What are the S/S of a tension pneumothorax? - correct answer - -
Severe respiratory distress
- Markedly diminished or absent breath sounds on affected side
- hypotension
- Distended neck, head and upper extremity veins-may not be
clinically appreciated if significant blood loss present
- Tracheal deviation - shift toward uninjured side (LATE sign)
- Cyanosis (LATE sign)
Define Hemothorax. - correct answer - Accumulation of blood in
the pleural space.
What are the S/S of Hemothorax? - correct answer - - Dyspnea,
tachypnea
- Chest pain
, Page | 2
- Signs of shock
- Decreased breath sounds on injured side
- Dullness to percussion on the injured side
What is a pulmonary contusion? - correct answer - They occur as
a result of direct impact, deceleration or high-velocity bullet
wounds. It develops when blood leaks into lung parenchyma,
causing edema + hemorrhage. This usually develops overtime
and not immediately.
What are the S/S of pulmonary contusion? - correct answer - -
Dyspnea
- Ineffective cough
- Hemoptysis
- Hypoxia
- Chest pain
- Chest wall contusion or abrasions
What happens to a ruptured diaphragm? - correct answer -
Potentially life-threatening, results from forces that penetrate the
body. Left hemidiaphragm is more susceptible to injury because
the right side is protected by the liver.

- Herniation of abdominal contents
- Respiratory compromise b/c impaired lung capacity +
displacement of normal tissue.
- Mediastinal structures may shift to opposite side of injury
What are S/S of a ruptured diaphragm? - correct answer -
(Anything below the nipple line and should be evaluated for
potential diaphragmatic injury).
- Dyspnea or orthopnea
- Dysphagia
- Abdominal pain
- Sharp epigastric or chest pain radiating to left shoulder (Kehr's
sign)
- Bowel sounds heard in lower middle chest
- Decreased breath sounds on injured side
What are S/S with tracheobronchial injury? - correct answer -
Blunt trauma. "Clothesline-type" injuries.
- Dyspnea, tachypnea
- Hoarseness
- Hemoptysis
- Subcutaneous emphysema in neck, face, or suprasternal area
, Page | 4
- Decreased or absent breath sounds
- S/S of airway obstruction
What are S/S with blunt cardiac injury? - correct answer -
"Cardiac contusion" or "concussion." Common with MVC or falls
from heights.
- ECG (sinus tach, PVC's, AV blocks)
- Chest pain
- Chest wall ecchymosis
What are the S/S of pericardial tamponade? - correct answer - A
collection of blood in pericardial sac. As blood accumulates, it
exerts pressure on the heart, inhibiting or compromising
ventricular filling.
- Hyotension
- Tachycardia or PEA
- Dyspnea
- Cyanosis
- Beck's Triad (hypotension, distended neck veins + muffled heart
sounds)
- Progressive decreased voltage of conduction complexes on
ECG
