What is a common sign that someone may be going into shock?

Restlessness is indeed a common sign that someone may be going into shock. When a person is in shock, their body is not receiving enough blood flow, which can lead to a state of confusion or agitation. This restlessness can be an indication of the body’s attempt to cope with the stress of inadequate circulation and oxygen delivery to vital organs. As the condition progresses, other symptoms may appear, but initial signs often include changes in mental status, such as restlessness or anxiety.

Other options represent responses that are not typical signs of shock. Increased energy would not be expected in someone experiencing shock, as shock typically leads to weakness and fatigue. Bright red skin may indicate other conditions but is not a standard sign of shock, which more commonly presents as pale, cool, or clammy skin. Lack of response could occur at later stages of shock but is not an early warning sign. Therefore, restlessness is a key indicator to monitor when assessing someone for potential shock.
