A flail chest occurs when a person suffers a double fracture of at least:

• Two adjacent ribs

• Three adjacent ribs

• Four adjacent ribs

• Five adjacent ribs

When a patient named Arjun is put on mechanical ventilation to stabilize a flail chest, how much time generally is needed for adequate bone healing to occur?

• 5 to 10 days

• 10 to 15 days

• 15 to 20 days

• 20 to 25 days

Which of the following are the clinical manifestations of a flail chest?

1. During inspiration the fractured ribs are pushed inward
2. During expiration the ribs bulges outward
3. During inspiration the fractured ribs are pushed outward
4. During expiration the ribs bulges inward

• 1 and 2

• 3 and 4

• 2 and 3

• 1 and 4

Which of the following may cause a pneumothorax?

4. Blebs

• 1 and 2 only

• 2 and 3 only

• 2, 3, and 4 only

• 1, 2, 3, and 4

The physician usually elects to evacuate the intrathoracic gas when the pneumothorax is greater than:

• 5%

• 10%

• 15%

• 20%

When gas moves between the pleural space and the atmosphere during a ventilatory cycle, the patient is said to have a(n):

• Closed pneumothorax

• Iatrogenic pneumothorax

• Sucking chest wound

• Valvular pneumothorax

When gas enters the pleural space during inspiration but is unable to leave during expiration, the patient is said to have a(n):

1. Iatrogenic pneumothorax

2. Valvular pneumothorax

3. Tension pneumothorax

4. Open pneumothorax

• 1 only

• 3 only

• 2 and 3 only

• 3 and 4 only

Continuous bubbling in which chamber is indicative of an air leak?

• Vacuum chamber

• Tension chamber

• Water-seal chamber

• Suction control chamber

For a pneumothorax, a chest tube is inserted where?

• The eighth intercostal space

• The second intercostal space.

• On the proximal portion of the fifth intercostal space

• Distal to the injury

ROM exercises can prevent which complication of chest tubes

• Back pain

• Frozen shoulder

• Elevated ICP

• Infection
