Which of the following are signs and symptoms of shock?

The correct choice highlights the classic signs and symptoms of shock. Shock occurs when the body's organs and tissues do not receive enough blood and oxygen, which can lead to serious complications if not treated promptly.

A rapid heartbeat, often referred to as tachycardia, is a physiological response to compensate for decreased blood flow and elevated demand for oxygen by vital organs. Low blood pressure, or hypotension, indicates that the heart is struggling to pump effectively or that the volume of blood circulating is insufficient, both key indicators of shock. Clammy skin occurs due to peripheral vasoconstriction, where blood vessels narrow to prioritize blood flow to essential organs, resulting in cooler, moist skin. These signs together help form a clear picture of a patient in shock and should always be recognized as urgent medical conditions.

Other options present symptoms that are not consistent with the generalized presentation of shock, such as high blood pressure in one of the choices. Generally, high blood pressure does not align with the typical response in shock scenarios, where failure to maintain adequate perfusion usually results in decreased blood pressure.
