Which of the following is NOT a sign of shock?

In the context of recognizing shock, increased appetite is not typically associated with the condition. Shock is a critical state where the body's organs and tissues do not receive adequate blood flow, often leading to a variety of symptoms. These symptoms include weakness, fainting, and pale skin, all of which are indicators of inadequate circulation and oxygen delivery to vital organs.

Weakness can result from a lack of blood flow and energy being distributed to the muscles. Fainting often occurs when the brain does not receive enough blood supply, signaling a potential state of shock. Pale skin can occur due to constricted blood vessels as the body tries to divert blood to vital organs, resulting in a diminished blood supply to the skin.

Conversely, increased appetite would generally be indicative of a well-nourished and stable state, not a sign of distress or shock. Therefore, it stands out as the correct answer since it does not align with the typical physiological responses associated with shock.
