Section One: Questions 1–100
Question 1
What is the priority intervention for a patient arriving with a suspected tension pneumothorax?
A. Needle decompression
B. Chest tube insertion
,C. Supplemental oxygen
D. Endotracheal intubation
🟢 A. Needle decompression
🔴 RATIONALE: Tension pneumothorax is a life-threatening condition requiring immediate
decompression to relieve intrathoracic pressure; needle decompression is the immediate, bridge-to-
definitive-care intervention.
Question 2
A patient with a traumatic brain injury (TBI) begins exhibiting a widened pulse pressure and bradycardia.
This is indicative of:
A. Hypovolemic shock
B. Cushing triad
C. Neurogenic shock
D. Septic shock
🟢 B. Cushing triad
🔴 RATIONALE: Cushing triad (hypertension with widened pulse pressure, bradycardia, and irregular
respirations) is a classic late sign of increased intracranial pressure.
Question 3
Which of the following is the most reliable indicator of adequate tissue perfusion in a trauma patient?
A. Blood pressure
B. Heart rate
C. Level of consciousness
D. Urinary output
🟢 D. Urinary output
🔴 RATIONALE: Urinary output is a sensitive physiological indicator of organ perfusion, as the kidneys
receive significant blood flow; a decrease often signals inadequate systemic perfusion.
Question 4
During the primary survey, when should the cervical spine be immobilized?
,A. After the airway is established
B. Before addressing the airway
C. Simultaneously with airway assessment
D. During the secondary survey
🟢 C. Simultaneously with airway assessment
🔴 RATIONALE: To prevent further spinal cord injury, manual stabilization of the cervical spine must be
initiated immediately upon patient contact, coinciding with the airway assessment.
Question 5
What is the primary goal of the "Circulation" phase in the trauma assessment?
A. Complete physical exam
B. Identification and control of hemorrhage
C. Rapid fluid resuscitation
D. Electrocardiogram interpretation
🟢 B. Identification and control of hemorrhage
🔴 RATIONALE: The priority in the circulation phase is to identify and stop life-threatening external and
internal hemorrhage to prevent exsanguination.
Question 6
A patient presents with a flail chest. What is the primary concern for this patient?
A. Hemothorax
B. Underlying pulmonary contusion
C. Cardiac tamponade
D. Aortic rupture
🟢 B. Underlying pulmonary contusion
🔴 RATIONALE: While the chest wall injury is visible, the most frequent and dangerous complication of
flail chest is the underlying pulmonary contusion, which impairs gas exchange.
Question 7
When assessing for shock, which clinical sign typically appears earliest?
, A. Hypotension
B. Tachycardia
C. Decreased urine output
D. Altered mental status
🟢 B. Tachycardia
🔴 RATIONALE: Tachycardia is a compensatory mechanism mediated by the sympathetic nervous
system in response to decreased circulating volume, appearing before hypotension.
Question 8
What is the preferred route for fluid resuscitation in a trauma patient if peripheral access is unsuccessful?
A. Central venous line
B. Intraosseous (IO) access
C. Subcutaneous infusion
D. Endotracheal administration
🟢 B. Intraosseous (IO) access
🔴 RATIONALE: IO access is the recommended rapid-access route when peripheral intravenous access
cannot be established, providing a reliable pathway for fluids and medications.
Question 9
Which assessment finding is most characteristic of cardiac tamponade?
A. Distended neck veins, muffled heart sounds, and hypotension
B. Flat neck veins, diminished breath sounds, and tracheal deviation
C. Hypertension, tachycardia, and bounding pulses
D. Bradycardia, hypotension, and warm extremities
🟢 A. Distended neck veins, muffled heart sounds, and hypotension
🔴 RATIONALE: These findings represent Beck’s Triad, which is classic for cardiac tamponade, resulting
from the accumulation of fluid in the pericardial sac.
Question 10
In pediatric trauma patients, what is the most common cause of shock?
