When assessing the pupillary light reflex or PERRL (pupils, round, reactive to light), the nurse should use which technique?
Shine a light across the pupil from the side, and observe for direct and consensual pupillary constriction.
Ask the patient to follow the penlight in eight directions, and observe for bilateral pupil constriction.
Shine a penlight from directly in front of the patient, and inspect for pupillary constriction.
Ask the patient to focus on a distant object. Then ask the patient to follow the penlight to approximately 7 cm from the nose.
The Correct Answer is A
A. Shine a light across the pupil from the side: To assess the pupillary light reflex, the nurse should shine a light across the pupil from the side and observe for both direct and consensual constriction (the constriction of both pupils when one is exposed to light).
B. Follow the penlight: This tests for accommodation (focusing on near objects) rather than the pupillary light reflex.
C. Shine a penlight directly in front: This method doesn’t assess both direct and consensual constriction properly.
D. Focus on a distant object: This assesses accommodation, not the pupillary light reflex.

Determine areas of pain to avoid causing discomfort during palpation and percussion. Lightly palpate to assess for tenderness or masses. Percuss last to evaluate organ size and detect abnormal fluid or gas.
