ATCN 2020 Chapter 4 Thoracic Trauma
Exam 100% Correct!!
__________________ is the most serious consequence of thoracic trauma. - ANSWER Hypoxia
Posterior dislocation of the ______________________________ leads to airway obstruction -
ANSWER Posterior dislocation of the clavicals head leads to airway obstruction.
The majority of tracheobronchial tree injuries occur where? - ANSWER Occur within 1 inch of the
carina.
Incomplete expansion of the lung and continued large air leak after placement of a chest tube
suggests a tracheobronchial injury and placement of more than one chest tube may be necessary.
Blast injuries commonly produce severe injury to _______________________ interfaces. - ANSWER
Air-fluid interfaces.
The most common cause of a _______________________________________________ is
mechanical positive pressure ventilation in patients with visceral pleural injury. - ANSWER Tension
Pneumothorax
Patients who suffer this type of injury and who are spontaneously breathing often manifest extreme
tachypnea and air hunger, whereas patients who are mechanically ventilated manifest hemodynamic
collapse. - ANSWER Pneumothorax
__________________________________________ > 1500ml of blood or 1/3 of patients blood
volume in one side of the chest with a. ________________________________________. Can
significantly compromise respiratory efforts. - ANSWER Massive Hemothorax
Usually occurs from penetrating trauma
May occur from blunt trauma
_______________________________ (can be seen in the following injuries)
Cardiac Tamponade
Tension Pneumothorax
, Profound hypovolemia - ANSWER PEA
List all the potential causes of PEA - ANSWER Hemothorax
Hypoxia
Hydrogen Ion ( Acidosis)
Hypo / Hyperkalemia
Hypoglycemia
Hypothermia
Toxins
Thrombus (coronary / Pulmonary)
___________________________________________ is a rapid and accurate (90% -95%) method of
imaging the heart and pericardium. - ANSWER FAST - Focused Assessment with Sonography for
Trauma
When ___________________________________________________________ is used as a
temporizing maneuver, the use of a large, over the needle catheter is ideal, but the urgent priority is
to aspirate blood from the pericardial sac. - ANSWER Subxiphoid pericardiocentesis
Ideally a person known to have a ____________________________________ should not undergo
general anesthesia or receive positive pressure ventilation without having a chest tube inserted. -
ANSWER Pneumothorax
A patient with a ___________________________________ should also undergo decompression
before transport at high altitudes. - ANSWER Pneumothorax
_________________________________________ may be associated with a hemothorax. - ANSWER
Thoracic Spine fractures
____________________________________________ is defined as two or more adjacent rib
fractures in two or more places - ANSWER Flail Chest Segment
In adults, ______________________________________________ is most often encountered with
concomitant rib fractures, and it is the most common potentially lethal chest injury. - ANSWER
Pulmonary Contusion
