1. A 27-year-old motorcyclist is brought to the trauma bay after a
high-speed collision. He is confused, has facial bleeding, and is
making gurgling sounds. What is the most appropriate immediate
priority?
A. Obtain a lateral cervical spine radiograph
B. Establish two large-bore peripheral IVs
C. Assess and secure the airway while maintaining cervical spine
protection
D. Perform a focused abdominal ultrasound
Answer: C. Assess and secure the airway while maintaining cervical
spine protection
Rationale: In the initial trauma assessment, airway management takes
priority because airway obstruction can rapidly cause hypoxia and
death. Facial trauma, blood, vomitus, and altered mental status
increase the risk of airway compromise. The cervical spine should be
protected while the airway is assessed and managed. Diagnostic
imaging and vascular access are important but should not delay
treatment of an immediately threatened airway.
2. During the primary survey of a trauma patient, the patient suddenly
develops severe respiratory distress, hypotension, distended neck
, veins, and absent breath sounds on the right side. What diagnosis
should be suspected?
A. Massive hemothorax
B. Tension pneumothorax
C. Cardiac tamponade
D. Pulmonary contusion
Answer: B. Tension pneumothorax
Rationale: The combination of respiratory distress, hypotension,
unilateral absent breath sounds, and distended neck veins strongly
suggests tension pneumothorax. It is an immediately life-threatening
condition caused by pressure accumulation within the pleural space
that compromises venous return and ventilation. Treatment should not
be delayed for imaging when the clinical diagnosis is clear.
3. A trauma patient has a Glasgow Coma Scale score of 7 and is
unable to protect his airway. Which intervention is most
appropriate?
A. Place the patient in a lateral recovery position
B. Administer oral oxygen
C. Perform a nasopharyngeal airway insertion
D. Perform definitive airway management with cervical spine
protection
Answer: D. Perform definitive airway management with cervical spine
protection
Rationale: A severely depressed level of consciousness with a GCS of 8
or less generally indicates an inability to reliably protect the airway.
Definitive airway management is therefore indicated. Cervical spine
,precautions should be maintained because significant trauma may
have caused an unstable cervical injury.
4. A trauma patient has severe maxillofacial trauma, active oral
bleeding, and rapidly increasing airway obstruction. Orotracheal
intubation is unsuccessful. What is the next appropriate
consideration?
A. Emergency surgical airway
B. Delay airway intervention until CT imaging
C. Blind nasotracheal intubation
D. Observe the patient closely
Answer: A. Emergency surgical airway
Rationale: When a trauma patient's airway cannot be secured by
conventional methods and oxygenation or ventilation cannot be
maintained, an emergency surgical airway may be required. Severe
facial trauma and oral bleeding can make conventional airway
management particularly difficult. Delaying definitive airway control
in a deteriorating patient can result in hypoxic arrest.
5. A trauma patient has a penetrating chest injury and severe
respiratory distress. Examination reveals absent breath sounds on
the left and dullness to percussion. Which condition is most likely?
A. Simple pneumothorax
B. Flail chest
C. Massive hemothorax
D. Cardiac tamponade
Answer: C. Massive hemothorax
Rationale: Massive hemothorax typically produces respiratory
compromise, decreased or absent breath sounds, and dullness to
, percussion because blood occupies the pleural space. It can also
produce shock through substantial blood loss and impaired venous
return. Immediate resuscitation and chest drainage are central
components of management, with operative intervention considered
when bleeding is severe or persistent.
6. A patient with blunt chest trauma has paradoxical movement of a
segment of the chest wall during inspiration and expiration. What
injury is most consistent with this finding?
A. Pulmonary contusion
B. Flail chest
C. Simple rib fracture
D. Open pneumothorax
Answer: B. Flail chest
Rationale: Flail chest occurs when a segment of the thoracic cage
becomes mechanically detached because of multiple rib fractures,
generally involving several ribs in multiple locations. The unstable
segment may move paradoxically during respiration. Respiratory
compromise may be worsened by associated pulmonary contusion,
pain, and inadequate ventilation.
7. A trauma patient has a chest wound that produces a sucking sound
with each inspiration. What is the immediate treatment?
A. Apply an appropriate occlusive dressing and address the pleural
injury
B. Remove all dressings and allow unrestricted air entry
C. Perform abdominal decompression
D. Administer oral fluids
