During a respiratory assessment, which characteristic of breath sounds would be considered abnormal?

Wheezing is indeed considered an abnormal characteristic of breath sounds during a respiratory assessment. It is typically described as a high-pitched whistling or squeaking sound that occurs when air flows through narrowed airways. This narrowing can be a result of conditions like asthma, bronchitis, or other airway obstructions. In a healthy respiratory system, breath sounds should be clear and unimpeded. The presence of wheezing indicates some form of respiratory compromise or pathology, thus making it an abnormal finding during the assessment.

On the other hand, bronchial breath sounds can be normal over specific areas in the lungs, such as the trachea or major bronchi, but their presence in the lower lobes can indicate consolidation or other abnormalities. Vesicular breath sounds, characterized by a soft and low-pitched quality, are normal when heard throughout the lung fields, whereas clear and loud breath sounds can also occur in healthy individuals. However, if bronchial sounds are heard in inappropriate areas or if there are other obstructive sounds such as wheezing, those may indicate underlying issues that require further evaluation.
