To perform the test, a nurse should: 1. Explain the procedure to the patient to reduce anxiety. 2. Dim the room lights to enhance the visibility of pupillary changes. 3. Ask the patient to fixate on a distant object to prevent accommodation. 4. Shine a light from the side into one eye and observe the direct response (constriction of the illuminated pupil). 5. Observe the consensual response (constriction of the opposite pupil). 6. Repeat the procedure for the other eye.
