What unit is standard for measuring liquid prescriptions?

• A. Milliliters (mL).
• B. Teaspoons
• C. Ounces
• D. Liters

Answer: (A)

The standard unit for measuring liquid medications in prescriptions is milliliters. Using milliliters fits the metric system, providing precise, uniform volumes that align with labeling and dosing calculations. Teaspoons are a household measure and vary in size, which can lead to dosing errors. Ounces are not standard for prescription dosing and can cause confusion with weight units, while liters are used for much larger volumes and not practical for typical single-dose liquids. So milliliters are used to ensure accuracy and consistency in dispensing liquid medications.
