Administer heparin 1000 units per hour IV. The pharmacy supplies the heparin infusion as 25.000 units in 500 mL DSW. What will the IV pump be set to? (Include unit of measure with answer).

To calculate the IV pump rate, first determine the number of units needed per mL: 25,000 units / 500 mL = 50 units per mL. Then, divide the prescribed rate of 1000 units per hour by the units per mL to get the pump setting: 1000 units / 50 units per mL = 20 mL per hour. Therefore, the correct answer is 20 mL/hour.
Incorrect choices:
A: Incorrect, doesn't follow the correct calculation method.
B: Incorrect, doesn't consider the units per mL.
C: Incorrect, doesn't involve the prescribed rate.
D: Incorrect, doesn't calculate the infusion rate.
E: Incorrect, lacks the necessary calculation steps.
F: Incorrect, doesn't relate to the given information.
G: Incorrect, doesn't follow the correct calculation process.
