Assistive Medication Administration Personnel (AMAP) Practice Exam

In ophthalmic prescriptions, the abbreviation "OU" stands for "oculus uterque," which is a Latin term meaning "both eyes." This designation is commonly used to indicate that a particular medication or treatment should be applied to both eyes, ensuring a uniform approach to addressing optical conditions affecting both sides. This is essential in scenarios where an eye condition may not be limited to one eye or when a systemic treatment is required for overall eye health.

The other options do not accurately reflect the meaning of "OU" in this context. For instance, "Once used" would not align with typical prescription terminologies, as it suggests a one-time dosage rather than indicating application to two separate anatomical areas. "Ordered uniquely" fails to capture the dual aspect conveyed by the abbreviation, and "Open universally" is unrelated to eye care, lacking any medical specificity. Understanding these nuances is crucial for correct medication administration and patient care.
