A nurse is collecting data from four clients who have wounds. The nurse should recognize that which client has a manifestation of a wound infection?

A. A client who has swelling and tenderness around the wound: Swelling and tenderness are classic local manifestations of infection due to the inflammatory response triggered by invading microorganisms. When bacteria proliferate in wound tissue, inflammatory mediators cause vasodilation and increased capillary permeability, leading to edema, warmth, and pain. These findings often accompany other signs of infection such as redness or purulent drainage. B. A client who has serosanguineous drainage from the wound: Serosanguineous drainage is a mixture of clear serous fluid and small amounts of blood, commonly seen in the early stages of wound healing. It usually appears thin and pink in color and reflects normal inflammatory processes after tissue injury. This type of drainage alone does not indicate infection. C. A client who has urticaria and itching around the wound: Urticaria and itching are more commonly associated with allergic reactions or hypersensitivity responses rather than infection. These symptoms may occur due to contact with adhesives, topical medications, or dressing materials used in wound care. While uncomfortable, they do not indicate bacterial invasion. D. A client who has a large brown scab over the wound: The presence of a scab represents dried blood and exudate forming a protective crust over the wound surface. This natural barrier protects the underlying tissue during the healing process and is commonly seen in superficial wounds. Scabs are not considered a direct sign of infection.
