thorasic trauma

What is the most common cause of traumatic pneumothorax?

• Blunt chest trauma

• Penetrating chest trauma

• Rib fractures

• Diaphragmatic rupture

Which of the following is a clinical sign of tension pneumothorax?

• Hyperresonance on percussion and tracheal deviation

• Dullness on percussion and midline trachea

• Hypotension and bilateral breath sounds

• Bradycardia and decreased respiratory effort

A flail chest is defined as:

• Fracture of two or more adjacent ribs in two or more places

• Fracture of one rib in two or more places

• Bilateral rib fractures with associated hemothorax

• Fracture of three ribs in one place with lung contusion

Which of the following is an appropriate initial management step for a suspected tension pneumothorax?

• Endotracheal intubation and positive-pressure ventilation

• Chest tube insertion at the 5th intercostal space, anterior axillary line

• Needle decompression at the 2nd intercostal space, midclavicular line

• CT scan of the chest before intervention

Which of the following injuries is most likely to result in cardiac tamponade?

• Aortic rupture

• Myocardial contusion

• Penetrating trauma to the chest

• Rib fractures

A widened mediastinum on chest X-ray in a trauma patient should raise suspicion of:

• Cardiac tamponade

• Pulmonary contusion

• Traumatic aortic rupture

• Simple pneumothorax

Which of the following is the most appropriate diagnostic test for a patient with suspected blunt cardiac injury?

• Electrocardiogram (ECG)

• Chest X-ray

• Echocardiography

• CT angiography

Which of the following is a sign of hemothorax on physical examination?

• Hyperresonance on percussion

• Decreased breath sounds and dullness on percussion

• Tracheal deviation away from the affected side

• Subcutaneous emphysema

The management of a large hemothorax typically involves:

• Needle decompression

• Chest tube insertion

• Pericardiocentesis

• Endotracheal intubation

A patient presents with paradoxical chest wall movement and severe respiratory distress following a high-speed motor vehicle accident. What is the most likely diagnosis?

• Tension pneumothorax

• Flail chest

• Cardiac tamponade

• Diaphragmatic hernia
