The nurse is testing a client's visual accommodation. Which of the following should the nurse recognize as an assessment finding from visual accommodation?
The pupils constrict when the examiner's index finger slowly moves toward the client's nose.
The client involuntary blinks in the presence of bright light directed over the pupils during the eye exam.
The client's peripheral vision becomes sharper when the examiner shines a light over the pupils.
The pupils dilate when the examiner's index finger slowly moves toward the client's nose.
The Correct Answer is A
A. The pupils constrict when the examiner's index finger slowly moves toward the client's nose.
This statement is correct. Visual accommodation is the process by which the eye's lens changes shape to focus on objects at varying distances. When an object moves closer to the eyes, the pupils constrict to adjust and focus on the near object, preventing double vision.
B. The client involuntarily blinks in the presence of bright light directed over the pupils during the eye exam.
This statement describes the pupillary light reflex, not visual accommodation. The pupillary light reflex is the response of the pupils to light exposure.
C. The client's peripheral vision becomes sharper when the examiner shines a light over the pupils.
This statement is not accurate. Peripheral vision sharpness is not related to visual accommodation. Visual accommodation mainly involves adjusting focus for objects at varying distances.
D. The pupils dilate when the examiner's index finger slowly moves toward the client's nose.
This statement is incorrect. Pupils should constrict, not dilate, when focusing on a near object (as in visual accommodation). Dilation occurs in low-light conditions or in response to sympathetic stimulation.

Correct Answer is C
Explanation
A. Bronchovesicular breath sounds and normal in that location:
Bronchovesicular breath sounds are medium-pitched sounds heard over the major bronchi and are usually equal on inspiration and expiration. They are typically heard in the 1st and 2nd intercostal spaces anteriorly and between the scapulae posteriorly. While they might be normal in certain locations, hearing them over peripheral lung fields might indicate an abnormality.
B. Normally auscultated over the trachea:
This statement doesn't specify a particular type of breath sound. Tracheal breath sounds are harsh and relatively high-pitched, heard directly over the trachea. They are normal over the trachea but are not normally heard in the lung periphery.
C. Vesicular breath sounds and normal in that location:
Vesicular breath sounds are low-pitched, soft sounds heard over most of the lungs during inspiration. They are longer on inspiration than expiration and are considered normal breath sounds heard in the peripheral lung fields. Hearing vesicular sounds in the posterior lower lobes is typical and indicates normal lung function.
D. Bronchial breath sounds and normal in that location:
Bronchial breath sounds are high-pitched and loud, heard primarily over the trachea and larynx. If heard in the peripheral lung fields, especially in the lower lobes, it can suggest an abnormality such as consolidation or compression of lung tissue.
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.
