A nurse assesses an adult client's breath sounds and auscultates a popping sound during inspiration. How should the nurse document this finding?

Choice A reason: Crackles are described as popping sounds heard during inspiration. They are caused by the sudden opening of small airways and alveoli that had collapsed or were filled with fluid. Crackles are commonly associated with conditions such as pneumonia, heart failure, or pulmonary fibrosis. Choice B reason: Pleural friction rub is a grating sound heard during both inspiration and expiration, caused by inflamed pleural surfaces rubbing together. It does not sound like popping and is distinctly different from crackles. Choice C reason: Bronchovesicular sounds are normal breath sounds heard over the major bronchi. They are medium-pitched and not popping in nature. Documenting popping sounds as bronchovesicular would be inaccurate. Choice D reason: Crepitus refers to a crackling sensation felt under the skin due to air trapped in subcutaneous tissue, not a sound heard during auscultation of the lungs. It is palpated, not auscultated.
