Which of the following are signs and symptoms of shock?

The presence of cool, pale, sweaty skin, rapid weak pulse, and altered mental status (AMS) are classic signs and symptoms of shock. In a state of shock, the body experiences a significant decrease in blood flow to vital organs, leading to these symptoms as a result of inadequate perfusion. The skin may become cool and pale due to vasoconstriction, which the body uses to redirect blood flow to more critical areas such as the heart and brain. Sweating can occur as a response to stress or hypoperfusion. A rapid weak pulse indicates that the heart is struggling to compensate for low blood volume or pressure, while altered mental status reflects the brain's lack of sufficient oxygen and nutrients.

The other options include symptoms that are either not commonly associated with shock or do not represent the physiological changes seen during this critical condition. Identifying these signs correctly is crucial for timely intervention and management in emergency situations.
