The nurse prepares to administer heparin to be infused at 1000 units/hr. The heparin solution comes in 25.000 units in 250 mL D5W. How many mL/hr should the nurse set the IV pump? Round to the nearest whole number.

Step 1: Identify concentration Concentration = 25,000 units ÷ 250 mL = 100 units/mL Step 2: Use the formula mL/hour = Desired dose (units/hr) ÷ Concentration (units/mL) Step 3: Insert values = 1000 ÷ 100 Step 4: Calculate = 10 mL/hr Final Answer: 10
