question 5

Multiple Choice

What physiologic process can result in excessive burn edema and shock in a patient with injuries totaling more than 50% total body surface area (TBSA) burn?

• A) The heat from the burn leads to immediate vascular wall destruction and extravasation of intravascular fluid.
• B) A positive interstitial hydrostatic pressure occurs in the dermis leading to burn wound edema.
• C) Plasma colloid osmotic pressure is decreased because of protein leakage into the extravascular space.
• D) Capillary permeability decreases in burned and unburned tissue, leading to hypovolemia.
