A 65-year-old adult patient weighing 80 kg is prescribed a continuous heparin infusion. The order is for 18 units/kg/hour. The pharmacy supplies heparin in a concentration of 25,000 units/500 mL. Determine the total units of heparin the patient should receive per hour.
The Correct Answer is ["1440"]
To calculate the total units of heparin per hour:
Multiply the patient’s weight (80 kg) by the dosage (18 units/kg/hour):
80 kg × 18 units = 1440 units/hour.
This means the patient should receive 1440 units of heparin per hour.
