Question

. A male patient weighing 76 kg is placed on heparin therapy for the prevention of deep vein thrombosis after surgery. (a) How many milliliters of a heparin injection containing 5000 units/mL should be administered for a loading dose of 80 units/kg? (b) What should be the infusion rate, in mL/h, using a solution that contains heparin 25,000 units/500 mL, to administer 18 units/kg/h?​

Answer 1

Step-by-step explanation:

a) 76 kg x 80 units/kg = 6,080 units. 6,080 units/5,000 units/mL = 1.216 mL of heparin injection should be administered for a loading dose of 80 units/kg.

b) 76 kg x 18 units/kg/h = 1,368 units/h. 1,368 units/h/25,000 units/500 mL = 0.10752 mL/h of heparin solution should be administered to administer 18 units/kg/h.
