Two days after a patient undergoes abdominal surgery,his surgical incision is red and slightly edematous; it is oozing a small amount of serosanguineous (pink-tinged serous) fluid.On the basis of these data,what can you conclude? Select all that apply.

A) The wound is most likely infected.
B) This is a vascular response to inflammation.
C) Damaged cells are being regenerated.
D) Exudate formation is occurring.

During the vascular response phase of the inflammatory process,blood vessels constrict to control bleeding.Fluid from the capillaries moves into tissues,causing edema.The fluid and white blood cells that move to the site of injury are called exudates; this includes the serosanguineous exudate that commonly appears at surgical incisions.When a wound becomes infected,yellow,foul-smelling drainage may form at the site; there is no mention of pus in the scenario.Regeneration occurs when identical or similar cells replace damaged cells; although this may be occurring,you cannot prove it with the data given here.
