Practice Question
A nurse documents that a client has a normal pupillary light reflex. The nurse should recognize that this reflex indicates which of the following?
Answer Choices:
Correct Answer:
Constriction of both pupils occurs in response to bright light
Rationale:
👁️A normal pupillary light reflex produces bilateral constriction (direct and consensual) to bright light, demonstrating intact CN II (afferent) and CN III (efferent) pathways.
👁️Light to one eye causes that eye’s pupil to constrict (direct response) and the opposite eye’s pupil to constrict (consensual response).
👁️This reflex confirms parasympathetic activation of the sphincter pupillae and midbrain integrity.
👁️Equal, round, and reactive pupils are documented as PERRL, a key neuro assessment datum.
👁️Abnormalities (e.g., anisocoria, afferent pupillary defect) prompt neurologic/ophthalmic evaluation.
