edema. Which of the following is the most likely cause of this
condition?
Answer: Increased capillary hydrostatic pressure
◉ A 10-year-old male is brought to the emergency room (ER)

is suffering from cerebral edema. This type of edema is referred to
as:
Answer: localized edema

confusion, and depressed reflexes. His wife indicates that he does
not follow the prescribed diet and takes his medication sporadically.
Lab results indicate hyperglycemia. Which assessment finding is
most likely to occur?
