1. A demure physician orders 63 mg of MicroMenace to be administered IV in 1250 mL of LR over a 12 hour period. In preparing the order you use MicroMenace 46 mg in 2.8 mL and your IV bag contains conventional overfill. What infusion rate in mL/min should the patient receive.  Answer to the nearest tenth mL/min.

Answer explanation

Need to add up all the total mls in the bag. Remember conventional overfill is 10% of the bag.

(63 mg * 2.8 ml)/46 mg = 3.834782609 ml of drug

1250 ml + 125 ml + 3.834782609 ml = 1378.834783 ml /(12 hours *60 mins/hr) = 1.9 ml/min
