The physician orders guaifenesin, 3 teaspoons P.O. as needed. What is the conversion of 1 teaspoon to the metric system?

Explanation

•One teaspoon is equivalent to 5 mL.

•Incorrect: 5 Milligrams (mg) is a unit of mass, not volume.

•Incorrect: 1 mL is equal to 1 cc. Never use cc. The standard is mL.

•Incorrect: It is not 15 mL because the stem of the question asked for the conversion of 1 teaspoon.
