Which finding most specifically supports a diagnosis of cardiogenic shock?

• A. Pedal edema and JVD
• B. Sweating and flushed skin
• C. Warm, dry skin with normal cap refill
• D. Large, irregular pupils

Answer: (A)

In cardiogenic shock, the heart’s pumping ability is so compromised that blood backs up in the venous system while forward flow to the tissues drops. Pedal edema and jugular venous distention are direct signs of that backward congestion and elevated venous pressures, which is why this finding most specifically supports a cardiogenic etiology. The sweating and flushed skin reflect sympathetic activation or vasodilation that can occur in various shock states, not specifically tied to heart pump failure. Warm, dry skin with normal cap refill suggests adequate perfusion or a different phase, and large, irregular pupils point to neurologic or toxic issues rather than cardiogenic shock.
