Which of the following is NOT a symptom of shock?

Elevated blood pressure is not typically a symptom of shock. In fact, shock is characterized by a reduction in blood flow to vital organs, which often leads to hypotension or low blood pressure. This occurs because the body is unable to maintain adequate circulation due to various reasons, such as fluid loss, heart failure, or severe infection.

In contrast, tachycardia, pallor, and cyanosis are common signs observed in patients experiencing shock. Tachycardia can occur as the body attempts to compensate for reduced blood volume or pressure by increasing the heart rate. Pallor results from peripheral vasoconstriction as blood is redirected to vital organs. Cyanosis may develop due to inadequate oxygenation of the blood, reflecting poor perfusion. Understanding these symptoms is crucial for recognizing and managing shock effectively in clinical settings.
