A nurse documents that the client has a normal pupillary light reflex. The nurse should recognize that this reflex indicates which of the following?
The eyes converge to focus on the light.
The eye focuses the image in the center of the pupil.
Dilation of both pupils occurs in response to bright light.
Constriction of both pupils occurs in response to bright light.
The Correct Answer is D
A. The eyes converge to focus on the light.
This statement refers to the convergence reflex, where both eyes move medially (towards each other) to maintain single binocular vision when focusing on a near object. It is not related to the pupillary light reflex, which involves changes in pupil size in response to light.
B. The eye focuses the image in the center of the pupil.
This choice does not accurately describe the pupillary light reflex. The pupillary light reflex involves constriction of the pupil in response to light, not focusing an image in the center of the pupil.
C. Dilation of both pupils occurs in response to bright light.
This statement is incorrect. In response to bright light, the pupils should constrict, not dilate. Dilation of pupils in bright light could indicate an abnormal response, such as in cases of certain neurological conditions or drug use.
D. Constriction of both pupils occurs in response to bright light.
This choice is correct. In the pupillary light reflex, both pupils constrict when exposed to bright light. This response is a protective mechanism to prevent excessive light from entering the eyes, ensuring optimal visual acuity.

Correct Answer is D
Explanation
. Presence of breath sounds: While assessing the anterior chest, the nurse should listen for breath sounds over various areas of the lungs. However, this is related to auscultation, not inspection.
B. Diaphragmatic excursion: Diaphragmatic excursion involves assessing the movement of the diaphragm during breathing. This is typically done by percussing the level where dullness changes to resonance during inhalation and exhalation. It is more related to percussion, not inspection.
C. Symmetric chest expansion: Symmetric chest expansion refers to the equal expansion of both sides of the chest during inhalation. The nurse can observe and palpate the chest to assess if it expands symmetrically on both sides. This is a crucial aspect of the inspection of the anterior chest.
D. Shape and configuration of the chest wall: The shape and configuration of the chest wall, including abnormalities or deformities, should be assessed during inspection. This includes observing for any asymmetry, deformities, masses, or scars on the anterior chest.
Correct Answer is D
Explanation
A. Perform the confrontation test:
The confrontation test is a basic visual field screening test. It assesses the peripheral vision by having the patient cover one eye and the examiner covers the opposite eye. The patient and the examiner then bring their fingers into the visual field from the periphery, and the patient indicates when they see the fingers.
B. Ask the patient to read the print on a handheld Jaeger card:
Jaeger cards are used for near vision testing. The patient reads progressively smaller print to assess their near vision acuity.
C. Determine the patient's ability to read newsprint at a distance of 12 to 14 inches:
This method assesses near vision. It is often used informally in clinical settings, where the patient is asked to read a newspaper or similar print at a comfortable reading distance.
D. Use the Snellen chart positioned 20 feet away from the patient:
The Snellen chart is a standardized chart used for visual acuity testing. It is placed 20 feet away from the patient, and the patient is asked to read the letters or symbols on the chart with one eye covered at a time.
