A 35 mg dose of corticosteroid is prescribed IM. How many milliliters should be administered if available as 250 mg/10 mL?

To determine how many milliliters of the corticosteroid should be administered, it's important to first establish the concentration of the solution available. The medication is available as 250 mg in 10 mL, which means there are 25 mg of the corticosteroid in every 1 mL (because 250 mg divided by 10 mL equals 25 mg/mL).

Next, since the prescribed dose is 35 mg, you can calculate the required volume of the solution needed to achieve this dose by using the concentration. To find out how many milliliters are needed to equal 35 mg, divide the desired dose by the concentration:

35 mg ÷ 25 mg/mL = 1.4 mL.

Thus, the correct amount of solution to administer is 1.4 mL, which aligns with the response given. This calculation is essential in pharmacology to ensure accurate dosing for safe and effective patient care.
