Which of the following is NOT a life-threatening situation?

Tenderness and swelling can indicate an injury or condition that requires medical attention, but in itself, it is not considered immediately life-threatening. Life-threatening situations typically involve conditions that can lead to death or severe harm if not addressed rapidly, such as severe external bleeding, which can lead to significant blood loss, and difficult breathing, indicating respiratory distress or failure. Unresponsiveness indicates a potential neurological emergency, where immediate intervention is critical to prevent deterioration. In contrast, tenderness and swelling may require a medical consultation but does not pose an immediate risk to life, making it the correct answer for this question.
