1. A trauma patient arrives after a high-speed motor vehicle collision. During the
initial assessment, which finding requires the most immediate intervention?
A. Open femur fracture with moderate bleeding
B. Airway obstruction with inadequate ventilation
C. Abdominal tenderness without hypotension
D. Closed forearm fracture with deformity
Rationale: Airway and breathing problems can cause rapid death and therefore take priority
during the primary survey. Significant orthopedic and abdominal findings must be addressed,
but they do not supersede an immediately compromised airway and ventilation.
2. During the primary survey of an injured patient, which sequence correctly reflects
the major priorities?
A. Disability, exposure, circulation, airway, breathing
B. Circulation, airway, disability, breathing, exposure
C. Airway, circulation, disability, exposure, breathing
D. Airway, breathing, circulation, disability, exposure
Rationale: The primary survey follows the ABCDE approach: airway with cervical spine
protection, breathing and ventilation, circulation with hemorrhage control, disability
assessment, and exposure/environmental control.
3. A trauma patient is speaking clearly in complete sentences immediately after
arrival. What does this finding most strongly suggest?
A. The airway is currently patent
B. The cervical spine is definitely uninjured
C. There is no significant thoracic injury
D. The patient has adequate circulating volume
,Rationale: Clear speech indicates that air is moving through the upper airway sufficiently at that
moment. It does not exclude cervical spine injury, thoracic trauma, or shock.
4. A patient with facial trauma has blood and secretions obstructing the mouth.
What is the most appropriate initial action to improve the airway?
A. Perform a chest tube insertion
B. Administer a sedative
C. Suction the airway while maintaining appropriate spinal precautions
D. Immediately place the patient in a seated position
Rationale: Blood and secretions can rapidly compromise the airway. Suctioning removes the
obstruction while spinal precautions are maintained because significant facial trauma may
coexist with cervical spine injury.
5. Which clinical finding is most concerning for an impending upper-airway
obstruction in a trauma patient?
A. Mild tachycardia
B. Superficial scalp abrasion
C. Isolated wrist tenderness
D. Stridor with increasing respiratory distress
Rationale: Stridor indicates significant upper-airway narrowing and may precede complete
obstruction. Progressive respiratory distress makes urgent airway management particularly
important.
6. A trauma patient has suspected cervical spine injury and requires airway support.
Which principle should guide airway management?
A. Remove all spinal precautions before attempting airway management
B. Maintain cervical spine protection while securing the airway
C. Delay airway intervention until cervical radiographs are completed
D. Avoid suctioning because it can cause cervical movement
Rationale: Airway management takes priority, but unnecessary cervical movement should be
minimized. Cervical spine protection should be maintained while the airway is secured.
, 7. A patient with severe facial trauma cannot maintain an adequate airway and has
persistent hypoxemia despite initial measures. Which intervention is most
appropriate?
A. Observe the patient for another 30 minutes
B. Treat only the facial wounds initially
C. Establish a definitive airway
D. Give oral fluids to improve circulation
Rationale: Failure to maintain airway patency or adequate oxygenation despite initial measures
is an indication for definitive airway management. Observation or oral intake is inappropriate in
a patient with severe airway compromise.
8. Following blunt chest trauma, a patient develops severe respiratory distress,
hypotension, distended neck veins, and markedly decreased breath sounds on
one side. Which condition should be suspected?
A. Simple rib fracture
B. Pulmonary contusion
C. Cardiac tamponade
D. Tension pneumothorax
Rationale: The combination of respiratory distress, hypotension, unilateral decreased breath
sounds, and signs of obstructive physiology strongly suggests tension pneumothorax. Immediate
decompression should not be delayed for definitive imaging when the diagnosis is clinically
evident.
9. A trauma patient has an open chest wound with air moving through the wound
during inspiration. What is the initial treatment?
A. Apply an appropriate occlusive dressing and assess ventilation
B. Pack the wound deeply with gauze
C. Close the wound permanently with sutures immediately
D. Place the patient flat without treating the wound
, Rationale: An open chest wound can produce an open pneumothorax and impair ventilation. An
appropriate occlusive dressing helps limit air entry while the patient is assessed and definitive
management is arranged.
10. A patient with multiple rib fractures has increasing work of breathing and
worsening oxygenation. Which associated injury should be considered
particularly important?
A. Isolated clavicle fracture
B. Pulmonary contusion
C. Distal radius fracture
D. Superficial abdominal abrasion
Rationale: Significant blunt chest trauma and rib fractures may be accompanied by pulmonary
contusion, which can impair gas exchange and may worsen over time.
11. A trauma patient suddenly becomes hypotensive after a penetrating chest injury.
Heart sounds are muffled and neck veins are distended. Which diagnosis is most
likely?
A. Massive hemothorax
B. Tension pneumothorax
C. Cardiac tamponade
D. Simple pneumothorax
Rationale: Hypotension, muffled heart sounds, and venous distention are classic findings
associated with cardiac tamponade. In trauma, rapid recognition and appropriate intervention
are critical.
12. A patient with major chest trauma has severe respiratory distress and dullness to
percussion over one side of the chest. Which condition is most consistent with
these findings?
A. Simple pneumothorax
B. Cardiac tamponade
C. Pulmonary embolism
D. Massive hemothorax
