How is milligram abbreviated in medication dosage?

In the context of medication dosage, the abbreviation for milligram is "mg." This standard abbreviation is widely recognized in the medical field for accurately communicating the amount of a substance in medications. Using this abbreviation helps ensure clarity and precision in prescribing, administering, and understanding medication dosages.

The other choices represent different measurements that are not related to milligrams. For example, "ml" stands for milliliter, which measures volume rather than mass. "liq." typically indicates a liquid form of medication, and "Sol" is an abbreviation for solution. These terms are important in healthcare but refer to different aspects of medication rather than the unit of weight used in milligrams.
