A 46-year-old patient presents to the clinic complaining of shortness of breath. The medical assistant performs a physical assessment. Which of the following findings would be considered a normal characteristic of healthy adult lung sounds?
Stridor heard over the anterior neck
Vesicular breath sounds throughout the lung fields
Vesicular breath sounds are low-pitched, soft sounds heard over most of the lungs' surface and are considered normal. Bronchial breath sounds, heard over the trachea, are higher-pitched and louder but would not be expected over the peripheral lung fields. Stridor is a high-pitched wheeze that indicates obstruction in the upper respiratory tract, which is abnormal. Diminished breath sounds may suggest restrictive lung disease or pleural effusion, which are also abnormal findings.
