What does AD stand for in medical terminology?

In medical terminology, AD stands for Auris dextra, which translates to "right ear" in Latin. This abbreviation is commonly used in clinical settings to specify which ear is being referenced, particularly when documenting patient information such as hearing assessments or administration of medications.

Understanding these abbreviations is essential in ensuring clear communication and accurate documentation in healthcare. Each term in the other options refers to different anatomical structures or sides: Auris sinister means "left ear," Oculus dextra refers to "right eye," and Oculus sinister stands for "left eye," but only Auris dextra specifically indicates the right ear, thereby making it the correct answer in this context.
