A client with deep vein thrombosis (DVT) is receiving a continuous IV infusion of heparin sodium 20,000 units in 5% dextrose injection 500 mL at the rate of 25 mL/hour. How many units of heparin should the client receive in 12 hours? (Enter numeric value only.)

Step 1: Identify the rate of infusion. 25 mL/hour Step 2: Identify the concentration. 20,000 units/500 mL Step 3: Calculate the amount of heparin per mL. 20,000 ÷ 500 = 40 units/mL Step 4: Calculate the amount of heparin per hour. 25 × 40 = 1,000 units/hour Step 5: Calculate the total amount of heparin in 12 hours. 1,000 × 12 = 12,000 units
