Which of the following are considered normal findings for assessment of the respiratory system? Select all that apply.
Elliptical chest configuration.
Eupnea.
Resonance.
Inspiratory wheezing.
Correct Answer : A,B,C
Choice A rationale
An elliptical chest configuration is considered a normal shape for the thorax. This configuration allows for optimal lung expansion and function. Deviations from this shape, such as a barrel chest, might indicate underlying pulmonary conditions.
Choice B rationale
Eupnea refers to normal, unlabored breathing, which is an expected finding during a respiratory assessment. It indicates that the individual is not experiencing respiratory distress and that their respiratory rate, rhythm, and effort are within normal limits.
Choice C rationale
Resonance is a normal percussion sound heard over healthy lung tissue. It indicates that the underlying lung areas are filled with air, which is a positive sign of healthy lung function.
Choice D rationale
Inspiratory wheezing, a high-pitched whistling sound during breathing, is typically indicative of narrowed or obstructed airways, often associated with conditions such as asthma or chronic obstructive pulmonary disease, and is not considered a normal finding.

Correct Answer is A
Explanation
Choice A rationale
The Angle of Louis, also known as the sternal angle, is located at the level of the 2nd intercostal space. It is a significant landmark in clinical examinations because it is used to locate important areas of the chest, such as the aortic and pulmonic areas, for auscultation.
Choice B rationale
The 3rd intercostal space is not the correct location for the Angle of Louis. The sternal angle is found at the level of the 2nd intercostal space, not the 3rd. Therefore, this option is incorrect.
Choice C rationale
The 2nd rib attaches at the level of the Angle of Louis. The sternal angle is an anatomical landmark where the manubrium and the body of the sternum meet, and it corresponds with the attachment of the 2nd rib.
Choice D rationale
The 4th intercostal space is not the correct location for the Angle of Louis. The sternal angle is located at the 2nd intercostal space, not the 4th. Therefore, this option is incorrect. .
Correct Answer is C
Explanation
Choice A rationale
Rhonchi are low-pitched, coarse sounds typically heard during expiration, associated with secretions in large airways, not high-pitched continuous sounds.
Choice B rationale
Stridor is a high-pitched sound heard during inspiration, typically indicating upper airway obstruction.
Choice C rationale
Wheezes are continuous high-pitched whistling sounds heard during expiration, common in conditions like chronic obstructive pulmonary disease, where airway narrowing is present.
Choice D rationale
Crackles are discontinuous sounds heard during inspiration, usually associated with fluid in the lungs or alveolar opening, not continuous high-pitched sounds. .
