Question

The medication order is for 3 mg of a drug. The medication label reads 15 mg / 5 mL. How many mL will the nurse administer to the patient?

Answer 1

You can make a proportion:
\[\frac{3 \ \text{mg}}{x \ \text{mL}}= \frac{15 \ \text{mg}}{5 \ \text{mL}}\]
Now just solve for the amount of mL needed to be administered, x.
