A nurse is caring for a client who is receiving IV dextrose 5% in 0.9% sodium chloride at 75 mL/hr. When the nurse checks the client's IV bag at 0700, 300 mL remain in the bag.
At what time should the nurse hang a new bag of IV fluid? (Use the military format, four-digit number to enter the time.)
The Correct Answer is ["1100"]
The correct answer is 1100.
Calculation: The current time is 0700 and there are 300 mL remaining in the bag. The IV is infusing at a rate of 75 mL/hr. Therefore, 300 mL ÷ 75 mL/hr = 4 hours. Adding 4 hours to the current time of 0700 gives 1100.
