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

Choice A reason: Breath sounds should be symmetrical bilaterally. Louder breath sounds on the right may indicate asymmetry due to pathology such as consolidation, effusion, or obstruction. Choice B reason: Crackles are adventitious sounds typically associated with fluid in the alveoli, seen in conditions like pneumonia, heart failure, or pulmonary fibrosis. They are not considered normal. Choice C reason: Blowing, hollow sounds heard above the sternum are consistent with bronchial breath sounds, which are normal when auscultated over the trachea or upper sternum. Choice D reason: Faint whistling sounds are indicative of wheezing, which is abnormal and often associated with airway narrowing due to asthma, COPD, or bronchospasm.
