The nurse is assessing the heart sounds of a client. The nurse understands that to listen to the pulmonic valve, the stethoscope should be placed where?

A. The eyes converge to focus on the light.

This statement refers to the convergence reflex, where both eyes move medially (towards each other) to maintain single binocular vision when focusing on a near object. It is not related to the pupillary light reflex, which involves changes in pupil size in response to light.

B. The eye focuses the image in the center of the pupil.

This choice does not accurately describe the pupillary light reflex. The pupillary light reflex involves constriction of the pupil in response to light, not focusing an image in the center of the pupil.

C. Dilation of both pupils occurs in response to bright light.

This statement is incorrect. In response to bright light, the pupils should constrict, not dilate. Dilation of pupils in bright light could indicate an abnormal response, such as in cases of certain neurological conditions or drug use.

D. Constriction of both pupils occurs in response to bright light.

This choice is correct. In the pupillary light reflex, both pupils constrict when exposed to bright light. This response is a protective mechanism to prevent excessive light from entering the eyes, ensuring optimal visual acuity.

A. Wheezing: Wheezing is a continuous, high-pitched whistling sound usually heard during expiration. It is often associated with narrowed airways, such as in asthma or chronic obstructive pulmonary disease (COPD). Wheezing occurs due to the turbulent airflow through narrowed bronchi or bronchioles and is not typically associated with pleuritis.

B. Friction rub: Pleuritis, or inflammation of the pleura, can cause a friction rub. This sound occurs when the inflamed pleural layers rub against each other during breathing. It's a grating or rubbing sound heard on auscultation and is a hallmark sign of pleuritis.

C. Stridor: Stridor is a high-pitched, harsh sound heard during inspiration and sometimes expiration. It is often a sign of upper airway obstruction, such as in croup or anaphylaxis. Stridor results from turbulent airflow through a partially obstructed or narrowed larynx or trachea.

D. Crackles: Crackles, also known as rales, are brief, discontinuous, popping sounds heard on inspiration. They can be fine or coarse and are often associated with conditions that cause fluid or secretions in the alveoli or small airways, such as pneumonia or heart failure. Crackles are not typically associated with pleuritis.
