A. Normal white blood cell count: In wound sepsis, the white blood cell count is typically elevated as part of the body's immune response to infection, not normal.
B. Fever and chills: Fever (hyperthermia) and chills are common signs of systemic infection, including wound sepsis. They indicate an inflammatory response and activation of the body's defense mechanisms.
C. Decreased pain at the wound site: Increased pain at the wound site is more commonly associated with wound infection, not decreased pain.
D. Redness and swelling: Redness (erythema) and swelling (edema) are local signs of inflammation and can be present in infected wounds, but they are not specific to wound sepsis and may occur in non-infected wounds as well.
