Final answer:
To determine the mL of medication to administer, divide the grams needed by the concentration in grams per mL.
Step-by-step explanation:
To determine the number of milliliters (mL) that need to be administered given a medication dosage in grams (g) and the concentration of the medication available, we can use the following formula:
mL = (grams needed / concentration in grams per mL)
The physician has ordered 60 grams of medication and the concentration on hand is 15 grams per 30 mL. To solve for the required volume of medication in milliliters (mL), we set up the following equation:
15 grams : 30 mL = 60 grams : x mL
Now we cross-multiply to solve for x.
(15 grams) * (x mL) = (60 grams) * (30 mL)
x = (60 grams * 30 mL) / 15 grams
x = 1800 mL / 15
x = 120 mL
Therefore, you will need to administer 120 mL of the medication.
