Which of the following would you expect to see with second- and third-degree burns in the emergent phase?
  1. Decreased heart rate
  2. Increased blood pressure
  3. Elevated hematocrit levels
  4. Increased urinary output
Explanation
Answer: C - One would expect to find elevated hamatocrit levels in a patient in the emergent phase of second- or third-degree burns. 48 to 72 hours after injury, the emergent phase ends with the restoration of capillary permeability. Hemoconcentration from large fluid shifts leads to increased hematocrit.
