The doctor orders your patient to start an IV Heparin drip at 16 units/kg/hr and to administer a loading bolus dose of 60 units/kg IV before initiation of the drip. You're supplied with a Heparin bag that reads 12,500 units/250 mL. The patient weighs 198 lbs. What is the flow rate you will set the IV pump (mL/hr)?

A. This is incorrect. B. This is incorrect. C. This is incorrect. D. Step 1: Convert the patient’s weight from pounds to kilograms Weight (kg) = 198 ÷ 2.2 Weight (kg) ≈ 90 kg Step 2: Calculate the Heparin drip rate in units/hr Drip rate (units/hr) = 16 units/kg/hr × 90 kg Drip rate = 1,440 units/hr Step 3: Determine the concentration of the Heparin bag Concentration = 12,500 units ÷ 250 mL Concentration = 50 units/mL Step 4: Calculate the flow rate in mL/hr Flow rate (mL/hr) = Drip rate ÷ Concentration Flow rate = 1,440 ÷ 50 Flow rate = 28.8 mL/hr Step 5: Match the calculated flow rate to the options 28.8 mL/hr Final Answer: D. 28.8 mL/hr
