Explanation / Answer

Order : heparin, infuse 500 units/hr

Avaliable : heparin 25,000 units in 250 mL. supplied IV bag

Now

Flow rate in ( mL / hr ) =( (500 units / hr)/(25,000 units) ) x 250 mL

Flow rate in ( mL / hr ) = 5 mL / hr

if 20 drops is = 1 mL

       ?            = 250 mL

no. of drops = 250 x 20

                   = 5000 drops
