1) Which of the following signs is LEAST reliable for diagnosing esophageal
intubation?
A. Symmetrical chest wall movement
B. End-tidal CO₂ presence (colorimetric/capnography)
C. Bilateral breath sounds
D. Endotracheal tube (ETT) tip above the carina on chest x-ray
Answer: D
Rationale: While a chest x-ray confirming that the tube is above the carina
can help verify depth of intubation, it is not a rapid or reliable indicator of
correct (tracheal vs. esophageal) placement. Direct confirmation of CO₂
with a capnography device is the most reliable immediate test to rule out
esophageal intubation.

2) Which of the following findings necessitates a definitive airway in a
severely injured trauma patient?
A. Facial lacerations
B. Repeated vomiting
C. Severe maxillofacial fractures
,D. Glasgow Coma Scale (GCS) score of 12
Answer: C
Rationale: Severe maxillofacial fractures compromise the airway and can
lead to airway obstruction. Definitive airway management (e.g., surgical
airway or intubation) is indicated. Repeated vomiting or a moderately
decreased GCS (≥9) are concerning but not absolute indications for a
definitive airway on their own.

3) In a mass-casualty scenario (e.g., aircraft crash with multiple injured
survivors), which of the following best states the overarching principle of
triage?
A. Establish a triage site within the internal crash perimeter.
B. Treat only the most severely injured patients first.
C. Treat the greatest number of patients in the shortest period of time.
D. Produce the greatest number of survivors based on available resources.
Answer: D
Rationale: Triage in mass-casualty incidents emphasizes maximizing
survival with the resources available. While treating the most severely
injured first is typical in routine trauma care, true mass-casualty triage
prioritizes the goal of saving the most lives overall.

4) Which of the following statements regarding traumatic intracranial
lesions is CORRECT?
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 (biconvex) shape on CT
scan.
Answer: A
Rationale: Cerebral contusions can evolve into larger intracerebral
hematomas. Epidural hematomas more often involve a temporal skull
fracture and the middle meningeal artery. Subdural hematomas typically
are crescent-shaped (not lenticular) on CT and usually result from venous
bleeding (bridging veins).

5) An 18-year-old male presents with gunshot wounds near the right
clavicle and in the right posterior axillary line below the costal margin. His
blood pressure is 110/60 mm Hg, heart rate 90/min, and respiratory rate
34/min. Airway is secured; two large-bore IV lines are placed. The NEXT
appropriate step is to:
,A. Obtain a portable chest x-ray
B. Perform laparotomy
C. Obtain an abdominal CT scan
D. Perform a diagnostic peritoneal lavage
Answer: A
Rationale: After initial airway and IV access, a rapid chest x-ray helps
identify pneumothorax, hemothorax, or significant chest injury—particularly
crucial with a gunshot wound near the clavicle. Managing thoracic injuries
takes priority before investigating the abdomen.

6) A 47-year-old fell 20 feet and landed straddling a fence. He has
extensive perineal bruising and blood at the external urethral meatus. The
initial diagnostic study to evaluate his urinary tract should be:
A. Cystoscopy
B. Cystography
C. Intravenous pyelography (IVP)
D. Retrograde urethrography
Answer: D
Rationale: Blood at the urethral meatus raises suspicion of urethral injury. A
retrograde urethrogram is essential before any attempt at catheterization to
avoid worsening a partial tear.

7) Neurogenic shock classically has all of the following features EXCEPT:
A. Hypotension
B. Vasodilation
C. Bradycardia
D. Narrowed pulse pressure
Answer: D
Rationale: In neurogenic shock (typically with high spinal cord injury), there
is hypotension (due to vasodilation) and often bradycardia. Pulse pressures
tend to be wide rather than narrow because of loss of sympathetic tone.

8) Which of the following statements is FALSE regarding Rh
isoimmunization in pregnant trauma patients?
A. It occurs in blunt or penetrating abdominal trauma.
B. Rh immunoglobulin therapy should be administered to pregnant females
who have sustained a gunshot wound to the leg.
C. This is not a problem in traumatized, Rh-positive pregnant patients.
D. Initiation of Rh immunoglobulin therapy does not require proof of
fetomaternal hemorrhage.
