A person has been injured and is responsive. You obtain consent to check the victim for life-threatening conditions. What life-threatening condition would require you to immediately summon EMS personnel?A. Minor cuts and scrapesB. Persistent chest painC. Minor headacheD. Swollen ankle

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.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
