Which of the following is a sign of shock?

A rapid, weak pulse is indeed a sign of shock. When a person is in shock, their body is not able to maintain adequate blood flow, which can result from various causes such as severe injury, infection, or allergic reactions. The body compensates for this lack of blood flow by increasing the heart rate in an attempt to deliver more oxygen to vital organs, but the pulse may feel weak due to the insufficient volume of blood being pumped effectively.

In shock, other physiological responses also occur, such as changes in skin temperature and moisture. For example, individuals may develop cool, clammy skin rather than warm and dry skin, which can be observed in other conditions. Understanding these signs is crucial, as early recognition of shock can lead to timely medical intervention. The awareness of symptoms such as a rapid, weak pulse is vital for anyone providing first aid or assisting in emergencies.
