In medication terminology, what does AS refer to?

In medication terminology, "AS" stands for "left ear." This abbreviation is derived from the Latin "auris sinistra," which specifically denotes the left ear when documenting or prescribing medication related to auditory treatments or conditions. When healthcare providers use such abbreviations, it helps ensure clear communication about where the treatment should be applied or administered, reducing the risk of errors in medication administration.

The other options represent different anatomical sites or methods but do not correspond to the abbreviation "AS." For instance, "both ears" would be denoted by "AU" (auris utraque), while "right eye" is represented by "OD" (oculus dexter), and "sublingual administration" does not have a specific abbreviation but describes the method of placing a drug under the tongue. Understanding these abbreviations is crucial in medication management to ensure patient safety.
