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 A
Explanation
A. Continue with the assessment, looking for any other abnormal findings: This is the correct response. Tonsils in adults can have various appearances, and a granular appearance with deep crypts is within the range of normal. It's essential for the nurse to continue the assessment and observe for other signs or symptoms that might indicate an issue.
B. Refer the patient to a throat specialist: Referring the patient based solely on the appearance of the tonsils, especially if it's a normal variant, might be unnecessary and could cause undue concern for the patient. It's important to assess the patient comprehensively before considering a specialist referral.
C. No response is needed; this appearance is normal for the tonsils: This is the correct explanation. In adults, tonsils often appear granular with deep crypts, which is considered a normal variation. No further action is required regarding the tonsils.
D. Obtain a throat culture on the patient for possible streptococcal (strep) infection: Based on the description provided (involution, granular appearance, and deep crypts), there's no specific indication of a streptococcal infection. Conducting a throat culture should be based on the presence of specific symptoms and signs indicative of a streptococcal infection, such as sore throat, fever, and swollen tonsils with white patches, rather than just the appearance of the tonsils.
Correct Answer is D
Explanation
A. Percussion of the posterior chest: Percussion helps assess the underlying structures of the chest but does not directly confirm symmetric chest expansion.
B. Inspection of the shape and configuration of the chest wall: Inspection is a crucial part of assessing chest symmetry. Any deformities, asymmetry, or abnormalities in the shape and configuration of the chest wall can be visually identified.
C. Placing the palmar surface of the fingers of one hand against the chest and having the client repeat "ninety-nine": This technique, known as tactile fremitus, involves feeling for vibrations or tremors while the client repeats a phrase. While it can provide information about underlying lung conditions, it's not primarily used to confirm symmetric chest expansion.
D. Placing hands sideways on the posterolateral chest wall with thumbs pointing together at the level of T9 or T10: This technique, known as chest expansion measurement, is used to assess symmetric chest expansion. Placing hands in this manner allows the nurse to feel for bilateral chest expansion during inspiration, ensuring that both sides of the chest expand symmetrically.
