1.       100ml of IV is ordered over 6 hours. The drop factor is 20. The IV has been running for 4 hours and 400 mls remain in the bag. How many drops/per minutes are required thus the IV infusion completes at the needed time?

2.       One IV back containing 400 mg of medication in 100 mls is to be infused to Jack over 120mins. What rate should you set the IV pump at?

3.       One IV back have 130 mg of drug in 250 mls is to be infused over half hour. What rate should you set the IV pump at?

4.       1000 ml IV  is ordered over 240 mins. The drop factor is 30. The IV has been running for 120mins and still 600mls remain in the flask. How many drops/per minute are required so that the IV finishes at the needed time?
