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

A. Faint whistling may indicate wheezing, which is abnormal and typically associated with airway obstruction or asthma. B. Crackling throughout the lung fields may indicate conditions like pneumonia or pulmonary edema. C. Differences in breath sounds between the right and left lung could indicate pathology such as consolidation or a pleural effusion. D. The blowing, hollow sounds heard above the sternum are normal bronchial breath sounds, typically heard over the trachea and large airways.
