Thoracic Trauma Test Review
2
Question
  • What are the first two leading causes of death in motor vehicle accidents?
3
Answer
  • 1st – head trauma
  • 2nd – thoracic trauma
4
Question
  • What should you do FIRST after discovering a “sucking chest wound”?
5
Answer
  • Cover with a gloved hand and stop your assessment to apply a 3 sided occlusive dressing
6
Question
  • What are the findings of a tension pneumothorax?
7
Answer
  • Absent (or extremely decreased breath sounds on affected side
  • Positive JVD
  • Tracheal shift to good lung (late)
  • Hyperresonance to percussion
8
Question
  • True or False
    • Hypothermia is possible from any patient in a shock state, and these patients should be covered with a blanket to prevent heat loss.
9
Answer
  • True
10
Question
  • True or False
    • Failure to adequately assess lung sounds would most negatively impact a differential diagnosis between a pneumothorax and a hemothorax.
11
Answer
  • False
    • These are very difficult to distinguish in the prehospital setting anyway.  Not assessing lung sounds would more likely affect the differential diagnosis of a tension pneumothorax and a pericardial tamponade.
12
Question
  • Of the common 14 thoracic trauma injuries discussed in class, which one has the most obscure signs and symptoms and is most commonly diagnosed based on the MOI of the accident?
13
Answer
  • Myocardial contusion
14
Question
  • When should a tension pneumothorax be decompressed?
15
Answer
  • On scene as soon as it is discovered.
    • You should consider stopping your trauma assessment to manage this injury!
16
Question
  • What would be the greatest negative result of misdiagnosing an injury as a pericardial tamponade and not a tension pneumothorax?
17
Answer
  • Delay in decompressing the chest
18
Question
  • What is the cause of hypotension in a patient with a tension pneumothorax?
19
Answer
  • Increased intrathoracic pressure decreases the blood return to the heart.
20
Question
  • What is the best method to distinguish a pneumothorax verses a hemothorax?
21
Answer
  • Chest percussion
22
Question
  • What causes patechiae in cases caused by traumatic asphyxia?
23
Answer
  • The backflow of blood damaging microcirculation
24
Question
  • True or False
    • The treatment priority for a tracheobronchial tear is positive pressure ventilations via an endotracheal tube.
25
Answer
  • False
    • PPV and ETT should be avoided and airway maintenance with suctioning should become a priority to avoid subcutaneous emphysema
26
Question
  • What is the most common location for disruptions in anatomy secondary to a tracheobronchial injury?
27
Answer
  • Near the Carina
28
Question
  • What is the greatest life threat from a traumatic esophageal rupture?
29
Answer
  • Peritonitis damaging mediastinal organs
30
Question
  • What causes the increase in blood pressure secondary to dissecting aortic aneurysms?
31
Answer
  • Sympathetic nerve fibers response to stretching of the aorta
32
Question
  • What diagnosis can be made form a patient suffering blunt force trauma to the chest with decreased breath sounds, no JVD, lung lobe rales or crackles, decreased SpO2, tachypnea and tachycardia?
33
Answer
  • Pulmonary contusion
34
Question
  • What are the common signs and symptoms of a diaphragmatic rupture?
35
Answer
  • Hollow appearing abdomen
  • Bowel sounds in the chest
  • Decreased breath sounds
  • S/S similar to a tension pneumothorax
36
Question
  • What is Kussmaul’s sign?
  • (NOT Kussmaul’s respirations!)
37
Answer
  • Decrease in JVD with inspiration with a patient suffering from a pericardial tamponade.
38
Question
  • How much fluid is needed to fill the pericardium before s/s of  a pericardial tamponade develop?
39
Answer
  • 200 – 300mL
40
Question
  • Which of the pulmonary injuries is typically the slowest to develop?
41
Answer
  • Pulmonary contusion
42
Question
  • Of the skeletal related thoracic injuries, which one most likely will require positive pressure ventilations?
43
Answer
  • Flail Segment
44
Questions
  • Which ribs are most commonly fractured?
45
Answer
  • Ribs 4 – 9 along the posterior axillary line
46
Question
  • What is the best treatment for a flail segment?
47
Answer
  • Positive pressure ventilations
48
Question
  • What are the most common s/s with a hemothorax?
49
Answer
  • Diminished breath sounds
  • Absent JVD
  • Hyporesonance or dull percussion
  • s/s of hypovolemic shock
50
Question
  • What chest injury is the most common and the least severe?
51
Answer
  • Chest wall contusion
52
Question
  • At what landmarks should a needle chest decompression be performed?
53
Answer
  • 2nd or 3rd intercostal space, superior to the rib in the midclavicular line.
54
Question
  • What is the tidal volume for the average adult single breath?
55
Answer
  • 500mL
56
Question
  • What are the three divisions of the sternum from superior to inferior?
57
Answer
  • Manubrium, Body, and Xiphoid process
58
Question
  • What is the most critical intervention for a patient suffering from a pericardial tamponade?
59
Answer
  • Pericardiocentesis
60
Question
  • True or False
    • PPV is contraindicated in traumatic esophageal injury.
61
Answer
  • False
    • Although it should be used with caution because of the risk of subcutaneous emphysema, PPV nor ETT is contraindicated if needed.  Blind intubation devices such as a Combitube are completely contraindicated.
62
Question
  • What are the common s/s of traumatic tracheal tearing?
63
Answer
  • Dyspnea
  • Cyanosis
  • Hemoptysis
  • Massive subcutaneous emphysema
