Which term describes a dilated pupil?

The term that describes a dilated pupil is "mydriatic." Mydriasis refers specifically to the dilation of the pupils, which can occur in various situations, such as in response to low light conditions, certain medications, or neurological conditions. Understanding this term is important in clinical settings, as pupil size and reactivity can provide valuable information about a patient's neurological status or help in diagnosing underlying conditions.

The other terms have distinct meanings; for instance, a sympathetic response typically involves physiological reactions associated with "fight or flight," which can include pupil dilation. However, this option is more about the underlying nerve response rather than the direct description of pupil size. A fixed pupil refers to a pupil that does not respond to light changes or accommodation, indicating potential neurological damage, while miotic refers to a constricted pupil, the opposite of mydriatic. Recognizing these distinctions is crucial for properly interpreting ocular assessments in critical care situations.
