A nurse is caring for a client is who has a deep vein thrombosis and is prescribed heparin by continuous lV infusion at 1,200 units/hr. Available is heparin 25,000 units 250 mL D5W. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Given: Desired infusion rate: 1,200 units/hr Available concentration: Heparin 25,000 units in 250 mL DSW To find: Infusion rate (mL/hr) Step 1: Calculate the concentration of heparin in mL/hr Concentration (units/mL) = Total units / Total volume Concentration (units/mL) = 25,000 units / 250 mL = 100 units/mL Step 2: Calculate the infusion rate in mL/hr Infusion rate (mL/hr) = Desired infusion rate (units/hr) / Concentration (units/mL) Infusion rate (mL/hr) = 1,200 units/hr / 100 units/mL = 12 mL/hr
