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?

Correct answers: C Rationale: A. 1300 represents an elapsed time of only 6 hours from the start of the infusion at 0700. At a flow rate of 100 mL/hr, only 600 mL would have been administered. This leaves 400 mL remaining in the primary bag. B. 1100 indicates that only 4 hours have passed since the initiation of the intravenous therapy. At the prescribed rate, the volume infused would be 400 mL. The bag would still contain 600 mL, necessitating no replacement at this early hour. C. 1700 is the correct time because 10 hours must elapse to infuse 1,000 mL at 100 mL/hr. Starting at 0700 and adding 10 hours reaches 1700. This calculation ensures the maintenance of continuous fluid resuscitation without interrupting the flow. D. 2200 occurs 15 hours after the initial hang time of the lactated Ringer's solution. By this time, 1,500 mL would have been required, exceeding the bag capacity. The 1,000 mL reservoir would have been completely depleted 5 hours prior.
