The healthcare provider prescribes heparin 18 units/kg/hr IV for a client who weighs 154 Ibs to prevent deep vein thrombosis (DVT). The premixed IV solution is labeled "Heparin Sodium 20,000 Units in Dextrose 5% in Water (D5W) 500 mL". The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Calculation Convert Patient Weight from Pounds (lbs) to Kilograms (kg) Weight in kg = 154 lbs / 2.2 kg/lb = 70 kg Calculate the Ordered Dose in Units per Hour (Units/hr) Ordered Dose (Units/hr) = 18 units/kg/hr x 70 kg = 1,260 units/hr Determine the Concentration of the IV Solution (Units/mL) Concentration (Units/mL) = 20,000 units / 500 mL = 40 units/mL Calculate the Flow Rate (mL/hr) Flow Rate (mL/hr) = Ordered Dose (Units/hr) / Concentration (Units/mL) = 1,260 units/hr / 40 units/mL = 31.5
