infusion rate for an IV pump, divide the total volume of fluid to be infused (1,000 mL1,000\text{ mL}) by the total duration of the infusion (4 hours4\text{ hours}). The resulting quotient (250 mL/hr250\text{ mL/hr}) is the correct programming rate.

Adım Adım Çözüm

1
Identify the total volume to be infused.
1,000 mL1,000\text{ mL}
The total volume serves as the numerator in the infusion rate formula.
2
Identify the total time for the infusion.
4 hours4\text{ hours}
The pump rate requires a time denominator in hours.
3
Divide the total volume by the total time.
1,000 mL÷4 hours=250 mL/hr1,000\text{ mL} \div 4\text{ hours} = 250\text{ mL/hr}
This calculation yields the exact volume to be delivered each hour.
