Which unit of measurement is commonly used when measuring liquid medications?

The correct answer is milliliters, as this is the standard unit of measurement used for liquid medications. Milliliters provide a precise and manageable way to quantify the volume of liquid. This is especially important in healthcare, where accurate dosing is crucial for the safety and effectiveness of pharmacological treatments. Liquid medications are often administered in small volumes, so using milliliters allows for easy measurement and administration by healthcare professionals.

Other units like grams are typically used for measuring solid substances, while pills are simply the form in which some medications are delivered—not a measurement unit. Units can indicate things like insulin dosages but are not specific for measuring volumes of liquid medications. Therefore, milliliters are the appropriate choice for measuring liquid medications.
