A 22 year old male is brought by ambulance to a small
community hospital after falling from the top of an 8 foot
ladder. Initially, he was found to have a large right
pneumothorax. A chest tube was inserted and connected
to an underwater seal drainage collection system with
negative pressure. A repeat CXR demonstrates a residual,
large right pneumothorax. After transferring the patient to a
verified trauma center, a third chest x-ray reveals a
persistent right pneumothorax. The chest tube appears to
be functioning and in good position. He remains
hemodynamically normal with no signs of respiratory
distress. The most likely cause for the persistent right
pneumothorax is:
A. Flail chest
B. Diaphragmatic injury
C. Pulmonary contusion
D. Esophageal perforation
E. Tracheobronchial injury - Answer-E. Tracheobronchial
injury

Which of the following is LEAST reliable for diagnosing
ESOPHAGEAL intubation?
A. symmetrical chest wall movement
B. end-tidal CO2
C. bilateral breath sounds
D. oxygen saturation >92%
E. ETT above carina on chest x-ray - Answer-D. oxygen
saturation >92%
-> if it says ESOPHAGEAL, go with this answer
Which of the following signs necessitates the need for a
definitive airway in severe trauma patient?
A. facial lacerations
B. repeated vomiting
C. severe maxillofacial trauma
D. sternal fracture

Which of the following statements are correct?

intracerebral hematoma
B. Epidural hematomas are usually seen in the frontal
region
C. Subdural hematomas are caused by injury to the
middle meningeal artery
D. Subdural hematomas typically have a lenticular shape
on CT

An 18 year old male is brought to the ED after being shot.
He has one bullet wound just below the right clavicle and
another just below the costal margin in the right posterior
axillary line. His blood pressure is 110/60, heart rate of 90,
and respiratory rate of 34. After ensuring a patent airway
and inserting 2 large caliber IV lines, the next most
appropriate step is to:
A. Obtain a portable chest x-ray
B. Administer a bolus of additional IV fluid
C. Perform a laparatomy
D. Obtain an abdominal CT scan
E. Perform diagnostic peritoneal lavage - Answer-A.
Obtain a portable chest x-ray

Which of the following should be performed FIRST in any
patient whose injuries may include multiple closed
extremity fractures?
A. A thorough assessment of four limb perfusion
