Order: Begin a heparin drip per the facility’s protocol.
The patient’s weight is 154 lb.
Heparin Protocol
Bolus: Heparin 80 units/kg. Bolus vial contains 1,000 units per mL.
Infusion: Heparin 18 units/kg/h using a concentration of heparin 25,000
units in 250 mL of NS (100 units/mL).
Calculate the number of mL/hr required to deliver continuous infusion.
154 lb / 2.2 kg= 70
18 x 70 kg = 1,260 units per hr
