Which abbreviation indicates the right ear?

The abbreviation that indicates the right ear is "AD," which stands for "auris dextra" in Latin. This terminology is commonly used in medical prescriptions and documentation to specify which ear is being referred to, particularly in the context of administering medications or treatments.

Understanding such abbreviations is crucial for pharmacy technicians, as accurate communication regarding medication administration routes is vital for patient safety. In situations involving ear medications or diagnostics, using the correct abbreviation ensures that healthcare providers and patients are on the same page regarding treatment specifics.

The other abbreviations serve different purposes: "AS" stands for "auris sinistra," meaning the left ear; "AQ" generally refers to water and is not related to ear designations; "AU" means both ears. Knowing these distinctions helps prevent medication errors and enhances the overall efficiency of patient care.
