🔍 Key Concepts

• Pathophysiology of burns – what happens to fluids and blood vessels when skin is badly burned • Role of the skin in maintaining body fluids and acting as a barrier • How shock is defined – especially in trauma patients

💭 Think About

• Ask yourself: what does the skin normally prevent from leaving the body, and what changes when a large area is burned? • Which option describes something that can directly reduce the amount of circulating blood volume? • Consider: between temperature, emotions, pain, and fluid balance – which has the greatest effect on circulation and blood pressure in a burn victim?

✅ Before You Answer

• Identify which option directly leads to low circulating blood volume. • Decide which choice could most quickly result in low blood pressure and poor tissue perfusion (classic signs of shock). • Double-check that the option you pick affects the circulatory system, not just how the patient feels (pain, emotions).
