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. Friction rub:
A friction rub is a grating or rubbing sound or sensation heard or felt during auscultation or palpation. It occurs when inflamed pleural or pericardial surfaces rub against each other during breathing or heartbeats, respectively.
B. Tactile fremitus:
Tactile fremitus refers to the palpable vibrations transmitted through the bronchopulmonary tree to the chest wall as the patient speaks. It is assessed by placing hands on the patient's back while the patient speaks certain words. Increased tactile fremitus can occur in conditions with lung consolidation, such as pneumonia.
C. Crepitus:
Crepitus is a crackling or grating sensation felt under the skin or heard when the ends of a broken bone rub against each other. It can also occur when air leaks into subcutaneous tissue, leading to a crackling sensation upon palpation.
D. Adventitious sounds:
Adventitious sounds refer to abnormal lung sounds heard during auscultation. These sounds include crackles (rales), wheezes, rhonchi, and pleural friction rubs. Adventitious sounds can indicate various respiratory conditions, such as pneumonia, bronchitis, or asthma.
