An IV of 1000 mL 1/2 NS with 20,000 units of heparin is infusing at 40 mL / hr. How many units of heparin is the patient receiving each hour? ____________
CALCULATIONS :
Concentration of IV = Total amount of drug/Total volume
=20,000 unit of heparin /1000 mL NS
=20 units of heparin/mL
IV rate =dose desired /concentration of IV
Therefore dose desired =concentration of IV × IV rate
=20×40 mL/hr
= 800 units/hr
ANSWER :
800 units/hr
