Content Area Overview
This actual examination reflects the comprehensive trauma knowledge required for success on the ATLS
Post Test 4. It is designed to evaluate the student's understanding of the systematic approach to trauma
care, from the primary survey to definitive management. Questions are structured to assess recall of key
principles, application of clinical algorithms to complex trauma scenarios, and analysis of life-threatening
injury patterns. This authentic question bank represents the real exams used in the course and serves as
a comprehensive resource for trauma surgeons, emergency physicians, residents, and advanced clinical
providers demonstrating mastery of ATLS content for the 2026/2027 academic year.
SECTION 1: Primary Survey and Initial Resuscitation
(Questions 1–10)
Question 1
A 42-year-old male is brought to the emergency department after a high-speed motor vehicle collision.
He is responsive to painful stimuli but not following commands. His airway is patent, but he has gurgling
respirations and vomitus in his oropharynx. The trauma team leader's first action should be:
A. Insert an oropharyngeal airway and suction the airway
B. Immediately perform rapid sequence intubation with in-line cervical stabilization
C. Logroll the patient to clear the vomitus
D. Obtain a chest x-ray before airway intervention
B. Immediately perform rapid sequence intubation with in-line cervical stabilization [CORRECT]
,The best answer is immediately perform rapid sequence intubation with in-line cervical stabilization.
This patient has a compromised airway—gurgling respirations, vomitus, and altered mental status (not
following commands) indicate he cannot protect his airway. In trauma, airway always comes first in the
primary survey. Cervical spine immobilization is maintained throughout because all trauma patients are
assumed to have a C-spine injury until proven otherwise. Suctioning is important but does not secure
the airway; the patient needs definitive airway control. This aligns with ATLS guidelines for airway
management in trauma.
Correct Answer: B
Question 2
A 28-year-old construction worker falls from a second-story scaffold and presents with absent breath
sounds on the left, tracheal deviation to the right, distended neck veins, and hypotension (BP 72/40).
The trauma team leader should perform which immediate intervention?
A. Insert a large-bore chest tube in the left 5th intercostal space
B. Perform needle decompression in the 2nd intercostal space at the midclavicular line on the left
C. Obtain an upright chest x-ray to confirm the diagnosis
D. Begin positive pressure ventilation before decompression
B. Perform needle decompression in the 2nd intercostal space at the midclavicular line on the left
[CORRECT]
This choice is correct because tension pneumothorax is a clinical diagnosis—never wait for imaging. The
classic findings include absent breath sounds, tracheal deviation away from the affected side, JVD, and
hypotension. Needle decompression with a 14-gauge needle at least 3.25 inches long in the 2nd
intercostal space, midclavicular line, on the affected side converts the tension pneumothorax to a simple
pneumothorax and is immediately life-saving. Chest tube placement follows, but decompression comes
first. This matches the systematic approach to trauma for immediate thoracic decompression.
Correct Answer: B
Question 3
A 35-year-old female pedestrian struck by a car presents with a respiratory rate of 34, oxygen saturation
86% on room air, and paradoxical chest wall movement on the left side involving ribs 5–8. Her BP is
100/60. The most appropriate immediate management for her breathing is:
A. Immediate endotracheal intubation and mechanical ventilation
B. High-flow oxygen via non-rebreather mask and aggressive analgesia with close monitoring
, C. Needle decompression of the left hemithorax
D. Chest tube insertion on the left side
B. High-flow oxygen via non-rebreather mask and aggressive analgesia with close monitoring
[CORRECT]
The best answer is high-flow oxygen via non-rebreather mask and aggressive analgesia with close
monitoring. This patient has a flail chest—paradoxical movement of a free-floating segment due to
multiple contiguous rib fractures. The real problem is usually the underlying pulmonary contusion and
pain-induced splinting, not the flail segment itself. Adequate analgesia (epidural, intercostal nerve
blocks, or IV opioids) allows deep breathing and prevents atelectasis and pneumonia. Intubation is
reserved for respiratory failure, not routine flail chest. Needle decompression and chest tube are not
indicated here. This aligns with ATLS guidelines for flail chest management.
Correct Answer: B
Question 4
A 50-year-old male involved in a motor vehicle collision presents with a heart rate of 136, BP 84/50, cool
clammy skin, and delayed capillary refill. He has received 2 liters of warmed lactated Ringer's without
significant improvement in his vital signs. According to ATLS hemorrhagic shock classification, this
patient is most consistent with which class of shock?
A. Class I
B. Class II
C. Class III
D. Class IV
C. Class III [CORRECT]
This choice is correct because Class III hemorrhagic shock involves 30–40% blood volume loss
(approximately 1500–2000 mL in a 70 kg adult), presenting with heart rate >120, systolic BP decreased,
altered mental status, and significant peripheral vasoconstriction (cool, clammy skin, delayed capillary
refill). The failure to respond to 2 liters of crystalloid suggests ongoing hemorrhage requiring blood
products. Class I is <15% loss with minimal signs, Class II is 15–30% with normal BP but tachycardia, and
Class IV is >40% with profound hypotension and imminent death. This matches ATLS classification
criteria for hemorrhagic shock.
Correct Answer: C
