What is one of the first signs of shock?

• A. Confusion
• B. Rapid heart rate
• C. Cold clammy skin
• D. Fainting spells

Answer: (B)

One of the first signs of shock is a rapid heart rate. This occurs as the body attempts to compensate for decreased blood flow and oxygen delivery to vital organs. When the body is under stress, such as during shock, it activates its fight-or-flight response, leading to an increase in heart rate. This physiological response is aimed at improving circulation and maintaining blood pressure despite the underlying issues causing shock. Other options may occur as shock progresses or in different situations. For example, confusion can be a later sign as the brain begins to suffer from inadequate perfusion. Cold clammy skin is also associated with shock but tends to manifest as the condition worsens and blood flow is redirected away from the skin to preserve critical organ function. Fainting spells are typically indicative of more advanced shock, when the brain isn't receiving enough blood flow due to a significant drop in blood pressure. Thus, a rapid heart rate is a key early indicator that allows responders to assess the severity of a patient's condition in the context of potential shock.
