ATLS (Advanced Trauma Life Support) 10th Edition Post-Test
Questions and Answers Latest
Question 1: A 35-year-old male is brought to the trauma bay after a high-speed MVC. He is
unconscious, has gurgling respirations, and blood in his oropharynx. His cervical spine is
immobilized. What is the NEXT most appropriate step in management?
A. Obtain a STAT cervical spine CT scan
B. Perform rapid sequence intubation with in-line cervical stabilization
C. Insert a nasogastric tube to decompress the stomach
D. Apply bilateral chest tubes for suspected hemothorax
CORRECT ANSWER: B. Perform rapid sequence intubation with in-line cervical stabilization
Rationale: Per ATLS primary survey (ABCDE), airway with cervical spine protection is the first
priority. An unconscious patient with gurgling respirations and blood in the oropharynx has a
compromised airway requiring immediate definitive control. Rapid sequence intubation with in-
line cervical stabilization secures the airway while maintaining spinal precautions. Obtaining
imaging (A) or placing chest tubes (D) occurs after the airway is secured. Nasogastric tube
placement (C) is contraindicated before airway control due to aspiration risk.
Question 2: During the primary survey of a trauma patient, you note absent breath sounds on
the right, tracheal deviation to the left, and hypotension. What is the IMMEDIATE life-saving
intervention?
A. Obtain a chest X-ray to confirm diagnosis
B. Perform needle decompression of the right hemithorax at the 2nd intercostal space,
midclavicular line
C. Administer 2 liters of crystalloid bolus
D. Prepare for emergency department thoracotomy
CORRECT ANSWER: B. Perform needle decompression of the right hemithorax at the 2nd
intercostal space, midclavicular line
Rationale: This presentation is classic for tension pneumothorax—a clinical diagnosis requiring
immediate intervention without imaging. Needle decompression at the 2nd ICS, MCL is the
ATLS-recommended immediate treatment to relieve mediastinal compression and restore
venous return. Waiting for CXR (A) delays life-saving care. Fluid resuscitation (C) is important but
will not resolve the tension physiology. ED thoracotomy (D) is reserved for traumatic arrest or
specific indications, not initial tension pneumothorax management.
,Question 3: A trauma patient has a systolic blood pressure of 70 mmHg, heart rate of 140 bpm,
and is confused. According to ATLS classification, which class of hemorrhagic shock does this
represent?
A. Class I
B. Class II
C. Class III
D. Class IV
CORRECT ANSWER: C. Class III
Rationale: ATLS classifies hemorrhagic shock by physiologic parameters. Class III shock (30-40%
blood loss) presents with SBP 70-90 mmHg, HR >120 bpm, RR 30-40, decreased urine output,
and altered mental status (confusion/anxiety). Class I (A) has minimal symptoms. Class II (B) has
SBP normal, HR 100-120, mild anxiety. Class IV (D) has SBP <70, HR >140, markedly decreased
LOC.
Question 4: A 28-year-old female with a gunshot wound to the abdomen arrives hypotensive.
After initiating the primary survey and securing the airway, what is the NEXT priority?
A. Obtain FAST exam to identify free fluid
B. Control external hemorrhage and initiate massive transfusion protocol
C. Perform diagnostic peritoneal lavage
D. Obtain CT scan of the abdomen and pelvis
CORRECT ANSWER: B. Control external hemorrhage and initiate massive transfusion protocol
Rationale: Per ATLS circulation phase, after airway, the next priorities are hemorrhage control
and resuscitation. External hemorrhage should be controlled immediately, and for a
hypotensive patient with penetrating torso trauma, activating massive transfusion protocol
(balanced blood product resuscitation) is critical. FAST exam (A) may be performed concurrently
but does not replace hemorrhage control. DPL (C) and CT scan (D) are diagnostic tools that
should not delay resuscitation in an unstable patient.
Question 5: Which finding is MOST indicative of a basilar skull fracture?
A. Scalp laceration over the occiput
B. Periorbital ecchymosis (raccoon eyes) or mastoid ecchymosis (Battle sign)
,C. Linear skull fracture on X-ray
D. Isolated loss of consciousness
CORRECT ANSWER: B. Periorbital ecchymosis (raccoon eyes) or mastoid ecchymosis (Battle sign)
Rationale: Basilar skull fractures classically present with periorbital ecchymosis (raccoon eyes),
mastoid ecchymosis (Battle sign), CSF rhinorrhea/otorrhea, or hemotympanum. These findings
suggest fracture of the skull base. Scalp lacerations (A) and linear fractures (C) may occur with
any skull injury. Isolated LOC (D) is nonspecific.
Question 6: A trauma patient has a GCS of 6, unequal pupils, and is hypotensive. What is the
MOST appropriate initial imaging study?
A. Cervical spine X-rays
B. CT scan of the head
C. FAST exam
D. Whole-body CT (pan-scan)
CORRECT ANSWER: B. CT scan of the head
Rationale: In a patient with altered mental status (GCS ≤8) and signs of possible intracranial
injury (unequal pupils), ATLS prioritizes rapid identification of surgically treatable intracranial
lesions. Non-contrast head CT is the study of choice. While cervical spine imaging (A) and FAST
(C) are important, neurologic deterioration takes precedence. Pan-scan (D) may be appropriate
in stable patients but should not delay emergent head CT in an unstable neurologic patient.
Question 7: During resuscitation of a trauma patient, you note distended neck veins, muffled
heart sounds, and hypotension. What is the MOST likely diagnosis?
A. Tension pneumothorax
B. Cardiac tamponade
C. Massive hemothorax
D. Neurogenic shock
CORRECT ANSWER: B. Cardiac tamponade
Rationale: Beck's triad (hypotension, JVD, muffled heart sounds) is classic for cardiac
tamponade, often from penetrating cardiac injury. Tension pneumothorax (A) also causes
hypotension and JVD but typically has absent breath sounds and tracheal deviation. Massive
hemothorax (C) causes hypotension and decreased breath sounds but not muffled heart
, sounds. Neurogenic shock (D) causes hypotension with bradycardia and warm extremities, not
JVD.
Question 8: What is the INITIAL management of a patient with an open (sucking) chest wound?
A. Apply an occlusive dressing taped on three sides
B. Immediately insert a chest tube
C. Perform needle decompression
D. Administer high-flow oxygen only
CORRECT ANSWER: A. Apply an occlusive dressing taped on three sides
Rationale: An open pneumothorax ("sucking chest wound") allows air to enter the pleural space
during inspiration, impairing ventilation. ATLS recommends covering the wound with an
occlusive dressing taped on three sides to create a one-way valve—allowing air to escape during
expiration but preventing entry during inspiration. Chest tube insertion (B) is definitive
management but follows initial wound coverage. Needle decompression (C) is for tension
pneumothorax. Oxygen (D) is supportive but does not address the underlying pathophysiology.
Question 9: A pediatric trauma patient (age 4) has a heart rate of 180 bpm, delayed capillary
refill, and is lethargic. Which finding is MOST concerning for decompensated shock?
A. Tachycardia alone
B. Hypotension
C. Delayed capillary refill
D. Lethargy/altered mental status
CORRECT ANSWER: B. Hypotension
Rationale: In pediatric trauma, hypotension is a LATE and ominous sign of decompensated
shock. Children compensate well with tachycardia and peripheral vasoconstriction; by the time
BP drops, they are near cardiovascular collapse. While tachycardia (A), delayed capillary refill
(C), and lethargy (D) indicate shock, hypotension signifies imminent arrest and requires
immediate aggressive intervention.
Question 10: What is the MOST appropriate initial fluid resuscitation for a trauma patient in
hemorrhagic shock?
