How many ml/hour should a nurse administer for Heparin Sodium 25,000 Units in 500 ml IV at 1,000 unit/hour after a decrease of 100 units/hour?

To determine the correct infusion rate in mL/hour for Heparin Sodium, we start by considering the total concentration of the solution and the required dosage.

You have a total of 25,000 Units of Heparin in 500 mL of IV solution. First, we need to calculate the concentration of Units per mL:

[

\text{Concentration} = \frac{25,000 \text{ Units}}{500 \text{ mL}} = 50 \text{ Units/mL}

]

Next, the prescribed infusion rate is 1,000 Units/hour. To find the corresponding flow rate in mL/hour, you can use the concentration of the solution.

To calculate the required mL/hour for a dosage of 1,000 Units/hour:

[

\text{mL/hour} = \frac{\text{Desired dose (Units/hour)}}{\text{Concentration (Units/mL)}}

]

Plugging in the numbers:

[

\text{mL/hour} = \frac{1,000 \text{ Units/hour}}{50 \text{ Units/mL}} = 20 \text{ mL/hour}

]

Now taking into account the decrease of
