PART 1: APPLY THE SYSTEMATIC ABCDE PRIMARY SURVEY TO RAPIDLY IDENTIFY
AND MANAGE LIFE-THREATENING CONDITIONS IN TRAUMA PATIENTS
1. A patient with severe blunt chest trauma exhibits tracheal deviation, absent breath sounds, and hypotension.
Which intervention is the definitive immediate management?
A) Needle decompression at the 2nd intercostal space midclavicular line
B) Tube thoracostomy at the 5th intercostal space anterior axillary line
C) Immediate intubation with positive pressure ventilation
D) Pericardiocentesis via subxiphoid approach
' Correct Answer: B
Rationale: Tube thoracostomy is definitive for tension pneumothorax, providing continuous drainage. Needle
decompression is temporizing. Intubation without decompression can worsen tension. Pericardiocentesis addresses
cardiac tamponade, not pneumothorax.
2. In a patient with suspected cervical spine injury, which of the following findings best indicates the need for
immediate immobilization and imaging?
A) Midline cervical tenderness and limited range of motion
B) Presence of a distracting injury
C) Glasgow Coma Scale score of 15
D) No neurologic deficits on examination
' Correct Answer: A
Rationale: Midline tenderness and limited range of motion are high-risk criteria for cervical spine injury per
NEXUS and Canadian C-Spine Rules. Distracting injury alone may not mandate imaging if low-risk criteria met.
GCS 15 and no deficits are reassuring but do not rule out injury.
3. A trauma patient with a suspected tension pneumothorax undergoes needle decompression. Which anatomical
landmark is most appropriate for this procedure in an adult?
A) 2nd intercostal space, midclavicular line
Page 1
, B) 5th intercostal space, anterior axillary line
C) 4th intercostal space, midaxillary line
D) 7th intercostal space, posterior axillary line
' Correct Answer: A
Rationale: Needle decompression is traditionally performed at the 2nd intercostal space, midclavicular line, though
the 5th intercostal space anterior axillary line is an alternative. Tube thoracostomy uses the 5th intercostal space.
Other sites are incorrect.
4. Which of the following is the most sensitive indicator of early hemorrhagic shock in a trauma patient?
A) Systolic blood pressure <90 mmHg
B) Heart rate >100 bpm
C) Narrowed pulse pressure
D) Decreased urine output
' Correct Answer: C
Rationale: Narrowed pulse pressure (difference between systolic and diastolic) is an early sign of hemorrhagic
shock due to compensatory vasoconstriction. Tachycardia is common but nonspecific. Hypotension is a late sign.
Decreased urine output is also late.
5. A patient with severe traumatic brain injury has a Glasgow Coma Scale score of 6. Which of the following is the
most appropriate initial management to prevent secondary brain injury?
A) Hyperventilation to maintain PaCO2 at 25-30 mmHg
B) Maintenance of normocapnia and normoxia
C) Administration of hypotonic fluids
D) Permissive hypotension to reduce cerebral edema
' Correct Answer: B
Rationale: Normocapnia and normoxia are critical to avoid secondary brain injury. Hyperventilation can cause
vasoconstriction and ischemia. Hypotonic fluids worsen cerebral edema. Permissive hypotension is contraindicated
as it reduces cerebral perfusion pressure.
6. In a patient with suspected abdominal trauma, which finding on FAST examination is most indicative of
immediate operative intervention?
A) Free fluid in the pericardial sac
B) Free fluid in Morison's pouch
C) Free fluid in the splenorenal recess
D) Free fluid in the pelvis
' Correct Answer: B
Rationale: Free fluid in Morison's pouch (hepatorenal recess) is highly suggestive of intra-abdominal hemorrhage,
often requiring surgery. Pericardial fluid indicates tamponade. Splenorenal and pelvic fluid can be from various
sources but are less specific for immediate operative need.
7. Which of the following is the most appropriate initial fluid resuscitation strategy for a burn patient with >20%
total body surface area burns?
A) Lactated Ringer's at 2 mL/kg/%TBSA over 24 hours
B) Lactated Ringer's at 4 mL/kg/%TBSA over 24 hours
C) Normal saline at 1 mL/kg/%TBSA over 24 hours
D) Colloids at 1 mL/kg/%TBSA over 24 hours
' Correct Answer: B
Page 2
,Rationale: The Parkland formula recommends 4 mL/kg/%TBSA of Lactated Ringer's over 24 hours, with half
given in the first 8 hours. Other formulas exist but 4 mL/kg is standard in ATLS. Normal saline and colloids are not
first-line.
8. A patient with a suspected pelvic fracture and hemodynamic instability undergoes application of a pelvic binder.
Which of the following is the primary goal of this intervention?
A) Reduce pelvic volume to tamponade bleeding
B) Align the fracture for surgical fixation
C) Prevent further displacement of the fracture
D) Relieve pain associated with the fracture
' Correct Answer: A
Rationale: Pelvic binders reduce pelvic volume, which can tamponade venous bleeding and stabilize clot
formation. They do not align fractures definitively or primarily relieve pain. Prevention of displacement is
secondary.
9. Which of the following is the most reliable method to confirm endotracheal tube placement in a trauma patient?
A) Auscultation of breath sounds over the epigastrium
B) Chest rise and fall
C) Continuous waveform capnography
D) Fogging of the endotracheal tube
' Correct Answer: C
Rationale: Continuous waveform capnography is the gold standard for confirming and monitoring endotracheal
tube placement. Auscultation, chest rise, and tube fogging are unreliable and can be misleading.
10. Which statement most accurately characterizes the ATLS 11th edition recommendation regarding prehospital
spinal motion restriction (SMR) in an alert, neurologically intact trauma patient with a distracting injury?
A) Rigid cervical collar plus long backboard is mandated until MRI excludes ligamentous injury.
B) SMR should be applied selectively based on mechanism and exam, and the backboard should be removed as
soon as feasible to prevent pressure injury.
C) Spinal immobilization is no longer recommended in any blunt trauma patient.
D) Cervical collar alone is sufficient and backboard use is contraindicated in all patients.
' Correct Answer: B
Rationale: ATLS 11th edition endorses selective spinal motion restriction guided by validated decision rules, and
emphasizes early removal of the rigid backboard because prolonged use causes pressure ulcers and respiratory
compromise. Mandatory long-backboard immobilization (A) and complete abandonment of immobilization (C) are
both incorrect extremes, and D misstates collar/backboard indications.
11. In the ATLS primary survey, which finding most reliably distinguishes tension pneumothorax from massive
hemothorax before imaging is available?
A) Tracheal deviation toward the affected side
B) Hyperresonance to percussion with hypotension and absent breath sounds
C) Dullness to percussion with flat neck veins
D) Subcutaneous emphysema extending into the neck
' Correct Answer: B
Rationale: Tension pneumothorax produces hyperresonance, absent breath sounds, and obstructive shock from
mediastinal shift, whereas massive hemothorax produces dullness and often flat neck veins from hypovolemia.
Tracheal deviation toward the affected side (A) is anatomically wrong for tension physiology, and subcutaneous
emphysema (D) is nonspecific.
Page 3
, 12. A trauma patient arrives with a Glasgow Coma Scale score of 8, systolic BP 70 mmHg, and HR 130. After 1 L of
warmed crystalloid, BP remains 75/40. According to ATLS 11th edition, which is the most appropriate next step?
A) Immediate CT of the head and abdomen before any blood products
B) Transfusion of balanced blood products while pursuing hemorrhage control
C) Vasopressor infusion to maintain mean arterial pressure above 65 mmHg
D) Rapid 3 L crystalloid bolus to restore euvolemia
' Correct Answer: B
Rationale: ATLS 11th edition emphasizes early balanced resuscitation with blood products and definitive
hemorrhage control for non-responders to initial crystalloid, avoiding large-volume crystalloid and vasopressors in
undifferentiated hemorrhagic shock. CT before resuscitation (A) delays hemorrhage control, and D contradicts
damage-control resuscitation principles.
13. Which burn patient meets ATLS 11th edition criteria for immediate transfer to a verified burn center?
A) Superficial partial-thickness burns covering 8% TBSA in an otherwise healthy patient
B) Full-thickness burns involving the face, hands, or perineum regardless of TBSA
C) Isolated chemical burn of the forearm with adequate irrigation
D) Sunburn with blistering over the shoulders
' Correct Answer: B
Rationale: ATLS 11th edition lists full-thickness burns involving critical areas (face, hands, feet, genitalia,
perineum, major joints) and any burn with inhalation injury or significant comorbidities as automatic burn-center
referral criteria. The other options do not meet these thresholds.
14. Which statement best reflects the ATLS 11th edition approach to the trauma patient with suspected pelvic
fracture and hemodynamic instability?
A) Immediate open reduction and internal fixation is the first-line intervention.
B) Application of a pelvic binder at the level of the greater trochanters plus early angioembolization or
preperitoneal packing based on physiology
C) Diagnostic peritoneal lavage is mandatory before any intervention.
D) Traction with a femoral traction splint is contraindicated in all pelvic fractures.
' Correct Answer: B
Rationale: ATLS 11th edition recommends temporary pelvic stabilization with a binder at the greater trochanter
level, followed by hemorrhage-control strategies (angioembolization or preperitoneal packing) dictated by
hemodynamic status. Immediate ORIF (A) is not the initial step in the unstable patient, and DPL (C) has been
largely superseded by FAST.
15. Which finding on FAST most strongly indicates the need for immediate operative intervention in a
hemodynamically unstable blunt trauma patient?
A) Anechoic fluid in Morison's pouch with hypotension refractory to resuscitation
B) Pericardial fat stripe without fluid
C) Isolated pleural effusion
D) Increased echogenicity of the pancreas
' Correct Answer: A
Rationale: Free fluid in Morison's pouch in a hypotensive patient who does not respond to resuscitation is a classic
indication for immediate laparotomy per ATLS 11th edition. The other findings are either normal variants or
unrelated to acute hemoperitoneum requiring surgery.
16. A trauma patient with suspected traumatic brain injury has a GCS of 5 and is being intubated. According to
ATLS 11th edition, which ventilation target best minimizes secondary brain injury?
