A nurse is caring for a client who is receiving lactated Ringer's at a rate of 100 mL/hr. The nurse initiates a 1,000 mL bag of solution at 0700. The nurse should expect to hang another bag of IV solution at which of the following times?
1300
1100
1700
2200
The Correct Answer is A
A. At a rate of 100 mL/hr, a 1,000 mL bag will infuse over 10 hours. Starting at 0700, the infusion will complete at 1700, but the nurse typically hangs a new bag 1 hour before completion to avoid delays. 1300 is 6 hours in, leaving 400 mL; it allows enough time to prepare and change bags proactively.
B. 1100 is too early.
C. 1700 is too late – the bag would be empty by then.
D. 2200 is unrelated to the infusion timeline.
