A nurse is caring for a client is who has a deep vein thrombosis and is prescribed heparin by continuous IV infusion at 1,200 units/hr. Available is heparin 25,000 units in 500 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.)

Answer and Explanation

The Correct Answer is ["24"]

- First, determine the concentration of the heparin solution. In this case, it's 25,000 units in 500 mL, which means there are 50 units per mL.

- Next, calculate the required rate to deliver 1,200 units per hour. Since the concentration is 50 units per mL, divide 1,200 units by 50 units/mL to find the required mL per hour.

- The calculation will be 1,200 units/hr ÷ 50 units/mL = 24 mL/hr.

- Since the question asks to round to the nearest tenth or whole number, and the result is a whole number, the IV pump should be set to deliver 24.0 mL/hr.

Answer =24
