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 ["B","C","D","E"]
Explanation
A. Age: While age itself is not modifiable, it is included in the list because aging increases the risk of developing cardiovascular disease. However, individuals cannot change their age, so it is not a modifiable risk factor.
B. Smoking: Smoking is a significant risk factor for cardiovascular disease. It damages the heart and blood vessels and can lead to atherosclerosis (narrowing and hardening of the arteries), which can result in heart attacks and strokes.
C. Hypertension: High blood pressure is a leading cause of cardiovascular disease. It can damage the arteries over time, making them more susceptible to atherosclerosis.
D. Diabetes: Diabetes, especially if poorly controlled, increases the risk of cardiovascular disease. High blood sugar levels can damage the blood vessels and the heart.
E. High cholesterol: Elevated levels of cholesterol, especially low-density lipoprotein (LDL) cholesterol, can lead to the buildup of plaque in the arteries, increasing the risk of atherosclerosis and cardiovascular events.
