Trauma Life Support Exam Prep
DOCUMENT OVERVIEW
• This comprehensive 200-question exam provides thorough coverage of PHTLS
10th Edition core competencies with verified answers and detailed rationales to
reinforce clinical decision-making and trauma assessment mastery.
• Study this material by working through questions systematically, carefully
reviewing rationales for both correct and incorrect options to deepen
understanding of prehospital trauma management principles and protocols.
1. QUESTION: When arriving at a trauma scene, what is your PRIMARY
responsibility before patient assessment?
A) Begin immediate patient care
B) Establish scene safety and hazard control
C) Call for additional resources
D) Locate all patients
E) Document the mechanism of injury
CORRECT ANSWER: B) Establish scene safety and hazard control
RATIONALE: Scene safety is the foundational principle in PHTLS. You cannot help
patients if you become injured or contaminated. Establishing scene safety includes
identifying hazards such as traffic, downed power lines, chemical spills, violence, or
,unstable structures. This assessment must occur before you enter the scene or
approach patients. All other actions are secondary to ensuring the responder's
safety first.
2. QUESTION: What does the primary survey in trauma assessment focus on
identifying?
A) Chronic medical conditions
B) Life-threatening conditions that require immediate intervention
C) Insurance information
D) Patient comfort and pain management
E) Historical medical events
CORRECT ANSWER: B) Life-threatening conditions that require immediate
intervention
RATIONALE: The primary survey (now called initial assessment in PHTLS) uses the
ABCDE approach to identify and manage immediately life-threatening conditions.
This includes Airway maintenance, Breathing adequacy, Circulation with
hemorrhage control, Disability assessment, and Exposure while preventing
hypothermia. The primary survey takes precedence over all other assessment
activities because these conditions will kill the patient if not addressed immediately.
3. QUESTION: During the assessment of a trauma patient, when should the
secondary survey be performed?
A) Before the primary survey
B) After the primary survey is complete and life threats are managed
C) Only if the patient is conscious
D) Only at the hospital
E) Simultaneously with the primary survey
,CORRECT ANSWER: B) After the primary survey is complete and life threats
are managed
RATIONALE: The secondary survey is performed only after the primary survey is
complete and immediate life threats have been identified and managed. This
systematic head-to-toe assessment examines all body regions for injuries that may
not be immediately life-threatening but require documentation and treatment.
Performing the secondary survey before addressing life threats could delay critical
interventions and compromise patient survival.
4. QUESTION: What is the most common cause of preventable death in
trauma patients?
A) Head injury
B) Abdominal injury
C) Hemorrhage
D) Spinal cord injury
E) Airway obstruction
CORRECT ANSWER: C) Hemorrhage
RATIONALE: Uncontrolled hemorrhage is the leading preventable cause of death in
trauma patients. PHTLS emphasizes hemorrhage control as a critical component of
initial management. Deaths from hemorrhage can occur in the first few minutes to
hours after injury, and early aggressive hemorrhage control through direct
pressure, elevation, tourniquet application, and rapid transport significantly
improves survival rates.
5. QUESTION: In the context of shock, which of the following best describes
compensatory shock?
A) The patient has lost consciousness
, B) Blood pressure remains relatively normal despite blood loss due to
compensatory mechanisms
C) The patient requires immediate transfusion
D) Vital organs have already failed
E) The patient is in complete cardiovascular collapse
CORRECT ANSWER: B) Blood pressure remains relatively normal despite blood
loss due to compensatory mechanisms
RATIONALE: In compensatory shock, the body's mechanisms (increased heart rate,
peripheral vasoconstriction, increased respiratory rate) maintain relatively normal
blood pressure despite ongoing blood loss. This state is reversible with appropriate
intervention. Recognizing compensatory shock is critical because patients may
appear relatively stable while actually losing blood volume, and delaying
intervention during this phase can result in progression to decompensatory shock
and death.
6. QUESTION: What is the primary indicator that a patient has progressed
from compensatory shock to decompensatory shock?
A) Increased heart rate
B) Increased respiratory rate
C) A fall in blood pressure
D) Anxiety
E) Pale skin
CORRECT ANSWER: C) A fall in blood pressure
RATIONALE: The drop in blood pressure is the hallmark sign of decompensatory
shock, indicating that compensatory mechanisms have failed and organ perfusion
is no longer adequate. By the time hypotension develops, significant blood loss has
already occurred. This is a critical point in the shock trajectory where immediate
