What is the correct dosage in mL for a physician's order of Solu-Medrol 37.5 mg when the available concentration is 125 mg/2 mL?

To determine the correct dosage in mL for the physician's order of Solu-Medrol 37.5 mg with a concentration of 125 mg/2 mL, we need to calculate how many mL are required to achieve the desired dose.

First, we start with the available concentration:

• The concentration of Solu-Medrol is 125 mg in 2 mL.

This means that there are:

• 125 mg / 2 mL = 62.5 mg/mL.

Now, to find out how many mL are needed for 37.5 mg, we set up the following proportion:

• If 62.5 mg is in 1 mL, we can arrange this as:

(Amount in mL) = (Desired dose in mg) / (Concentration in mg/mL).

Substituting in the values:

• Amount in mL = 37.5 mg / 62.5 mg/mL = 0.6 mL.

Therefore, the required dosage to administer 37.5 mg of Solu-Medrol is 0.6 mL.
