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?

Choice A rationale Purulent drainage, commonly known as pus, is a thick, opaque, and often yellow, green, or brown exudate. This type of drainage is indicative of a bacterial infection because it contains a high concentration of leukocytes, specifically neutrophils, dead bacteria, and tissue debris. The presence of yellow, thick drainage post-cholecystectomy strongly suggests an inflammatory and infectious process in the wound bed, necessitating prompt reporting to the healthcare provider for evaluation and treatment. Choice B rationale Serous drainage is a thin, watery, and clear or light yellow/straw-colored fluid. It typically consists of serum, which is the clear part of the blood devoid of clotting factors. Serous fluid is considered a normal finding in the early stages of wound healing and represents plasma leakage from capillaries due to the inflammatory response. This type of drainage is not associated with the thick, yellow quality described. Choice C rationale Sanguineous drainage is fresh, bright red, and bloody, indicating the presence of a significant amount of red blood cells from active bleeding. This type of drainage is most common in deep wounds or immediately after surgery when small blood vessels are damaged. While bleeding may occur postoperatively, it does not account for the thick, yellow consistency characteristic of infection. Choice D rationale Serosanguineous drainage is a thin, watery, pinkish fluid composed of a mix of serous fluid and blood. The pink color results from the presence of a small number of red blood cells mixed with the clear, yellow serum. This is a common and expected finding in the middle stages of healing or from a surgical drain, but it is less thick and less yellow than the purulent drainage described.
