In this case, the life-threatening condition that would require calling EMS personnel immediately is persistent chest pain (option B).

Explanation:

Closed chest trauma should be considered a medical emergency because of vital structures in the chest such as the heart, lungs, great vessels, or their associated structures.

Persistent chest pain after an injury may be caused by broken ribs, hemopneumothorax -blood and air in the pleural space- lung contusion, or other injuries that may occur to the organs of the chest, and which are life-threatening.

In the presence of persistent chest pain, EMS services should be called to transfer the patient to a hospital facility where he or she can be examined and cared for properly.
