What does the abbreviation OU stand for in medical terms?

Left ear
Right ear
Both eyes
Both ears

The correct answer is: Both eyes

The abbreviation OU stands for "oculus uterque," which is Latin for "both eyes." This term is commonly used in medical settings, particularly in ophthalmology, to indicate that a treatment or prescription applies to both eyes. Understanding this abbreviation is crucial for Patient Care Technicians as they may need to communicate effectively about eye examinations, treatments, or prescriptions that involve both eyes of a patient. In contrast, other choices refer to specific anatomical references rather than a dual action affecting both sides. For example, abbreviations indicating left or right ear would specifically refer to their respective sides, thus not encompassing the concept of 'both.' This clarity ensures accurate communication and understanding in patient care settings.
