A patient is being evaluated for severe burns to the torso and upper extremities, with edema around the burned areas. How should the nurse describe the underlying cause for this assessment finding?
1. inability of the damaged capillaries to maintain fluids in the cell walls
2. reduced vascular permeability in the burned area
3. decreased osmotic pressure in the burned tissue
4. increased fluids in the extracellular compartment
Correct Answer: 1
Burn shock occurs during the first 24–36 hours after the injury. During this period, there is an increase in microvascular permeability at the burn site. The osmotic pressure is increased, causing fluid accumulation. There is a reduction of fluids in the extracellular body compartments.
