TCAR (Trauma Care After Resuscitation) Post-Test
exam QUESTIONS AND CORRECT DETAILED
SOLUTIONS WITH RATIONALES LATEST THIS YEAR
(2026-2027)
acomplete TCAR (Trauma Care After Resuscitation) Post-Test exam consisting of 150
randomized, scenario-based multiple-choice questions with italicized rationales. No subtopics
or domain labels. All questions are exam-relevant for the latest TCAR
certification/recertification.
1.Helmets and automobile airbags work because they:
A) prevent blows to the head
B) reduce acceleration injuries
C) increase deceleration speed
D) add deceleration distance
Answer: B
Helmets and airbags increase the time and distance over which deceleration occurs, reducing
the force transmitted to the brain (Newton's second law: force = mass ×
acceleration/deceleration).

2. Which of the following statements best describes knife wounds? Their velocity is _____, the
temporary cavity _____, and damage _____.
A) low; depends on the size of the knife; is usually extensive
B) low; is insignificant; is limited to structures directly in object's path
C) high; will be small; affects structures at some distance from the wound tract
D) high; may be massive; results in widespread tissue destruction
Answer: B
Knife wounds are low-velocity injuries with no significant temporary cavitation; damage is
confined to the blade's path.
3. Shock occurs when:
A) the sodium-potassium pump fails
B) ATP levels are less than lactic acid levels
C) cellular oxygen demand is greater than supply
D) aerobic metabolism exceeds anaerobic metabolism
Answer: C
Shock is defined as inadequate tissue perfusion and oxygenation leading to cellular hypoxia.

4. What is the single most common cause of preventable death after injury?
A) Airway obstruction
B) Tension pneumothorax
C) Hemorrhage
D) Spinal cord injury
Answer: C
Uncontrolled hemorrhage remains the leading cause of preventable death in trauma, making
early recognition and control critical.
5. _____ shock is the most common type of shock immediately after traumatic injury.
A) Distributive
B) Septic
C) Cardiogenic
D) Hypovolemic
Answer: D
Acute blood loss or fluid shifts cause hypovolemic shock in the early post-injury phase.
6. Which findings suggest a trauma patient is experiencing cardiogenic shock?
A) Bradycardia, cyanosis, and elevated mean arterial pressure
, Page 4 of 75
B) High shock index, mottling, and hypotension
C) Tachycardia, flushing, and widened pulse pressure
D) Pallor, coarse breath sounds, and hypertension
Answer: B
Cardiogenic shock in trauma (e.g., blunt myocardial injury) presents with pump failure signs
despite adequate preload.
7. Normalizing a trauma patient's body temperature helps control bleeding because
hypothermia:
A) produces shivering and makes platelets hyperactive
B) causes platelet dysfunction and clotting system failure
C) stimulates the clotting cascade and reduces blood pressure
D) increases blood viscosity and slows bleeding
Answer: B
Hypothermia impairs platelet function and coagulation enzyme activity, worsening bleeding;
rewarming restores hemostasis.
8. A patient involved in a high-speed MVC is found unresponsive with irregular respirations and
unequal pupils. Which injury is most likely responsible?
