Which finding is observed in cardiogenic shock?

• A. Slow, bounding pulse
• B. Cold, clammy skin
• C. Increased blood pressure
• D. Hyperactive bowel sounds

Answer: (B)

In cardiogenic shock the heart’s pumping ability is severely reduced, leading to low cardiac output and systemic undervascular perfusion. To preserve blood flow to the brain and heart, the body constricts peripheral vessels, which makes the skin feel cold and clammy. That cool, clammy skin is a classic sign of this condition. The pulse is typically fast because the body tries to compensate for the low output, not slow or bounding. Increased blood pressure is unlikely in cardiogenic shock, as blood pressure tends to be low. Hyperactive bowel sounds don’t fit, since reduced gut perfusion usually causes decreased bowel activity. So the cold, clammy skin best reflects the underlying physiology of cardiogenic shock.
