A nurse is assessing a client's wound dressing and observes a watery red drainage. The nurse should document this drainage as which of the following?

Rationale: A. Purulent drainage is thick, yellow, green, or brown, indicating infection due to the presence of white blood cells, bacteria, and debris. B. Sanguineous drainage is primarily blood, appearing bright red and thicker, not watery. C. Serous drainage is clear or pale yellow and watery, composed mostly of serum, not blood. D. Serosanguineous drainage is thin and watery with a pink to red color, indicating a mixture of blood and serous fluid. This is commonly seen in healing wounds.
