A continuous heparin infusion is to begin at 15 units/kg/hr for a client weighing 82 kg. Available: 25,000 units of heparin in 250 mL D5W. Calculate the mL/hr. (the pump is capable of delivering in tenths of an mL).

Given: Ordered dose of Heparin: 15 units/kg/hr Patient weight: 82 kg Total Heparin in solution: 25,000 units Volume of solution: 250 mL Step 1: Calculate the total dose of Heparin in units/hr: Total dose (units/hr) = Ordered dose (units/kg/hr) x Patient weight (kg) Total dose (units/hr) = 15 units/kg/hr x 82 kg Total dose (units/hr) = 1230 units/hr Step 2: Calculate the concentration of Heparin in the solution: Concentration (units/mL) = Total Heparin (units) / Volume of solution (mL) Concentration (units/mL) = 25,000 units / 250 mL Concentration (units/mL) = 100 units/mL Step 3: Calculate the infusion rate in mL/hr: Infusion rate (mL/hr) = Total dose (units/hr) / Concentration (units/mL) Infusion rate (mL/hr) = 1230 units/hr / 100 units/mL Infusion rate (mL/hr) = 12.3 mL/hr
