Which liquid measurement unit corresponds to 30 mL?

The correct answer, which is 1 oz, corresponds to 30 mL because of the standard conversion between fluid ounces and milliliters. In the United States, 1 fluid ounce is equivalent to approximately 29.57 mL, which rounds to 30 mL for practical purposes in a pharmacy setting. This conversion is essential for accurately administering medication dosages and ensuring that patients receive the correct amount of liquid medication.

Understanding these conversions is crucial in pharmacy practice, as they often come into play when calculating dosages or converting prescriptions. Fluids are frequently measured in either metric or imperial units, and being adept at navigating these differences is vital for patient safety and effective medication administration.
