A nurse is performing a respiratory system physical examination. To assess the resonance of voice sounds heard during auscultation of the lungs, the nurse instructs the patient to say "ee," and if the sound is heard as "ay," this is known as:

Choice A reason:
Peripheral vision is the ability to see objects and movement outside of the direct line of vision. This type of vision is assessed using different methods, such as confrontation visual field testing, where the examiner moves objects into the patient's side vision from different angles. Standing 20 feet away from a chart would not be the appropriate method to assess peripheral vision.
Choice B reason:
The assessment of external eye structures involves examining the physical appearance and condition of the eyelids, sclera, conjunctiva, and surrounding areas. This is typically done at a close range and does not require the patient to stand at a distance from a chart. The nurse would inspect these structures directly, often with the aid of a penlight for better visibility.

Choice C reason:
Distant vision is the ability to see objects far away, and it is what the nurse is preparing to assess when the client is asked to stand 20 feet from a chart. This distance is standard for the Snellen eye chart, which is used to measure visual acuity. The chart has rows of letters that decrease in size, and the patient is asked to read the smallest line of letters they can see clearly. The Snellen chart is the most common method used by eye doctors to measure visual acuity.
Choice D reason:
Near vision is the ability to see objects that are close to the eyes clearly. It is assessed using different charts, such as the Jaeger eye chart, which contains blocks of text in various type sizes. The patient is asked to read the text at a close range, typically around 14 inches, not 20 feet. Therefore, standing 20 feet away from a chart would not be the method to assess near vision.

Choice A Reason:
Tracheal sounds are harsh, high-pitched breath sounds typically heard over the trachea in the neck. They are not expected to be heard over the peripheral lung fields of a young adult during a routine lung auscultation.

Choice B Reason:
Vesicular breath sounds are the normal sounds heard over most of the lung fields. They are characterized by a soft, low-pitched, rustling sound during inhalation and are softer during exhalation. These sounds are created by air moving through the smaller airways such as the bronchioles and alveoli.

Choice C Reason:
Bronchovesicular sounds are heard over the major bronchi and are characterized by a moderate pitch and intensity. They are typically heard between the first and second intercostal spaces at the sternal border anteriorly and between the scapulae posteriorly, not over most of the lung fields.

Choice D Reason:
Bronchial breath sounds are high-pitched and louder than vesicular sounds, with a hollow quality, and are normally heard over the manubrium. If heard over the peripheral lung fields, they may indicate lung consolidation or other abnormalities.
