I see that the image contains several medical dosage calculations involving infusion rates for medications such as Albumin, Insulin, and Heparin. Let's break them down one by one:

### 1. **Albumin Infusion Rate**:
   - **Order**: 25% Albumin, 50 mL to run over 15 minutes, every 6 hours.
   - **Goal**: Determine the rate (mL per hour) that the nurse must set on the pump.

   **Solution**:
   - Time is given as 15 minutes, so convert this to hours: \( 15 \, \text{minutes} = 0.25 \, \text{hours} \).
   - To find the rate:
     \[
     \text{Rate} = \frac{\text{Volume}}{\text{Time}} = \frac{50 \, \text{mL}}{0.25 \, \text{hours}} = 200 \, \text{mL/hour}.
     \]
   - **Answer**: \( X = 200 \, \text{mL per hour} \).

### 2. **Insulin Infusion Rate**:
   - **Order**: 100 units of insulin in 50 mL of 0.9% NS, running at 4 units per hour.
   - **Goal**: Determine the rate (mL per hour) to set on the pump.

   **Solution**:
   - Set up a proportion using units and volume:
     \[
     \frac{100 \, \text{units}}{50 \, \text{mL}} = \frac{4 \, \text{units}}{X \, \text{mL}}.
     \]
   - Cross-multiply:
     \[
     100X = 200.
     \]
   - Solve for \( X \):
     \[
     X = \frac{200}{100} = 2 \, \text{mL per hour}.
     \]
   - **Answer**: \( X = 2 \, \text{mL per hour} \).

### 3. **Heparin Infusion Rate**:
   - **Order**: 25,000 units in 500 mL, current rate on the pump is 30 mL per hour.
   - **Goal**: Determine the dose of Heparin the patient is receiving every hour.

   **Solution**:
   - Set up a proportion using units and volume:
     \[
     \frac{25,000 \, \text{units}}{500 \, \text{mL}} = \frac{Y \, \text{units}}{30 \, \text{mL}}.
     \]
   - Cross-multiply:
     \[
     500Y = 750,000.
     \]
   - Solve for \( Y \):
     \[
     Y = \frac{750,000}{500} = 1,500 \, \text{units per hour}.
     \]
   - **Answer**: The patient is receiving **1,500 units of Heparin per hour**.

Would you like further explanation on any of these calculations, or do you have other related questions?

### Follow-up Questions:
1. How would you adjust the Heparin dosage if the rate on the pump was changed to 40 mL/hour?
2. If the insulin infusion was reduced to 2 units/hour, what would the new pump rate be?
3. What is the significance of the concentration (e.g., 25% Albumin) when calculating infusion rates?
4. How do you calculate total dosage administered over several hours for any of these infusions?
5. What factors might affect the accuracy of these infusion rate calculations in a real medical setting?

### Tip:
Always double-check unit conversions (minutes to hours, mL to L, etc.) in infusion rate calculations to avoid critical errors.

Order for Albumin 25% 50 mL to run over 15 minutes every 6 hours. What rate must the nurse set on the pump? Insulin infusion order: 100 units in 50 mL of 0.9% NS to run at 4 units per hour. What rate must be set on the pump? Nurse is caring for a patient on a Heparin infusion: 25,000 units in 500 mL. The current rate on the pump is 30 mL per hour. What is the dose of Heparin that the patient is receiving every hour?
