Question 1
A 28-year-old male arrives after a high-speed MVC. He is
unconscious, with noisy breathing and visible chest bruising.
What is your first action?
A) Jaw thrust with cervical spine immobilization
B) Endotracheal intubation
C) Apply cricoid pressure
D) Logroll patient
,Page 2 of 178
Correct Answer: A
Rationale: Airway is the first step of primary survey. Jaw
thrust maintains airway without moving the c-spine. Scenario:
Unconscious patient → assume c-spine injury → protect
airway via jaw thrust.
Question 2
Which findings indicate an obstructed airway? (Select all that
apply)
A) Stridor
B) Hoarseness
C) Absent breath sounds D)
Symmetric chest rise
Correct Answers: A, B, C
Rationale: Stridor (upper airway obstruction), hoarseness
(laryngeal injury), absent breath sounds (complete obstruction).
Symmetric chest rise suggests patent airway.
Question 3
,Page 3 of 178
A 45-year-old female has tachypnea, tracheal deviation to
the right, and absent breath sounds on the left after a stab
wound. What is the immediate intervention?
A) Chest tube insertion
B) Needle decompression at 2nd intercostal space,
midclavicular line
C) Endotracheal intubation
D) Chest x-ray
Correct Answer: B
Rationale: Tension pneumothorax – life-threatening. Needle
decompression before imaging.
Scenario: Trauma arrest or impending arrest → immediate
decompression.
Question 4
During the primary survey, which finding would most likely
require immediate chest decompression?
A) Subcutaneous emphysema
, Page 4 of 178
B) Unilateral breath sounds with hypotension
C) Rib fractures on palpation
D) Oxygen saturation 92%
Correct Answer: B
Rationale: Unilateral breath sounds + hypotension = tension
pneumothorax until proven otherwise.
Question 5
A patient with a GCS of 14, tachypnea, and oxygen
saturation of 89% on room air. After high-flow O2, saturations
remain 90%. Next step? A) Intubate
B) Obtain chest x-ray
C) Apply non-rebreather mask
D) Consider needle decompression if clinical signs present
Correct Answer: D
Rationale: Hypoxia despite high-flow O2 suggests a
mechanical problem (pneumothorax, hemothorax, contusion).
Assess breathing again.
