ATLS 11 Head & Spine Trauma Study Guide |
Practice Questions, Answers & Detailed
Rationales | Exam Prep 2026/2027
Question 1: Which finding is the most sensitive indicator of early
neuroworsening in a patient with severe traumatic brain injury?
A. Anisocoria
B. Change in Glasgow Coma Scale score
C. Hypertension
D. Bradycardia
CORRECT ANSWER: B. Change in Glasgow Coma Scale score
Rationale: Neuroworsening is defined as a deterioration in neurological
status, most commonly detected by a decline in the Glasgow Coma Scale
(GCS) score. While pupillary changes and Cushing's triad (hypertension
and bradycardia) are critical signs, they often appear later. Serial GCS
monitoring remains the most sensitive and earliest clinical indicator of
secondary brain injury, guiding the need for immediate intervention and
imaging .
Question 2: What is the recommended minimum systolic blood
pressure target for an adult patient with severe traumatic brain injury
according to ATLS 11th Edition principles?
A. 70 mmHg
B. 80 mmHg
C. 90 mmHg
D. 110 mmHg
CORRECT ANSWER: D. 110 mmHg
Rationale: The ATLS 11th Edition emphasizes strict neuroprotective targets.
For adults with severe TBI, maintaining a systolic blood pressure of at least
110 mmHg is recommended to ensure adequate cerebral perfusion
pressure and prevent secondary ischemic injury. A single episode of
hypotension (SBP < 90 mmHg) significantly increases morbidity and
mortality .
Question 3: A patient with a suspected cervical spine injury requires
emergent intubation due to apnea. Which technique is most
appropriate to minimize spinal movement?
,A. Direct laryngoscopy with cricoid pressure
B. Manual in-line stabilization with video laryngoscopy
C. Blind nasotracheal intubation
D. Orotracheal intubation with full neck extension
CORRECT ANSWER: B. Manual in-line stabilization with video
laryngoscopy
Rationale: In patients with suspected cervical spine injury requiring airway
management, manual in-line stabilization (MILS) must be maintained to
prevent excessive neck movement. Video laryngoscopy is preferred as it
often requires less cervical spine manipulation than direct laryngoscopy
and provides better visualization, reducing the risk of secondary spinal
cord injury during intubation .
Question 4: Which clinical sign is most characteristic of neurogenic
shock in a patient with a complete cervical spinal cord injury?
A. Tachycardia and cool extremities
B. Hypotension and bradycardia
C. Hypertension and widened pulse pressure
D. Narrow pulse pressure and delayed capillary refill
CORRECT ANSWER: B. Hypotension and bradycardia
Rationale: Neurogenic shock results from the loss of sympathetic outflow
following a high spinal cord injury (typically above T6). This leads to
vasodilation (hypotension) and unopposed vagal tone (bradycardia). This
distinguishes it from hemorrhagic shock, which typically presents with
tachycardia and cool, clammy skin .
Question 5: Which of the following findings most strongly suggests a
basilar skull fracture in a trauma patient?
A. Scalp laceration over the occiput
B. Bilateral periorbital ecchymosis (Raccoon eyes)
C. Unilateral fixed dilated pupil
D. Battle's sign (postauricular ecchymosis) and CSF otorrhea
CORRECT ANSWER: D. Battle's sign (postauricular ecchymosis) and
CSF otorrhea
,Rationale: Basilar skull fractures are often indicated by specific clinical
signs including hemotympanum, cerebrospinal fluid (CSF) rhinorrhea or
otorrhea, periorbital ecchymosis, and retroauricular ecchymosis (Battle's
sign). These signs indicate a fracture at the base of the skull and carry a
high risk of associated cranial nerve injury and infection .
Question 6: In the ATLS 11th Edition, what is the recommended
approach for spinal motion restriction in a patient with isolated
penetrating trauma to the abdomen and no neurological deficit?
A. Full spinal immobilization with a rigid collar and backboard
B. Spinal motion restriction is not indicated
C. Cervical collar only
D. Log-roll the patient onto a vacuum mattress
CORRECT ANSWER: B. Spinal motion restriction is not indicated
Rationale: The ATLS 11th Edition supports a selective, criteria-based
approach to spinal motion restriction. For patients with penetrating trauma
and no neurological deficit, routine spinal immobilization is not
recommended. Evidence indicates that the risks of immobilization (e.g.,
delayed transport, difficulty with procedures, pressure sores) outweigh the
benefits in this population .
Question 7: A patient with a severe TBI has a Glasgow Coma Scale
score of 6. What is the most appropriate immediate management for
this patient's airway?
A. Nasopharyngeal airway insertion
B. Oropharyngeal airway insertion
C. Definitive airway (endotracheal intubation)
D. Supplemental oxygen via non-rebreather mask
CORRECT ANSWER: C. Definitive airway (endotracheal intubation)
Rationale: A GCS score of 8 or less is a widely accepted threshold for
definitive airway management. Patients with severe TBI (GCS ≤ 8) cannot
reliably protect their airway, are at high risk for aspiration, and often require
hyperventilation or controlled ventilation. Endotracheal intubation with in-
line stabilization is indicated .
, Question 8: Which imaging modality is the optimal initial investigation
for a hemodynamically stable patient with suspected traumatic brain
injury?
A. Skull radiograph
B. Magnetic resonance imaging (MRI)
C. Non-contrast computed tomography (CT) of the head
D. Carotid duplex ultrasound
CORRECT ANSWER: C. Non-contrast computed tomography (CT) of the
head
Rationale: Non-contrast CT scan of the head is the gold standard and
optimal initial imaging investigation for traumatic brain injury. It rapidly
identifies acute intracranial pathology including epidural hematomas,
subdural hematomas, subarachnoid hemorrhage, and cerebral contusions,
which directly guides neurosurgical decision-making .
Question 9: A trauma patient has a spinal cord injury and presents with
hypotension. After initial fluid resuscitation, the blood pressure
remains low with a heart rate of 52 beats per minute. What is the most
appropriate pharmacologic intervention?
A. Norepinephrine infusion
B. Phenylephrine bolus
C. Atropine administration
D. Dopamine infusion
CORRECT ANSWER: A. Norepinephrine infusion
Rationale: This patient is exhibiting neurogenic shock with hypotension and
bradycardia. After volume resuscitation, vasopressors are required to
restore vascular tone. Norepinephrine is often the first-line agent as it
provides both alpha-adrenergic (vasoconstriction) and some beta-
adrenergic (cardiac support) effects, addressing both the hypotension and
potentially the bradycardia .
Question 10: Which physical examination finding is most reliable for
clearing the cervical spine in an alert, asymptomatic patient according
to the NEXUS criteria?
A. Absence of midline cervical spine tenderness
B. Presence of a distracting injury
