If a victim shows signs of shock and the injuries permit, what action should you take?

Elevating the feet 6 to 12 inches is the recommended action to help a victim showing signs of shock, as it aids in improving blood flow to vital organs. This position can assist with venous return by encouraging blood circulation back to the heart, which is critical in a state of shock where the body's organs may not be receiving an adequate blood supply.

In addition, this action can help stabilize the victim's condition until emergency medical services arrive. Ensuring that the feet are elevated can also help in managing symptoms such as lightheadedness, weakness, or confusion that might accompany shock.

While laying the victim flat on their back is generally acceptable, elevating the feet specifically targets the improvement of circulation in a way that can be particularly effective in shock cases. Immediate fluid administration would require medical supervision and equipment, making it a less appropriate option for a first responder on the scene. Keeping the victim cool is also not suitable, as maintaining a normal body temperature is important in managing shock.
