ANS: 2
Sounds heard during auscultation over the trachea should be loud, high-pitched and hollow. Soft, low-pitched, and breezy sounds are heard over the lung’s periphery.
Moist, crackling, and bubbling sounds are adventitious sounds known as “crackles” and are caused by sudden reinflation of groups of alveoli and disruptive passage of air. They are most commonly heard in dependent lobes: right and left lung bases. High-pitched and musical sounds are wheezes. Wheezes can be heard over all lung fields.
