Which of the following is an early sign of shock?

1. High blood pressure

2. Restlessness

3. Decreased respiratory rate

4. Increased skin temperature

The correct answer is: Restlessness

Restlessness is recognized as an early sign of shock due to the body's response to inadequate perfusion and oxygenation of tissues. In the initial stages of shock, individuals may exhibit anxiety, disorientation, or an overall sense of unease as their body struggles to maintain function. This state of heightened arousal reflects the body's attempt to cope with stress and may manifest as restlessness. In contrast, high blood pressure is not typically associated with early shock; instead, blood pressure may decrease as shock progresses. A decreased respiratory rate is not characteristic of early shock, as individuals usually experience an increased rate in response to distress. Similarly, increased skin temperature does not indicate shock; rather, the skin may feel cool or cold as blood is diverted from the extremities to vital organs. Thus, restlessness stands out as a clear and significant early indicator of impending shock.
