Convert 15 mL into teaspoons.

To convert milliliters (mL) to teaspoons, it's important to know that 1 teaspoon is equivalent to approximately 5 mL. Therefore, to find out how many teaspoons are in 15 mL, you can use the conversion factor:

15 mL ÷ 5 mL/teaspoon = 3 teaspoons.

This calculation shows that 15 mL is equal to 3 teaspoons, confirming that the correct answer reflects an accurate application of the conversion ratio. Understanding these basic conversions is crucial in nursing practice, as precise dosing is vital for patient safety and efficacy of medication administration.
