A patient is ordered a continuous heparin infusion at 16 units/kg/hr. The patient weighs 176lbs. Heparin is supplied in 50000 units/500mL. At what rate will the nurse set the pump?
Correct Answer: 12.8
1. Convert pounds to kilograms:
176 lbs/2.20462 kg =80 kg
2. Calculate the desired heparin infusion rate:
16 units/kg/hr x 80kg = 1280 units/hr
3. Determine the concentration of heparin in the solution:
50000 units / 500 mL = 100 units/mL
4. Calculate the infusion rate in millilitres per hour:
1280 units/hr / 100 units/mL =12.8 mL/hr
