Question

the healthcare provider orders heparin, 400 units/hour via an infusion pump. the pharmacy supplies a solution of heparin in 40,000 units in 1000 ml of d5w. the nurse would set the infusion pump to run at how many milliliters per hour? 40 ml/hour 20 ml/hour 10 ml/hour 5 ml/hour

Explanation:

Step1: Find the concentration of heparin

The pharmacy supplies 40,000 units in 1000 mL. So the concentration is $\frac{40000 \text{ units}}{1000 \text{ mL}} = 40 \text{ units/mL}$.

Step2: Calculate the infusion rate

We need to deliver 400 units per hour. Using the formula: Rate (mL/hour) = $\frac{\text{Dose (units/hour)}}{\text{Concentration (units/mL)}}$.
Substitute the values: Rate = $\frac{400 \text{ units/hour}}{40 \text{ units/mL}} = 10 \text{ mL/hour}$.

Answer:

10 mL/hour
