Question: 1 / 400

What is a common sign of shock in a patient?

Bradycardia

High blood pressure

Cooling of the extremities

A common sign of shock in a patient is the cooling of the extremities. Shock occurs when there is inadequate blood flow to the body's tissues, which can lead to a decrease in perfusion. As the body attempts to conserve blood flow to vital organs, peripheral circulation diminishes, resulting in cooler extremities. This can often manifest as cold or clammy hands and feet as the body's priorities shift to maintaining the function of essential organs such as the heart and brain.

In contrast, bradycardia and high blood pressure are not typical signs of shock; in fact, shock often presents with tachycardia and hypotension. Increased energy levels are also contrary to what one would expect during shock, as patients typically exhibit signs of weakness, lethargy, or altered mental status due to inadequate blood flow and oxygenation to the body's tissues.
