A patient is ordered a continuous heparin infusion 18 units/kg/hr. The patient weighs 220 lbs. The medication is supplied as 25.000 units/250 ml. At what rate should the nurse set the pump?
The Correct Answer is ["18"]
To calculate the infusion rate, we'll follow these steps:
Convert patient weight to kilograms:
220 lbs ÷ 2.2 lbs/kg = 100 kg
Calculate desired heparin dose:
18 units/kg/hr × 100 kg = 1800 units/hr
Determine infusion rate in mL/hr:
(1800 units/hr) / (25000 units/250 mL) = 18 mL/hr

Correct Answer is ["2.0"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Determine the total daily dosage:
5 mg/kg/day × 120 kg = 600 mg/day
Calculate the dosage per dose:
600 mg/day ÷ 3 doses = 200 mg/dose
Determine the volume to be administered:
200 mg ÷ 100 mg/mL = 2.0 mL
Correct Answer is ["12.8"]
Explanation
To calculate the infusion rate, we'll follow these steps:
Convert patient weight to kg:
176 lbs ÷ 2.2 lbs/kg = 80 kg
Calculate desired heparin dose:
16 units/kg/hr × 80 kg = 1280 units/hr
Determine infusion rate in mL/hr:
(1280 units/hr) / (50000 units/500 mL) = 12.8 mL/hr
