Which skin finding is commonly observed in hypovolemic shock?

• A. Warm, flushed skin
• B. Pale, cool, mottled skin
• C. Petechiae
• D. Jaundiced skin

Answer: (B)

Hypovolemic shock lowers the amount of circulating blood, so the body activates reflex vasoconstriction to keep blood flow to the brain and heart. That constriction reduces blood flow to the skin, making it cool and pale. As shock progresses and perfusion becomes uneven, the skin can take on a mottled appearance. This combination—pale, cool, mottled skin—is a hallmark of hypovolemic shock. Warm, flushed skin would suggest vasodilation, as seen in distributive shocks like sepsis or anaphylaxis. Petechiae point to bleeding under the skin from platelet problems or DIC, not the primary pattern of hypovolemia. Jaundiced skin indicates bilirubin buildup from liver issues or hemolysis, not acute shock physiology.
