Which of the following is NOT a sign or symptom of life-threatening bleeding?

Bruising in the affected area is not a sign or symptom of life-threatening bleeding because it typically indicates a more localized injury rather than severe blood loss. Bruising occurs when small blood vessels under the skin are damaged, allowing blood to leak into the surrounding tissues. While it can be serious depending on the context, it does not directly point to the critical nature of bleeding that requires immediate intervention.

On the other hand, blood that is spurting or flowing freely, failing to clot despite attempts to control it, and large amounts of blood loss are all clear indicators of life-threatening conditions. These signs suggest that there may be significant damage to major blood vessels or organs, necessitating urgent medical attention. Knowing the difference between these symptoms is crucial for effective first aid response.
