Question
Use military time in calculating the completion time of the following IV flow problems. The doctor orders 1 L Lactated Ringer's to infuse at 80 mL / hr. The nurse starts the IV at 2330. At 0330, the IV infiltrates. The nurse restarts the IV at 0400, at the same rate. Starting with the amount of IV fluid left at 0300, calculate the new infusion time and the completion time of the IV. Write your answers as 2 comma separated numbers for infusion (in hours) and completion times (military time) (e.g. 5, 2030)
Explanation / Answer
Given:
1 L= 1000 ml of Lactated Ringer's to infuse.
Rate of Infusion=80ml/hr
Case 1: The nurse starts the IV at 2330 till 0330.
The rate of Infusion is 80ml/hr.
Case 2:
Since the nurse restarts the IV at 0400 with the amount of IV left at 0300, we need the amount of IV fluid at 0300. The given table shows the amount of IV fluid at different time intervals till 0300:-
Number of hours
Volume
consumed
We need to calculate the infusion time and the completion time of the IV:
1). Infusion time: Time taken by the fluid to complete or elapse.
infusion time (hr) = total volume (mL) ÷ flow rate (mL/hr)
= 720÷80
=9 hour.
Therefore, Infusion time will be 9 hours.
2). Completion time: Completion time is the time of the day at which the fluid finished.
As the nurse started the IV at 0400, the IV fluid took 9 hours to finish, So adding 9 hours to 0400, we get the time as,
0400+0900=1300.
Therefore the completion time of fluid is 1300.
