Following back surgery one week ago, the client has yellow drainage with a foul odor coming from the incision. The nurse would document this drainage by which term?

Wound drainage is classified according to its characteristics, which reflect the underlying pathological process. Purulent drainage is thick, opaque, and has a yellow, green, or tan coloration along with a foul or malodorous smell. It contains dead white blood cells, bacteria, and cellular debris, and it indicates infection, which is consistent with the clinical picture of a surgical incision that is draining yellow, foul-smelling fluid one week postoperatively. Sanguineous drainage is bright red and consists primarily of fresh blood; it is typically seen in the early postoperative period or with active bleeding from a wound. Serosanguineous drainage is a mixture of serum and blood, appearing as a pale pink or watery pink fluid, and is normal in the first days after surgery. Translucent is not a standard clinical term for wound drainage classification; serous drainage, which is clear or pale yellow and watery, would be the term for clear exudate. Understanding wound drainage terminology enables accurate documentation and helps nurses recognize signs of wound infection early so that appropriate interventions, including notification of the provider and potential wound culture or antibiotic therapy, can be initiated promptly.
