What should you do if a victim shows signs of shock?

Keeping the victim warm and still is the correct action to take if someone shows signs of shock. Shock is a critical condition that occurs when the body is not getting enough blood flow, which can result from various causes such as severe injury, blood loss, or dehydration. Maintaining warmth helps prevent the body from losing heat, which is vital since shock can lead to a drop in body temperature, further complicating the situation.

Keeping the victim still is also essential to avoid movement-related stress on their body, which could exacerbate their condition. It helps in conserving energy and preventing additional injury, particularly if the shock is a result of trauma.

The other options do not support effective first aid for shock. Moving a victim to a cooler area can worsen their condition by increasing heat loss. Providing food and drink could be dangerous since the victim might need surgical intervention or might not be able to swallow safely due to their state. Encouraging them to stay active could lead to additional physical stress and higher oxygen demand, which is counterproductive to their recovery.
