Question

Quizplus · Accepted Answer

Edema at the injured site is likely to occur due to an increase in fluid accumulation in the area, which causes swelling. Vasoconstriction (A) would result in reduced blood flow to the area and exacerbate the injury. Decreased RBC concentration (B) is not likely, as red blood cells do not typically migrate from the site of injury. Fluid movement from tissue to vessels (C) is also not likely, as the injury has caused fluids to accumulate and lead to swelling.
