Which sign indicates potential circulatory compromise at an injury site?

• A. Numbness
• B. Warm skin
• C. Cooler temperature than the other limb
• D. Normal color

Answer: (C)

When assessing for circulatory compromise at an injury site, the key clue is how well blood is reaching the tissue. If the injured area feels cooler than the other limb, it indicates reduced blood flow and potential ischemia. That cooling happens because warm blood isn’t perfusing the area effectively, which can lead to tissue damage if not addressed. Warm skin suggests normal perfusion or inflammation, not compromised circulation, and normal color implies adequate blood flow. Numbness can result from nerve issues and isn’t a direct indicator of circulation status by itself. So the cooler temperature specifically points to possible circulatory problems.
