Which skin sign most commonly indicates poor peripheral perfusion in shock?

• A. Cool, pale skin
• B. Warm, flushing skin
• C. Dry, leathery skin
• D. Red, swollen skin

Answer: (A)

When shock reduces overall blood flow, the body constricts vessels in the skin to preserve blood for vital organs. This makes the skin cool to the touch and pale, a classic sign that peripheral perfusion is poor. Warm, flushed skin would suggest the skin is receiving blood despite other problems, which isn’t the typical pattern of poor perfusion. Dry or leathery skin isn’t a reliable indicator of current perfusion status, and red, swollen skin points to local inflammation rather than systemic perfusion failure. So cool, pale skin best reflects the diminished peripheral perfusion seen in shock.
