Subject: Chapter 30, Page 1104 Taxonomy: Recall Title: Chest Injuries The correct answer is: is commonly caused by blunt chest trauma.

An open pneumothorax is: Select one: A.the entry of air into the pleural space from a perforated lung. B.a fractured rib that perforates the tissue of the lung surface. C.an open chest wound through which air moves during breathing. D.extreme pleural pressure that causes the lung to rupture.

Subject: Chapter 30, Page 1103 Taxonomy: Recall Title: Chest Injuries The correct answer is: an open chest wound through which air moves during breathing.

When assessing a patient with a hemothorax, you will most likely find: Select one: A.ipsilateral tracheal deviation. B.jugular venous engorgement. C.distant or muffled heart tones. D.signs and symptoms of shock.
