1. A 24-year-old patient involved in a high-speed motor vehicle
collision has a Glasgow Coma Scale (GCS) score of 7. What is the
most appropriate immediate airway intervention?
A. Observe closely while obtaining a head CT
B. Administer oral fluids
C. Perform definitive airway management with cervical spine protection
D. Delay airway management until neurologic consultation
Answer: C. Perform definitive airway management with cervical
spine protection
Rationale: A patient with a GCS of 7 has severe traumatic brain injury
and is unable to reliably protect the airway. Early definitive airway
management is indicated while maintaining cervical spine precautions
because hypoxia and aspiration can worsen secondary brain injury.
2. Which finding is most concerning for impending cerebral
herniation after traumatic brain injury?
A. Mild headache
B. Progressive unilateral fixed and dilated pupil
C. Superficial scalp abrasion
D. Brief nausea without neurologic change
,Answer: B. Progressive unilateral fixed and dilated pupil
Rationale: A newly dilated and poorly reactive unilateral pupil may
indicate third-nerve compression from transtentorial herniation. This
is a neurologic emergency requiring immediate treatment of
intracranial hypertension while definitive evaluation and surgical
management are arranged.
3. Which principle is most important in preventing secondary brain
injury after trauma?
A. Avoid all analgesia
B. Maintain adequate oxygenation and cerebral perfusion
C. Keep the patient hypotensive
D. Delay treatment until imaging is completed
Answer: B. Maintain adequate oxygenation and cerebral perfusion
Rationale: Secondary brain injury is promoted by hypoxia,
hypotension, hypercarbia, severe hypocarbia, fever, seizures, and
increased intracranial pressure. Preventing physiologic deterioration
is therefore a central component of early traumatic brain injury
management.
4. A trauma patient has a GCS score of 13 after a fall. How is the
brain injury generally classified?
A. Mild traumatic brain injury
B. Moderate traumatic brain injury
C. Severe traumatic brain injury
D. Brain death
Answer: A. Mild traumatic brain injury
Rationale: Traumatic brain injury is commonly categorized using
GCS: 13–15 is mild, 9–12 is moderate, and 3–8 is severe. Clinical
,context, imaging, neurologic examination, and associated injuries
must also guide management.
5. Which component is included in the Glasgow Coma Scale?
A. Pupillary diameter
B. Motor response
C. Blood pressure
D. Respiratory rate
Answer: B. Motor response
Rationale: The GCS assesses eye opening, verbal response, and motor
response. The total score ranges from 3 to 15. Motor response is
particularly valuable because it provides important information about
cortical and brainstem function.
6. A patient with severe head trauma has an oxygen saturation of
82%. What should be prioritized?
A. Immediate noncontrast head CT before intervention
B. Correction of hypoxemia
C. Lumbar puncture
D. Oral sedatives
Answer: B. Correction of hypoxemia
Rationale: Hypoxemia causes cerebral hypoxia and can substantially
worsen secondary brain injury. Airway and breathing interventions
take priority during the initial trauma assessment, and oxygenation
should be corrected promptly.
7. Which type of intracranial hemorrhage is classically associated
with an arterial injury and a lens-shaped collection on CT?
, A. Subdural hematoma
B. Epidural hematoma
C. Subarachnoid hemorrhage
D. Intraventricular hemorrhage
Answer: B. Epidural hematoma
Rationale: Epidural hematomas commonly result from arterial
bleeding, classically involving the middle meningeal artery. CT
typically demonstrates a biconvex or lentiform extra-axial collection
that is limited by cranial sutures.
8. Which clinical history is classically associated with an epidural
hematoma?
A. Progressive decline without any trauma
B. Loss of consciousness followed by a lucid interval
C. Isolated chronic memory impairment
D. Immediate bilateral blindness
Answer: B. Loss of consciousness followed by a lucid interval
Rationale: A lucid interval is a classic but not universal feature of
epidural hematoma. The patient may initially recover consciousness
and then deteriorate as arterial bleeding expands the hematoma and
increases intracranial pressure.
9. A subdural hematoma most commonly results from injury to which
structures?
A. Middle meningeal arteries
B. Bridging veins
C. Carotid arteries
D. Dural venous sinuses exclusively
Answer: B. Bridging veins
