SECTION 1 | QUESTIONS 1-25
Pre-Test Assessment
Core Trauma Concepts and Baseline Knowledge
Q1. Which statement BEST defines the Golden Period in prehospital trauma care?
A. The first 10 minutes of EMS on-scene time, during which the scene size-up must be completed
B. The period immediately after airway placement, during which ventilation must be optimized
C. The time interval extending from the moment of injury until the patient reaches definitive surgical
care [CORRECT]
D. The window during which the secondary survey must be completed before transport begins
Correct Answer: C
Rationale: The Golden Period is defined as the interval from the time of injury until the patient reaches
definitive care, and it drives the entire PHTLS philosophy of rapid assessment and early transport. It is not
limited to on-scene EMS time, as in option A, nor is it tied to airway management or the secondary survey as
in options B and D. Because mortality from uncontrolled internal hemorrhage climbs with every passing
minute, the prehospital team minimizes scene time and moves the patient toward surgical resources rather
than consuming the Golden Period on low-yield interventions.
Q2. An instructor reviews the concept of the Platinum 10 Minutes with a class of prehospital providers.
What is the key expectation for a critically injured trauma patient?
A. Limit on-scene time to approximately 10 minutes, performing only essential, life-saving
interventions before departing [CORRECT]
B. Complete a detailed head-to-toe secondary survey within 10 minutes of patient arrival
C. Administer every anticipated medication within the first 10 minutes of patient contact
D. Remain on scene at least 10 minutes to observe the patient for deterioration before initiating
transport
Correct Answer: A
Rationale: The Platinum 10 Minutes is a PHTLS time-management goal stating that critically injured
patients should reach the ambulance within about 10 minutes, with scene activity restricted to interventions
that directly preserve life, such as hemorrhage control, airway management, and spinal motion restriction.
Completing a full secondary survey on scene (B) delays definitive care for a critical patient. Option C is
arbitrary and does not reflect PHTLS practice, and option D inverts the principle entirely, since prolonged
PHTLS Pre and Post Test | 2026/2027 Edition 1
,PHTLS PRE AND POST TEST - 2026/2027 EXAMINATION PREPARATION
observation on scene wastes the Golden Period.
Q3. In the current PHTLS primary assessment mnemonic XABCDE, what does the letter X represent?
A. X-ray assessment of the chest and pelvis before transport
B. Exposure of the patient to check for hidden injuries
C. Exhalation assessment to confirm adequate ventilation
D. eXsanguinating hemorrhage, meaning immediate control of catastrophic external bleeding
[CORRECT]
Correct Answer: D
Rationale: The X in XABCDE stands for eXsanguinating hemorrhage, reflecting updated evidence that
massive external bleeding can kill faster than an obstructed airway and must be controlled first with direct
pressure, wound packing, or an immediate tourniquet. Option A is incorrect because plain radiography is not
a prehospital primary survey tool, option B describes the E component of the sequence, and option C is not a
recognized assessment step. This sequencing update is one of the most frequently tested PHTLS concepts on
current examinations.
Q4. According to the trimodal distribution of trauma deaths, which group of patients dies during the
SECOND mortality peak, and what does this imply for prehospital care?
A. Deaths within seconds to minutes from devastating brain or cord injury, implying no intervention
can help
B. Deaths occurring hours after injury from airway compromise, hemorrhage, or hemopneumothorax,
implying that rapid assessment and intervention can prevent many of these deaths [CORRECT]
C. Deaths days to weeks after injury from sepsis and multi-organ failure, implying prehospital care has
no measurable influence
D. Deaths occurring only in the operating room, implying that all prehospital effort should be
postponed until hospital arrival
Correct Answer: B
Rationale: The second peak of the trimodal death curve occurs within the first several hours (the Golden
Hour) and is dominated by treatable killers such as airway obstruction, tension pneumothorax, and
uncontrolled hemorrhage, which is precisely where skilled prehospital care saves lives. Option A describes
the first peak, where injuries are often unsurvivable despite optimal care. Option C describes the third peak,
driven by sepsis and multi-organ dysfunction, which is influenced by early quality care but occurs days later.
Option D contradicts the entire evidence base for prehospital trauma intervention.
Q5. You arrive at a vehicle collision and find an unresponsive adult with snoring respirations AND a
strong arterial jet of blood from an open left groin wound. According to current PHTLS sequencing,
what should you do FIRST?
A. Insert an oropharyngeal airway and suction the airway before touching the bleeding wound
B. Immediately control the groin hemorrhage with direct pressure or a junctional tourniquet, then
correct the airway [CORRECT]
C. Perform a full spinal motion restriction setup with a long backboard before any other action
D. Obtain a complete set of vital signs to determine the shock class before intervening
Correct Answer: B
Rationale: Under the XABCDE approach, catastrophic external hemorrhage is addressed before the airway
because exsanguination from a femoral or junctional arterial wound can cause death in 2 to 3 minutes, faster
PHTLS Pre and Post Test | 2026/2027 Edition 2
, PHTLS PRE AND POST TEST - 2026/2027 EXAMINATION PREPARATION
than the airway problem in this scenario. Option A follows the outdated ABC sequence that PHTLS
replaced for this situation. Option C wastes irreplaceable minutes on packaging rather than life threat
control, and option D delays intervention when the bleeding is obvious and immediately treatable. Once
bleeding is controlled, the snoring airway is opened and protected.
Q6. The lethal triad of trauma death includes coagulopathy and acidosis. Which additional component
completes the triad that prehospital providers must actively prevent?
A. Hypoglycemia
B. Hyperkalemia
C. Seizure activity
D. Hypothermia [CORRECT]
Correct Answer: D
Rationale: The lethal triad consists of hypothermia, acidosis, and coagulopathy: cold and acidotic blood clot
poorly, and failure to clot worsens bleeding, which deepens shock and accelerates cooling in a
self-reinforcing spiral. Many trauma programs now add hypocalcemia to form the lethal diamond, but
hypocalcemia is not part of the classic triad. Hypoglycemia, hyperkalemia, and seizures (options A, B, and
C) are not components of the triad, although providers should still prevent hypothermia by removing wet
clothing, warming the patient, and warming intravenous fluids.
Q7. Which statement BEST describes the concept of permissive hypotension in the prehospital
management of penetrating torso trauma WITHOUT traumatic brain injury?
A. Tolerating a lower blood pressure (roughly systolic 80 to 90 mm Hg) until surgical hemorrhage
control, to avoid popping clots and worsening bleeding with aggressive fluids [CORRECT]
B. Maintaining the systolic pressure above 140 mm Hg to guarantee organ perfusion until surgery
C. Administering large-volume crystalloid boluses until the blood pressure normalizes completely
D. Withholding all fluids and medications because hypotension is protective in every trauma patient
Correct Answer: A
Rationale: Permissive hypotension accepts a gently reduced perfusion pressure until hemorrhage is
surgically controlled, because excessive fluid raises blood pressure, dilutes clotting factors, accelerates
dilutional coagulopathy, and can physically disrupt early clots. Option B describes hypertension, which is
never a trauma resuscitation goal. Option C describes the outdated high-volume crystalloid practice now
linked to increased bleeding and mortality. Option D is a distortion, since permissive hypotension is a
deliberate, monitored strategy that is abandoned when the patient also has traumatic brain injury, where
cerebral perfusion pressure must be preserved.
Q8. A restrained driver strikes a tree head-on. She appears to have ridden up and over the steering
wheel. Based on this kinematic pattern, which injury pattern should raise your index of suspicion
MOST?
A. Bilateral calcaneal and femoral neck fractures from axial loading
B. Posterior hip dislocation and knee injuries from the dashboard
C. Head, facial, cervical spine, and thoracic aortic injuries from the forward-and-upward body path
[CORRECT]
D. Isolated lower leg soft tissue injury with no internal damage expected
Correct Answer: C
