A nurse is preparing a heparin infusion for a client who was admitted to the facility with deep-vein thrombosis.

The prescription reads: 25,000 units of heparin in 0.9% sodium chloride 250 mL to infuse at 800 units/hr. What should be the infusion pump rate?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["8"]

Step 1 is: Calculate the total units of heparin in the bag, which is 25,000 units.

Step 2 is: Divide the total units by the total volume to find the units per mL, which is (25,000 units ÷ 250 mL) = 100 units/mL.

Step 3 is: Divide the desired units per hour by the units per mL to find the mL/hr, which is (800 units/hr ÷ 100 units/mL) = 8 mL/hr. So, the infusion pump rate should be set at 8 mL/hr.
