What is the primary intent of cold application immediately after injury?

• A. Increase bleeding
• B. Reduce area of secondary injury
• C. Increase tissue temperature
• D. Promote heat production

Answer: (B)

Cold therapy right after injury is used to limit secondary tissue damage. After the initial trauma, processes like inflammation, edema, and reduced oxygen delivery can cause additional cell death beyond what was immediately injured. Cooling slows cellular metabolism, so tissues need less oxygen and energy, which helps prevent a larger area from becoming damaged. It also causes vasoconstriction, reducing bleeding and the buildup of edema, and it dampens the inflammatory response and nerve signaling, which helps protect surrounding tissue and reduce pain. So the primary aim is to reduce the area affected by secondary injury, not to increase bleeding, raise tissue temperature, or promote heat production.
