The correct answer is B) Administer fluids. The primary treatment for traumatic shock is to restore fluid volume and maintain circulation. Administering fluids, such as an IV of saline solution, helps replace blood and fluid loss to prevent further cardiovascular complications from shock. The other options are not the primary treatments for traumatic shock. CPR (A) is only necessary if the victim is unconscious and not breathing. Cooling the body (C) and keeping the victim sitting up (D) are secondary measures that may be taken, but do not directly address the fluid loss and circulatory issues associated with shock.
