A nurse is caring for a client who is 3 days postoperative following a cholecystectomy. The nurse suspects the client's wound is infected because the drainage from the dressing is yellow and thick. Which of the following findings should the nurse report as the type of drainage found?

A. Purulent drainage is thick, opaque, and yellow, green, or tan in color. It often indicates the presence of infection because it contains pus, which is made up of white blood cells, bacteria, and cellular debris. Yellow, thick drainage from a postoperative wound 3 days after surgery is a classic sign of wound infection and should be reported promptly. B. Sanguineous drainage consists primarily of fresh blood and appears bright red. It is commonly seen immediately after surgery or trauma and does not describe thick, yellow drainage. C. Serosanguineous drainage is a mixture of serum and blood, giving it a light pink or reddish appearance. It is common in the early stages of wound healing and is not thick or yellow. D. Serous drainage is clear, watery, and pale yellow. It is normal in the early phases of wound healing and is thin rather than thick, making it inconsistent with the findings described.
