Which signs are most commonly associated with hemorrhagic shock in a casualty?

• A. Fever And Rash
• B. Hyperactivity And Flushed Skin
• C. Tachycardia, Hypotension, Cool Clammy Skin, and Altered Mental Status
• D. Epistaxis And Coughing

Answer: (C)

In hemorrhagic shock, significant blood loss lowers the circulating volume, causing reduced tissue perfusion. The body tries to maintain blood flow to essential organs by activating the sympathetic system, which leads to a fast heart rate and constricted blood vessels. That combination produces tachycardia, hypotension, and skin that is cool and clammy. As perfusion to the brain declines, mental status can change, ranging from confusion to agitation or lethargy. This set of signs—rapid pulse, low blood pressure, cool/clammy skin, and altered mental status—fits the classic picture of shock from blood loss and is what clinicians look for in casualty assessment.

Fever and rash suggest infection or inflammatory processes rather than acute blood-volume loss causing shock. Hyperactivity with flushed skin can occur in other conditions and does not reliably indicate hemorrhagic shock, which typically presents with cool, pale or clammy skin. Epistaxis and coughing describe bleeding sources or symptoms, not the systemic signs of shock itself.
