Which statement is correctly true about teaspoon and milliliter conversions?

• A. 1 teaspoon equals 5 mL
• B. 1 teaspoon equals 15 mL
• C. 1 tablespoon equals 5 mL
• D. 1 cup equals 480 mL

Answer: (A)

In medication dosing, small-volume measurements use a simple, standard relationship: 1 teaspoon is equal to 5 milliliters. This makes it easy to convert orders written in teaspoons into metric measurements you can measure accurately with a syringe or cup. So a 1 teaspoon dose is 5 mL, which is a common reference used in nursing and home care settings. Understanding the rest helps prevent errors. A tablespoon is larger than a teaspoon and equals 15 mL (three teaspoons), not 5 mL. A cup is much larger still in US practice—one cup is 240 mL, so 480 mL would be two cups. Keeping these distinctions in mind helps ensure doses are prepared correctly and safely.
