A nurse is auscultating the lungs of a client who has pleurisy. Which of the following adventitious breath sounds should the nurse expect to hear?

The correct answer is B: Loud, grating sounds. In pleurisy, the inflamed pleural surfaces rub against each other, creating a loud, grating sound known as pleural friction rub. This sound is heard during both inspiration and expiration and is typically localized to the area of inflammation. Popping sounds (A) are associated with atelectasis or airway collapse. Snoring sounds (C) are caused by upper airway obstruction, not pleurisy. Squeaky, musical sounds (D) are characteristic of wheezing, typically seen in conditions like asthma or COPD.
