The nurse is listening to the heart sounds of a client. The nurse recognizes that the S2:

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.

A. Simultaneously palpating both arteries to compare amplitude: While comparing amplitudes is important, using the diaphragm of the stethoscope to listen for bruits (abnormal whooshing sounds indicating turbulent blood flow) is a more specific and accurate method for assessing the carotid arteries for potential vascular issues.

B. Listening with the diaphragm of the stethoscope to assess for bruits: This technique allows the nurse to detect abnormal sounds (bruits) that could indicate partial blockages or stenosis in the carotid arteries, suggesting a risk of stroke or transient ischemic attack.

C. Instructing the patient to take slow deep breaths during auscultation: Deep breaths are more relevant during lung auscultation. Carotid artery assessment focuses on detecting abnormal sounds and assessing blood flow rather than respiratory patterns.

D. Palpating the artery at the base of the neck: Palpation alone does not provide enough information about potential blockages or abnormalities in the carotid arteries. Listening with a stethoscope allows for a more detailed assessment of blood flow and the presence of bruits.f the nurse hears a bruit during auscultation, they shouldnotpalpate the carotid artery. A bruit suggests partial obstruction (carotid stenosis), and compressing the artery further could worsen blood flow.
