What signs suggest hypovolemic shock in a trauma patient?

• A. Tachycardia, hypotension, cool clammy skin, delayed capillary refill, altered mental status
• B. Hypertension with warm flushed skin
• C. Normal mental status with flushed skin
• D. Bradycardia with cool dry skin

Answer: (A)

Hypovolemic shock from trauma happens when blood loss reduces circulating volume, leading to inadequate tissue perfusion. The body compensates by increasing heart rate and constricting blood vessels to preserve blood flow to vital organs. That compensation produces tachycardia and cool, clammy skin. As perfusion worsens, capillary refill is delayed and mental status changes due to reduced brain oxygen delivery. Hypotension tends to appear later as volume loss becomes substantial.

The combination of tachycardia, hypotension, cool clammy skin, delayed capillary refill, and altered mental status fits this pattern well. Hypertension with warm flushed skin points to other shock types or conditions; normal mental status with flushed skin doesn’t reflect the perfusion deficits seen in shock; bradycardia with cool dry skin is not typical of hypovolemic shock, which usually presents with a rapid heart rate and often moist, cool skin.
