The nurse has an order to administer 100 units of regular insulin in 500 mL of 0.9% NS to infuse at 12 units per hour. The nurse should program the IV pump to deliver how many mLs per hour?

The nurse should set the IV pump to 60 mL/hr.

Set up a proportion to solve for milliliters per hour: 100 units/500 mL = 12 units/x mL . Solve for x : 100x = 500(12) . 100x = 6000 . x = 60 mL/hr . The IV pump should deliver 60 mL per hour.
