Final answer:
To administer a dose of 220,000 units of penicillin G procaine when it is supplied at 600,000 units/ml, divide the desired dose by the concentration of the drug to determine the volume to be administered in milliliters.
Step-by-step explanation:
The calculation of medication dosage is a critical component in the medical field to ensure patient safety and effective treatment. The question requires us to determine how many milliliters (ml) of penicillin G procaine, supplied at 600,000 units per ml, should be administered to deliver a dose of 220,000 units.
To calculate the volume of the solution needed for the desired dosage, we use the formula:
Volume of drug required (ml) = Desired Dose (units) / Concentration of drug (units/ml)
Plugging in the values from the question, we get:
Volume of drug required (ml) = 220,000 units / 600,000 units/ml
This calculation will result in a value that signifies the amount of solution needed to administer the prescribed dose.
