Which statement best differentiates neurogenic shock from hypovolemic shock?

In shock, how the body responds reveals the underlying problem. Neurogenic shock comes from loss of sympathetic tone, often after a spinal injury, which causes widespread vasodilation and a drop in blood pressure. Because the sympathetic drive to the heart is reduced, the heart rate often slows (bradycardia). The peripheral vessels are dilated, so the skin tends to feel warm and dry. Hypovolemic shock, on the other hand, results from a loss of blood or fluid. The body compensates by activating the sympathetic system, which increases heart rate (tachycardia) and constricts peripheral vessels, leading to cool, clammy skin. Therefore, a statement describing hypotension with bradycardia and warm/dry skin best differentiates neurogenic shock from hypovolemic shock, since it reflects the hallmark combination of reduced heart rate and vasodilation seen in neurogenic shock, contrasting with the tachycardia and cool skin seen in hypovolemia. The other patterns (tachycardia with cool skin for neurogenic, or bradycardia with cool skin for hypovolemia) do not fit the typical physiologic responses.
