Which of the following is NOT an indication of a life-threatening illness or injury?

A seizure lasting 2 minutes may be concerning and warrants attention, but it does not necessarily indicate a life-threatening illness or injury by itself. It is important to monitor the situation, as prolonged seizures can lead to complications, but a single seizure of this duration can occur in a variety of contexts, some of which may not be immediately life-threatening.

On the other hand, the other scenarios present clear indicators of severe medical emergencies: a lack of pulse signifies cardiac arrest, spurting blood indicates a severe hemorrhage that could lead to hypovolemic shock, and bluish skin around the lips in an unconscious individual suggests a lack of oxygen—each of those conditions necessitates immediate medical intervention. Therefore, while addressing a seizure is critical, it does not reach the immediate urgency of the other described situations regarding potential life threats.
