Cold, clammy skin is a sign of what during shock?

• A. Hyperperfusion
• B. Hypoperfusion
• C. Vasodilation
• D. Dehydration

Answer: (B)

Cold, clammy skin during shock reflects reduced tissue perfusion (hypoperfusion). When shock occurs, the body constricts peripheral vessels to preserve blood flow to vital organs like the brain and heart. That vasoconstriction lowers skin blood flow, making the skin feel cool and moist. This is different from a state of hyperperfusion, which would yield warm or flushed skin, and from vasodilation, which also tends to produce warm skin because vessels are dilated. Dehydration can contribute to shock by lowering blood volume, but the specific skin sign described points to diminished perfusion rather than just fluid loss.
