Question

The physician orders 160 mg/mL of Depo-Medrol. You have 40mg/mL on hand. How many milliliters will you give?

Answer 1

To administer a 160 mg dose of Depo-Medrol using a 40 mg/mL solution, you would need to give 4 mL of the solution.

Step-by-step explanation:

The physician orders 160 mg of Depo-Medrol and the concentration available on hand is 40 mg/mL. To find the volume (mL) required to administer a 160 mg dose using a 40 mg/mL solution, you use the following calculation:

1. First, write down the desired dose: 160 mg.
2. Next, identify the concentration of the solution available: 40 mg/mL.
3. To calculate the volume needed for the desired dose, divide the desired dose by the concentration of the solution:
   V = Dose / Concentration
4. So, we have V = 160 mg / 40 mg/mL
5. The resulting calculation is V = 4 mL. Therefore, you will administer 4 mL of the 40 mg/mL Depo-Medrol solution to deliver a 160 mg dose.
