Which of the following are considered normal findings for assessment of the respiratory system? Select all that apply.

Choice A rationaleAn 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 rationaleEupnea 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 rationaleResonance 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 rationaleInspiratory 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.
