A client is to receive a continuous Heparin infusion at s00 units per hour. Pharmacy supplies Heparin in a concentration of 25,000 units per 250mL of NSS. Calculate the rate at which the nurse should set the infusion pump.

Step 1: Determine the concentration of Heparin in units per mL. 25,000 units ÷ 250 mL = 100 units per mL Result: 100 Step 2: Determine the rate in mL per hour needed to deliver 500 units per hour. 500 units ÷ 100 units per mL = 5 mL per hour Result: 5 mL per hour The nurse should set the infusion pump to deliver at a rate of 5 mL per hour.
