A. Cerebral contusions may coalesce to form an 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
E. The associated brain damage is more severe in epidural hematomas - ANSWER-
A. Cerebral contusions may coalesce to form an intracerebral hematoma
EM: Epidural, middle meningeal

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 need more info on chest, not abdomen
, 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
B. Manuevers to prevent necrosis of the skin
C. Extremity compartment syndrome release
D. Ensuring adequate oxygenation and ventilation
E. Evaluation for occult crush syndrome - ANSWER-D. Ensuring adequate
oxygenation and ventilation
(ABC's)
A 22 year old male sustains a shotgun wound to the shoulder and chest at close
range. His BP is 80/40 and HR 130. After 2 L of crystalloid solution are rapidly
infused, his BP increases to 122/84 and HR decreases to 100. He is tachypneic
with RR of 28. On PE, his breath sounds are decreased at the left upper chest with
dullness on percussion. A large caliber tube thoracostomy is inserted into the fifth
intercostal space with the return of 200 mL of blood and no air leak. The most
appropriate next step is:
A. Insert a foley catheter
B. Begin to transfuse O negative blood
C. Perform thoracotomy
D. Obtain a CT Chest/Abd
E. Repeat the physical exam of the chest - ANSWER-E. Repeat the physical exam
of the chest
decreased breath sounds w/dullness -> hemothorax, need tube to drain
