The physician ordered heparin 1200 units/hour. Heparin is available as 40,000 units in 1000 mL D5W. What is the correct IV flow rate in milliliters per hour?
Answer
Volume of fluid in ml=1000ml/hour
Total number of units in volume=40000 units
Unit in dose=1200units
Time=1hr
So iticalculated by using
=Volume of IV fluid in ml/Total number of units in volume×unit in dose/time (hr)
ml/hr=1000ml/40000units×1200/1hr
=30ml/hr
The IV flow rate is 30ml/hr
