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 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.
Correct Answer is A
Explanation
A. Indicates turbulent blood flow through a valve:
This statement is correct. A heart murmur is an abnormal sound during the heartbeat cycle, often indicating turbulent blood flow through a valve. Murmurs can result from various factors such as valve disorders, structural abnormalities, or other heart conditions.
B. Is an extra sound due to blood entering an inflexible chamber:
This statement is not accurate. Heart murmurs are primarily associated with turbulent blood flow rather than an extra sound related to an inflexible chamber.
C. Means that there is some inflammation around the heart:
This statement is incorrect. Heart murmurs are not specifically related to inflammation around the heart. They are primarily caused by issues with blood flow through the heart valves.
D. Is a high-pitched sound due to a narrow valve:
This statement is a bit oversimplified. While murmurs can sometimes be associated with narrow valves (stenosis), they can also result from various other valve abnormalities or conditions, and not all murmurs are high-pitched. The pitch and characteristics of a murmur can provide clues about its cause, but they are not the sole indicators.
