The nurse is preparing a heparin drip for a client who weights 176 lb. The available heparin is infusion 20,000 units in 1,000 ml 0.9% sodium chloride. The order is to deliver a bolus then initiate a drip at 18 units/kg/hr. What will the nurse program the infusion pump to deliver? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Convert the patient's weight from pounds (lb) to kilograms (kg). Patient weight (kg) = 176 lb / 2.2 lb/kg = 80 kg. Calculate the total units per hour. Total units/hr = Patient weight (kg) x Ordered dose (units/kg/hr) = 80 kg x 18 units/kg/hr = 1440 units/hr. Calculate the concentration of the available heparin. Concentration (units/mL) = Total units / Total volume = 20,000 units / 1,000 mL = 20 units/mL. Calculate the infusion rate in milliliters per hour (mL/hr). Infusion rate (mL/hr) = Total units per hour / Concentration = 1440 units/hr / 20 units/mL = 72 mL/hr.
