The nurse receives a report at 0700 on a client who has 700 mL of IV fluid left in the bag. The IV is running at 100 mL per hour. At what time should the nurse expect to change the bag (military time)?
1400
1600
1500
0200
The Correct Answer is A
Determine the remaining volume and the flow rate:
Remaining volume: 700 mL
Flow rate: 100 mL/hour
Calculate the time it will take to infuse the remaining volume:
Time (hours) = Remaining Volume / Flow Rate
Time = 700 mL / 100 mL/hour
Time = 7 hours
Determine the time the bag will be empty:
The nurse receives the report at 0700 (7:00 AM).
Add the 7 hours to 0700: 0700 + 7 hours = 1400

Correct Answer is ["5"]
Explanation
Determine the concentration of the insulin solution:
There are 100 units of insulin in 100 mL of IV fluid.
Concentration = 100 units / 100 mL = 1 unit/mL
Calculate the volume (in mL) needed per hour:
The client needs 5 units per hour.
Since the concentration is 1 unit/mL, this means the client needs 5 mL per hour.
Set the IV pump:
The IV pump should be set to infuse at 5 mL/hr.
Correct Answer is ["5.5"]
Explanation
Determine the concentration of the insulin solution:
You have 75 units of insulin in 150 mL of normal saline.
Concentration = 75 units / 150 mL = 0.5 units/mL
Use the infusion rate to calculate the units of insulin per hour:
The client is receiving 11 mL per hour.
Units per hour = Infusion rate (mL/hr) x Concentration (units/mL)
Units per hour = 11 mL/hr x 0.5 units/mL = 5.5 units/hr
