ATLS POST TEST COMPREHENSIVE EXAM \
2026 latest updated test
1. Which of the following is the most common cause of preventable death after
trauma?
A) Sepsis
B) Hemorrhage
C) Traumatic brain injury
D) Multiple organ failure
Correct Answer💜: B) Hemorrhage
Rationale: Hemorrhage is the leading cause of preventable death in trauma
patients, emphasizing the importance of early recognition and control of
bleeding.
2. During the primary survey, which intervention takes priority in a trauma
patient with a suspected tension pneumothorax?
A) Endotracheal intubation
B) Needle decompression
C) Chest tube placement
D) Rapid fluid administration
Correct Answer💜: B) Needle decompression
Rationale: Tension pneumothorax is a life-threatening condition requiring
immediate needle decompression (2nd intercostal space, midclavicular line or 5th
intercostal space, midaxillary line) to relieve pressure.
,3. A trauma patient with a Glasgow Coma Scale (GCS) score of 6 should first
receive:
A) Immediate head CT
B) Endotracheal intubation
C) Mannitol administration
D) Cervical spine immobilization
Correct Answer💜: B) Endotracheal intubation
Rationale: A GCS ≤ 8 indicates the inability to protect the airway and requires
securing the airway to prevent hypoxia and hypercapnia.
4. Which of the following is the most reliable indicator of hypovolemic shock in
a trauma patient?
A) Tachycardia
B) Hypotension
C) Altered mental status
D) Decreased urine output
Correct Answer💜: C) Altered mental status
Rationale: Altered mental status is an early and sensitive sign of shock due to
cerebral hypoperfusion, often occurring before a significant drop in blood
pressure.
5. A patient with a pelvic fracture and hemodynamic instability should first
receive:
A) External fixation
B) Pelvic angiography
C) Pelvic binder application
,D) Exploratory laparotomy
Correct Answer💜: C) Pelvic binder application
Rationale: A pelvic binder reduces pelvic volume and provides stability, which
helps tamponade venous bleeding in unstable fractures. It serves as a critical
temporizing measure.
6. The preferred fluid for initial resuscitation in trauma patients is:
A) Normal saline
B) Lactated Ringer’s
C) Hypertonic saline
D) Packed red blood cells (PRBCs)
Correct Answer💜: B) Lactated Ringer’s
Rationale: Lactated Ringer’s is preferred over large volumes of normal saline due
to its more physiologic composition and lower risk of hyperchloremic metabolic
acidosis.
7. Which of the following findings is most suggestive of cardiac tamponade?
A) Hypotension and unilateral breath sounds
B) Distended neck veins and muffled heart sounds
C) Tachycardia and widened pulse pressure
D) Subcutaneous emphysema and cyanosis
Correct Answer💜: B) Distended neck veins and muffled heart sounds
Rationale: These are components of Beck's triad (hypotension, distended neck
veins, muffled heart sounds), which is classic for cardiac tamponade.
8. What is the "lethal triad" in trauma patients?
A) Hypotension, bradycardia, and hypoxia
, B) Hypothermia, acidosis, and coagulopathy
C) Hyperthermia, tachycardia, and hypertension
D) Hypoglycemia, hyponatremia, and hypokalemia
Correct Answer💜: B) Hypothermia, acidosis, and coagulopathy
Rationale: This self-perpetuating triad worsens trauma outcomes and must be
prevented or corrected early to improve survival.
9. Which injury is most likely if a patient has abdominal tenderness with a
seatbelt sign?
A) Small bowel injury
B) Kidney contusion
C) Liver laceration
D) Bladder rupture
Correct Answer💜: A) Small bowel injury
Rationale: The seatbelt sign (ecchymosis across the abdomen) is associated with
an increased risk of hollow viscus injury, such as small bowel perforation from
compression.
10. The first step in managing a patient with suspected spinal cord injury is:
A) MRI of the spine
B) High-dose steroids
C) Spinal immobilization
D) Neurosurgical consultation
Correct Answer💜: C) Spinal immobilization
Rationale: Immobilization (cervical collar, backboard) prevents secondary injury
to the spinal cord during evaluation and transport.
