A primary healthcare provider prescribes 1.5 L of normal saline (NS) to be given over 24 hours for continuous intravenous (IV) infusion to a client who has diarrhea.
What should be the rate of infusion that is required to be set in the infusion pump?
41.7 mL/hr
83.3 mL/hr
20.8 mL/hr
62.5 mL/hr
The Correct Answer is D
To calculate the rate of infusion, we need to divide the total volume to be infused (1.5 L) by the total time of infusion (24 hours)
1.5 L = 1500 mL (since 1 L = 1000 mL)
Dividing 1500 mL by 24 hours gives us the rate of 62.5 mL/hr.

Correct Answer is A
Explanation
The flow rate of infusion is 125 mL/hr.
This answer is correct because it is based on a simple division and rounding calculation. The nurse should follow these steps to determine the flow rate of infusion:
1) Subtract the start time of the infusion from the end time of the infusion to get the duration of the infusion in hours and minutes, as follows:
15:45 - 06:57 = 8:48
Therefore, the infusion lasted for 8 hours and 48 minutes.
2) Convert the duration of the infusion to hours only by dividing the minutes by 60, since there are 60 minutes in 1 hour. Add this to the hours, as follows:
8 + (48 / 60) = 8.8
Therefore, the infusion lasted for 8.8 hours.
3) Divide the volume of the infusion by the duration of the infusion to get the flow rate in milliliters per hour, as follows:
1000 mL / 8.8 hr = 113.64 mL/hr
Therefore, the flow rate is 113.64 mL/hr.
4) Round the flow rate to the nearest whole number, as follows:
113.64 mL/hr ≈ 114 mL/hr
Therefore, the flow rate is approximately 114 mL/hr.
5) Adjust the flow rate to a standard value that can be set on an IV pump or gravity drip chamber, as follows:
114 mL/hr → 125 mL/hr
Therefore, the flow rate of infusion is 125 mL/hr.
