Which of the following is considered a life-threatening condition?

Severe bleeding is considered a life-threatening condition because it can lead to significant loss of blood, causing shock and potentially resulting in death if not addressed promptly. The human body has a limited capacity to cope with blood loss. When a person loses a substantial volume of blood, vital organs can become deprived of oxygen and nutrients, leading to organ failure. Immediate medical intervention is critical to control the bleeding and restore adequate blood volume.

In contrast, minor cuts and bruises, a sprained ankle, and headaches generally do not pose an immediate threat to life. While they can be painful and may require treatment, they do not carry the same urgency as severe bleeding, which necessitates a rapid response to prevent serious complications.
