Which assessment finding, obtained during chest auscultation, should the nurse consider a normal finding?

A. Right breath sounds louder than left: While there might be slight variations, breath sounds should generally be equal in intensity on both sides of the chest. Breath sounds should be relatively equal bilaterally. Asymmetry in sound intensity can indicate consolidation, obstruction, or a pneumothorax. B. Slight crackling throughout lung fields: Crackles (rales) are abnormal sounds typically associated with fluid in the alveoli, as seen in conditions like heart failure, pneumonia, or pulmonary fibrosis. They are not a normal finding in healthy lung tissue. C. Faint whistling over both lung bases: Whistling or high-pitched sounds suggest wheezing, often caused by narrowed airways due to asthma, bronchitis, or other obstructive airway diseases. This is considered an abnormal finding. D. Blowing, hollow sounds above sternum: These describe bronchial breath sounds, which are normally heard over the trachea and manubrium (above the sternum). They have a blowing, hollow quality and are considered a normal finding in that location.
