Domain 1: Initial Assessment & Primary Survey (ABCDE) (20 Questions)
Q1: A 34-year-old unrestrained driver is ejected after high-speed rollover. On arrival: GCS
3T, HR 148, BP 74/40, absent breath sounds left, trachea midline. FAST positive in
Morrison's pouch. What is the NEXT immediate intervention according to ATLS
priorities?
A. Insert bilateral chest tubes
B. Perform endotracheal intubation
C. Initiate massive transfusion protocol
D. Perform left needle decompression in 2nd intercostal space, midclavicular line
[CORRECT]
Correct Answer: D
Rationale: This patient presents with the lethal triad of trauma: hypotension (SBP 74),
tachycardia (HR 148), and altered mental status (GCS 3). The combination of absent left
breath sounds with hemodynamic instability indicates a tension pneumothorax until
proven otherwise, despite the trachea being midline (which can occur in early stages or
with bilateral pathology). According to ATLS 10th Edition Primary Survey priorities,
,life-threatening conditions are addressed immediately upon identification without
waiting for imaging confirmation.
● Option A (Chest tubes) is incorrect because needle decompression must precede
tube thoracostomy in suspected tension pneumothorax with hemodynamic
compromise. Chest tube insertion takes longer and delays immediate
decompression.
● Option B (Intubation) is incorrect because while the GCS 3 mandates airway
protection, the tension pneumothorax represents an immediate threat to life that
will cause rapid cardiovascular collapse if not addressed first. Additionally,
positive pressure ventilation without decompression can worsen the tension
pneumothorax.
● Option C (MTP) is premature; while the patient will likely need massive
transfusion for the positive FAST, the immediate life threat is the tension
pneumothorax causing obstructive shock.
The correct sequence follows the ABCDE approach: Airway with cervical spine
protection (while preparing for intubation), but immediately address Breathing
threats—specifically tension pneumothorax requiring immediate needle decompression
at the 2nd intercostal space, midclavicular line (5th intercostal space, anterior axillary
line is an acceptable alternative per ATLS 10th Edition updates).
Q2: A 28-year-old motorcyclist strikes a tree at high speed. Primary survey reveals:
patent airway, RR 32, SpO2 88% on room air, diminished breath sounds bilaterally with
contusions over chest wall. HR 118, BP 96/60. GCS 14. What is the NEXT appropriate
step?
A. Immediate endotracheal intubation
B. Apply supplemental high-flow oxygen and assess for tension pneumothorax
[CORRECT]
C. Perform bilateral needle decompressions prophylactically
D. Obtain chest X-ray before any intervention
,Correct Answer: B
Rationale: The patient demonstrates respiratory distress (RR 32, SpO2 88%) with
bilateral chest wall contusions suggesting pulmonary contusion and/or flail chest.
According to ATLS protocols, all trauma patients receive supplemental oxygen
immediately to prevent hypoxemia-induced secondary brain injury and maintain tissue
oxygenation.
● Option A (Intubation) is premature; while the patient may eventually require
intubation for respiratory failure, immediate interventions include oxygenation,
ventilation assessment, and exclusion of immediately life-threatening conditions
like tension pneumothorax.
● Option C (Bilateral needle decompression) is incorrect without definitive signs of
tension pneumothorax (hypotension, tracheal deviation, JVD, unilateral absent
breath sounds). Needle decompression carries risks including vascular injury and
should not be performed prophylactically.
● Option D (Chest X-ray first) violates ATLS principles—life-threatening conditions
are treated based on clinical suspicion before radiographic confirmation.
The correct approach applies the Breathing component of the primary survey: high-flow
oxygen administration, visual inspection, auscultation, and palpation for crepitus,
followed by targeted intervention based on findings.
Q3: During the primary survey of a 45-year-old pedestrian struck by a vehicle, you note:
GCS 15, patent airway, equal breath sounds, HR 132, BP 82/50, cool extremities, delayed
capillary refill. What is the MOST likely classification of shock and immediate
management?
A. Neurogenic shock; administer dopamine
B. Hemorrhagic shock; initiate balanced crystalloid resuscitation and locate source of
bleeding [CORRECT]
C. Cardiogenic shock; perform bedside echocardiogram
, D. Septic shock; administer broad-spectrum antibiotics
Correct Answer: B
Rationale: This patient presents with Class III hemorrhagic shock (blood loss 30-40%,
HR >120, SBP decreased, altered mentation typically present in Class III-IV). The
mechanism (pedestrian vs. vehicle) suggests high-energy trauma with potential for
multiple bleeding sources. The clinical picture—tachycardia with hypotension, cool
clammy skin, and delayed capillary refill—is classic for hemorrhagic hypovolemic shock.
● Option A (Neurogenic shock) is incorrect because neurogenic shock presents
with warm, dry skin due to loss of sympathetic tone and vasodilation, not cool
extremities. Additionally, neurogenic shock typically shows bradycardia or normal
heart rate despite hypotension.
● Option C (Cardiogenic shock) is unlikely in this young trauma patient without
cardiac history; while cardiac tamponade or myocardial contusion should be
considered, the peripheral vasoconstriction (cool skin) indicates compensatory
mechanisms consistent with hypovolemia.
● Option D (Septic shock) is temporally impossible in acute trauma and presents
with warm shock (vasodilation) rather than cold shock.
Per ATLS 10th Edition, hemorrhage control takes precedence over fluid resuscitation
when source control is achievable. Immediate management includes two large-bore IV
lines, type and crossmatch, initial 1-2L warmed balanced crystalloid (Lactated Ringer's
preferred), and immediate diagnostic workup (FAST, chest/pelvis X-ray) to identify
bleeding sources while preparing for blood products.
Q4: A 52-year-old restrained driver in a frontal collision complains of chest pain. Primary
survey: patent airway, RR 28, SpO2 92% on 15L O2, HR 110, BP 140/90. Chest
examination reveals paradoxical movement of the left lower lateral chest wall. What is
the NEXT step in management?
