1) Which of the following signs is LEAST reliable for diagnosing
esophageal intubation?
A. Symmetrical chest wall movement
B. Presence of end-tidal CO₂ by colorimetry
C. Bilateral breath sounds
D. Endotracheal tube (ETT) tip above the carina on chest x-ray
Correct Answer: D
Rationale: Although a chest x-ray confirms tube position after
,intubation, it is less reliable in the immediate setting to rule out
esophageal placement. Real-time indicators (e.g., end-tidal CO₂ and
bilateral breath sounds) are more sensitive.

2) Which of the following findings necessitates a definitive airway in a
severely injured trauma patient?
A. Repeated vomiting
B. Severe maxillofacial fractures
C. Sternal fracture
D. Glasgow Coma Scale of 12
Correct Answer: B
Rationale: Severe maxillofacial fractures threaten airway patency;
securing a definitive airway (e.g., endotracheal tube or surgical
airway) is paramount.

3) Twenty-seven patients are seriously injured in an aircraft crash.
Which principle of mass-casualty triage is MOST appropriate?
A. Establish a triage site within the internal perimeter of the crash site
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
Correct Answer: D
, Rationale: In mass-casualty triage, the goal is to allocate resources so
as to maximize the overall number of survivors, rather than focusing
solely on the most severely injured at the start.

5) Which of the following statements regarding intracranial bleeding
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
Correct Answer: A
Rationale: Cerebral contusions can enlarge over time and become
intracerebral hematomas. Subdurals typically involve bridging veins
and appear crescent-shaped, whereas epidurals are usually biconvex
and often involve the middle meningeal artery.

7) An 18-year-old man presents with a gunshot wound just below the
right clavicle and another at the right costal margin posteriorly. After
airway management and placing two large-bore IV lines, the NEXT
appropriate step is to:
A. Obtain a portable chest x-ray
