A nurse sees documentation in the client's record indicating that the health care provider has noted the presence of adventitious breath sounds. The nurse knows that these types of sounds have which aspect?

Adventitious breath sounds are abnormal sounds that are not normally heard in the lungs. These sounds are added sounds superimposed on the breath sounds. They are caused by air colliding with secretions in the tracheobronchial passageways or when previously deflated airways pop open. Hollow sounds heard over the trachea and larynx are normal bronchial (tracheal) breath sounds, not adventitious. Rustling sounds heard over the peripheral lung fields are normal vesicular breath sounds, not adventitious. Therefore, the correct answer is that adventitious breath sounds are abnormal sounds that should not be heard in the lungs.
