At 10 a.m. the nurse measures the amount of total parenteral nutrition solution left in the 3,000 mL infusion bag. Running at a rate of 100 ml/hr, the nurse determines that 1500 ml of the solution remain. The TPN was infused at noon the previous day. The nurse knows that the change of infusion bag must be scheduled:

Tomorrow at 1:00 a.m.
Today at 7 p.m.
Today at 10 p.m.
Midnight
