Using an IV infusion system that delivers 60 drops/mL, the nurse hangs a 1000-mL bag of D5W, which the physician has ordered to infuse at 80 mL/hr. It is now 10 AM. The nurse anticipates that the IV will need to be changed at:
1. 6 PM.
2. 8 PM.
3. 8:30 PM.
4. 10:30 PM.

1000 mL (whole volume)/80 mL (volume infused per hour) = 12.5 hours. 10:00 AM + 12.5 hours = 10:30 PM.

However, your patient continues to state, "I know I do not need to spend my time doing all this because I will be fine once I get out from under all this stress."
