The nurse is auscultating a client’s breath sounds. Low-pitched grating and rubbing are noted on inhalation and exhalation. What will the nurse chart under assessment findings?

Number 3 is correct.

Rationale: Low-pitched grating and rubbing is indicative of friction rub. Rhonchi are either low-pitched, continuous rattling sounds (sonorous) or high-pitched and continuous (sibilant) sounds. Stridor occurs on inspiration and is loud, high-pitched crowing that can be heard without a stethoscope. Fine crackles are brief and high pitched.
