While auscultating a client's abdomen, the nurse hears a low-pitched blowing sound in the upper midline area. Which is the likely indication of this finding?

A. Hyperactive bowel sounds. Hyperactive bowel sounds are typically higher pitched and more frequent. B. Possible renal artery stenosis. This is the best choice as a low-pitched blowing sound can indicate a bruit from renal artery stenosis. C. Normal borborygmus sounds. Borborygmi are normal, loud, gurgling bowel sounds, not low-pitched blowing sounds. D. A minor variation. A low-pitched blowing sound should not be considered a minor variation as it can indicate a serious condition.
