What is the volume of Epogen that should be administered for a patient prescribed 8000u when the facility stocks it at a concentration of 20,000/ml?

To determine the volume of Epogen to administer, you first need to understand the relationship between the drug's prescribed dosage and its concentration.

The patient is prescribed 8000 units of Epogen, and the facility has a stock concentration of 20,000 units per milliliter. To find out how much volume is needed to deliver the prescribed dosage, you can use the following formula:

Volume (ml) = Prescribed Dose (units) / Concentration (units/ml)

Plugging in the values:

Volume (ml) = 8000 units / 20,000 units/ml

This calculation simplifies to:

Volume (ml) = 0.4 ml

Thus, the correct volume of Epogen to administer is 0.4 ml. This is why the answer indicating 0.4 ml is accurate. It's important to ensure that calculations involving medication dosages are precise to guarantee patient safety and effective treatment.
