Introduction
The Advanced Trauma Life Support assessment is designed to evaluate a clinician’s proficiency in the systematic identification, prioritization, and
management of life-threatening injuries in acute trauma settings. Assessing both foundational medical theory and critical decision-making under
duress, this exam utilizes complex, scenario-based multiple-choice questions to mirror real-world clinical environments. Candidates must
demonstrate an advanced understanding of standard trauma algorithms, diagnostic interpretation, and professional ethics. Success requires the
application of precise, time-sensitive interventions within the golden hour to optimize patient outcomes, establishing a standardized baseline of
competence for healthcare professionals managing multi-system trauma.
Section One: Questions 1–100
Question 1
A 34-year-old male is brought to the emergency department following a high-speed motor vehicle collision. He is cyanotic, tachycardic, and
demonstrating severe respiratory distress. Inspection reveals asymmetric chest expansion with absent breath sounds on the left side, along with
jugular venous distention. What is the immediate next step in management?
A. Obtain a portable anteroposterior chest X-ray
B. Perform an endotracheal intubation
🟢 C. Perform needle decompression in the fifth intercostal space, anterior to the midaxillary line
D. Insert a large-bore chest tube into the left pleural space
,🔴 RATIONALE: The clinical presentation of respiratory distress, asymmetric chest expansion, absent breath sounds, and jugular venous distention
indicates a tension pneumothorax. This is a clinical diagnosis that requires immediate needle decompression before obtaining imaging, as delaying
treatment can lead to cardiovascular collapse.
Question 2
A 45-year-old female pedestrian is struck by a vehicle and sustains multiple injuries. On arrival, her blood pressure is 82/44 mmHg, heart rate is 132
bpm, and respiratory rate is 28 breaths/min. She is awake but confused. What class of hemorrhagic shock is this patient exhibiting?
A. Class I
B. Class II
🟢 C. Class III
D. Class IV
🔴 RATIONALE: Class III hemorrhagic shock is characterized by significant tachycardia (heart rate greater than 120 bpm), hypotension (decreased
systolic blood pressure), tachypnea, and altered mental status such as confusion or anxiety, representing an approximate 15% to 30% blood volume
loss.
Question 3
A 22-year-old male suffers a penetrating stab wound to the left mid-clavicular fourth intercostal space. On assessment, his blood pressure is 90/60
mmHg, heart rate is 120 bpm, and breath sounds are equal bilaterally. Jugular venous distention is noted, and heart sounds appear muffled. Which
diagnostic modality is best suited to rapidly confirm the suspected pathology?
A. Chest computed tomography (CT) scan
B. Electrocardiogram (ECG)
🟢 C. Focused Assessment with Sonography for Trauma (FAST)
D. Diagnostic peritoneal lavage (DPL)
🔴 RATIONALE: The triad of hypotension, jugular venous distention, and muffled heart sounds constitutes Beck's triad, which indicates cardiac
tamponade. A FAST exam can rapidly visualize pericardial fluid at the bedside to confirm this diagnosis in an unstable trauma patient.
Question 4
During the primary survey of an unconscious trauma patient who fell from a height of 20 feet, which maneuver should be utilized to open the airway
while maintaining cervical spine stabilization?
🟢 A. Jaw-thrust maneuver
B. Head-tilt/chin-lift maneuver
C. Extreme hyperextension of the neck
D. Lateral recovery positioning
,🔴 RATIONALE: The jaw-thrust maneuver is the preferred method for opening the airway in a trauma patient with a suspected cervical spine injury
because it minimizes neck movement, unlike the head-tilt/chin-lift maneuver which extends the cervical spine.
Question 5
A 68-year-old male on chronic warfarin therapy for atrial fibrillation slips and hits his head on a concrete sidewalk. His initial Glasgow Coma Scale
(GCS) score is 14. Within an hour, his GCS drops to 9, and his right pupil becomes dilated and sluggishly reactive. Which intracranial pathology is
most consistent with this presentation?
A. Epidural hematoma
🟢 B. Subdural hematoma
C. Subarachnoid hemorrhage
D. Diffuse axonal injury
🔴 RATIONALE: Subdural hematomas result from the tearing of bridging veins and are more common in elderly individuals and patients on
anticoagulation therapy. The progressive decline in neurological status and pupillary changes indicate an expanding mass lesion compressing the
brainstem.
Question 6
A 29-year-old pregnant female at 32 weeks gestation is involved in a head-on motor vehicle collision. She is secured on a backboard. Her blood
pressure is 94/56 mmHg and heart rate is 105 bpm. What positioning adjustment should be made immediately to improve maternal hemodynamics?
A. Elevate the head of the bed to 45 degrees
B. Place the patient in a Trendelenburg position
🟢 C. Tilt the backboard 15 to 30 degrees to the left
D. Maintain a strictly flat, supine position
🔴 RATIONALE: In advanced pregnancy, the gravid uterus compresses the inferior vena cava when the patient is in the supine position, decreasing
venous return and causing supine hypotensive syndrome. Tilting the patient or displacing the uterus to the left relieves this compression.
Question 7
A 19-year-old male is admitted to the trauma bay following an explosion. He has sustained deep partial-thickness and full-thickness burns covering
his entire anterior torso and both anterior lower extremities. Using the Rule of Nines, what is the estimated total body surface area (TBSA) burned?
A. 27%
🟢 B. 36%
C. 45%
D. 54%
🔴 RATIONALE: According to the Rule of Nines, the anterior torso accounts for 18% of the TBSA, and each anterior lower extremity accounts for 9%
(18% for both). Summing these regions yields 18% + 18% = 36% TBSA.
, Question 8
A 50-year-old male is brought to the emergency department after falling 15 feet from a ladder. He complains of severe back pain. Assessment
reveals loss of motor function and sensation to pain and temperature in both lower extremities, but proprioception and vibration sensation are
preserved. What spinal cord syndrome is described?
🟢 A. Anterior cord syndrome
B. Brown-Séquard syndrome
C. Central cord syndrome
D. Cauda equina syndrome
🔴 RATIONALE: Anterior cord syndrome typically results from ischemia or infarction of the anterior spinal artery or bone fragments fragments
compressing the anterior cord. It spares the dorsal columns, thereby preserving proprioception and vibration sensation while losing motor and
spinothalamic functions.
Question 9
Which of the following findings mandates an immediate operative intervention during the initial evaluation of a blunt abdominal trauma patient,
bypassing further diagnostic imaging like a CT scan?
A. Microscopic hematuria
B. Single rib fracture with localized tenderness
🟢 C. Hemodynamic instability with a positive FAST exam
D. Isolated pelvic fracture on X-ray
🔴 RATIONALE: A patient with blunt abdominal trauma who is hemodynamically unstable and has a positive FAST exam demonstrating free intra-
abdominal fluid requires an immediate exploratory laparotomy to control hemorrhage.
Question 10
A 41-year-old male presents with an open femur fracture following a motorcycle crash. The wound is heavily contaminated with dirt and debris. What
is the legal and clinical standard regarding tetanus prophylaxis in an individual with unknown immunization history?
A. Administer tetanus toxoid only
B. Administer tetanus immune globulin only
🟢 C. Administer both tetanus toxoid and tetanus immune globulin
D. Defer tetanus prophylaxis until the immunization status is confirmed by family
🔴 RATIONALE: For clean wounds in individuals with an unknown or incomplete tetanus immunization history, tetanus toxoid is sufficient. However,
for contaminated or deep wounds, both tetanus toxoid and tetanus immune globulin (TIG) are required to provide immediate passive immunity
alongside active immunization.
