Final answer:
To administer 4g of a medication that is available in a concentration of 0.2g per 5cc, you should give 100cc of the medication.
Step-by-step explanation:
The pediatrician has ordered 4g of medication, and the medication is available at a concentration of 0.2g per 5cc. To determine how many cubic centimeters (cc) you should administer, you need to set up a proportion based on the concentration of the medication. Since 0.2g is equivalent to 5cc, you can calculate the amount of cc for 4g as follows:
(0.2g / 5cc) = (4g / x cc)
Solve for x:
x = (4g * 5cc) / 0.2g
x = 20g / 0.2g
x = 100cc
Therefore, you should administer 100cc of the medication to deliver a dose of 4g.
