Final answer:
To provide the patient with 120 milligrams of medication, set up a proportion using the given concentration, calculate the milligrams per milliliter, and find out that the patient should be given 2 milliliters of the medication.
Step-by-step explanation:
The student's question involves calculating the appropriate dosage of medication based on given concentrations, which is a mathematics problem related to ratio and proportion. To find the number of milliliters needed to provide the patient with 120 milligrams of medication, we can set up a proportion:
Since 0.5 milliliters contains 30 milligrams of medication, we can determine how many milliliters would contain 120 milligrams.
First, we calculate the amount of milligrams per milliliter:
30 mg / 0.5 mL = 60 mg/mL
Now we need to find out how many milliliters would be needed to get 120 milligrams:
120 mg / (60 mg/mL) = 2 milliliters
So, the patient should be administered 2 milliliters of the medication to receive a dose of 120 milligrams.
