Which of the following is a sign of major, life-threatening external bleeding?

Blood spurting out of the wound is a clear indication of major, life-threatening external bleeding because it suggests that a major artery has been severed. This type of bleeding is typically bright red and can be pulsatile, meaning it comes out in bursts that coincide with the heartbeat. Such a situation requires immediate intervention to control the bleeding and prevent significant blood loss, which can lead to shock or death if not promptly managed. Understanding the urgency of this sign is critical for first responders and criminal justice officers in the field, as it directs them to prioritize treatment and transport the victim to a medical facility quickly.

In contrast, small puncture wounds, simple cuts and scrapes, or bleeding from minor scratches tend to involve less severe injuries that generally do not result in life-threatening blood loss. These types of injuries could often be treated with basic first aid measures without the immediate need for advanced medical care. Recognizing the difference between these various types of bleeding is crucial in prioritizing care during an emergency situation.
