What are the signs of shock?

The signs of shock encompass a range of physiological responses that occur when the body's organs and tissues do not receive adequate blood flow and, consequently, oxygen. The correct set of indicators includes falling blood pressure, a rapid pulse, and rapid respirations, along with cold, moist pale skin.

Falling blood pressure is a hallmark sign of shock because it indicates that the circulatory system is unable to maintain adequate perfusion to the vital organs. A rapid pulse occurs as the body attempts to compensate for decreased blood volume or circulation by increasing heart rate to maintain blood flow. Rapid respirations are also a compensatory mechanism, reflecting the body's effort to enhance oxygen delivery in response to the crisis. Additionally, cold, moist, pale skin can result from vasoconstriction, where blood vessels narrow to redirect blood flow to vital organs, leaving less blood perfusing the skin.

The other choices do not accurately reflect the physiological changes associated with shock. For instance, rising blood pressure is not consistent with shock, as it typically indicates good blood flow and circulation. Similarly, a pulse that is slow and respirations that fall would suggest a different set of medical concerns rather than shock. Warm skin does not align with shock symptoms, as the body's response tends to involve cool and
