The nurse is caring for a patient who has a prescription for Heparin 1000 units/hr IV continuous infusion. The pharmacist delivers Heparin 25,000 units in 500 mL. The nurse sets the pump at how many milliliters per hour to deliver 1000 units per hour?

To determine how many milliliters per hour the nurse should set the pump to deliver 1000 units of Heparin per hour, we can set up a proportion using the given information:

- The Heparin concentration is **25,000 units** in **500 mL**.
- The target dosage is **1000 units per hour**.

### Step-by-step solution:

1. **Calculate the concentration of Heparin per milliliter:**
   \[
   \text{Concentration} = \frac{25,000 \, \text{units}}{500 \, \text{mL}} = 50 \, \text{units/mL}
   \]

2. **Set up a proportion to find the milliliters per hour:**
   \[
   \frac{1000 \, \text{units}}{x \, \text{mL}} = 50 \, \text{units/mL}
   \]
   Where \(x\) is the number of milliliters per hour.

3. **Solve for \(x\):**
   \[
   x = \frac{1000 \, \text{units}}{50 \, \text{units/mL}} = 20 \, \text{mL/hr}
   \]

### Conclusion:
The nurse should set the pump to **20 mL per hour** to deliver 1000 units of Heparin per hour.

Would you like a detailed breakdown of any step or further clarification?

Here are 5 related questions for practice:
1. If the doctor increases the dosage to 1500 units/hr, what would be the new pump setting?
2. How many hours will it take to deliver the entire 500 mL bag at a rate of 20 mL/hr?
3. If the concentration was 30,000 units in 500 mL, how would the rate change for 1000 units/hr?
4. How would you adjust the pump if the dosage was reduced to 800 units/hr?
5. What is the total amount of Heparin delivered after 5 hours at 20 mL/hr?

**Tip:** When using a proportion, always ensure units are consistent to avoid confusion.
