A nurse is auscultating the breath sounds of a client who has asthma. When the client exhales, the nurse hears continuous high-pitched squeaking sounds. The nurse should document this as which of the following adventitious breath sounds?

A. Stridor: Stridor is a harsh, high-pitched sound heard primarily during inspiration and is usually caused by upper airway obstruction, such as laryngeal edema or foreign body aspiration. It is not typically associated with asthma exacerbations. B. Wheezes: Wheezes are continuous, high-pitched, musical sounds most often heard during expiration, caused by narrowing of the lower airways due to bronchospasm or inflammation. They are a hallmark finding in clients with asthma. C. Crackles: Crackles are intermittent, non-musical sounds heard during inspiration and are caused by fluid, mucus, or collapsed alveoli popping open. They are more commonly associated with pneumonia, heart failure, or pulmonary fibrosis. D. Rhonchi: Rhonchi are low-pitched, coarse, snoring-like sounds caused by secretions or obstruction in the larger airways. They often clear with coughing and are not the typical finding in asthma.
