PHTLS 10th Edition Post-Test ()
Q1. According to PHTLS 10th Edition philosophy, which statement best describes the role of critical
thinking in prehospital trauma care?
A. Critical thinking is only necessary for complex multi-system trauma patients, not for
straightforward injuries
B. Critical thinking is a dynamic process requiring the provider to assess the situation, the patient,
and available resources, then develop, initiate, and adjust a plan of action as conditions change
C. Critical thinking should be applied only after completing the primary survey and gathering all
diagnostic information
D. Critical thinking is the exclusive domain of physicians and should not influence the decisions of
prehospital care practitioners
Correct Answer: B
Rationale: PHTLS defines critical thinking as a dynamic, continuous process in which the practitioner
assesses the situation, the patient, and available resources, then uses that information to decide on
and provide the best care. The plan must be initiated, reassessed, and adjusted as the patient's
condition or circumstances change. It is not reserved for physicians or limited to complex cases; it is
a foundational expectation of every prehospital care practitioner at all times. Choice A is incorrect
because critical thinking applies to all patients. Choice C is incorrect because critical thinking begins
immediately upon arrival and continues throughout care. Choice D is incorrect because PHTLS
emphasizes that all providers must engage in critical thinking.
Q2. A prehospital provider prefers to apply a pelvic binder before initiating IV access in a patient
with suspected pelvic fracture and signs of shock. A colleague argues that IV access should come
first. According to PHTLS principles, which concept resolves this disagreement?
A. The provider with more years of experience should determine the sequence of interventions
B. Preferences are individual choices that do not override evidence-based principles, so the
intervention supported by the strongest evidence should take priority
C. Both interventions are preferences, so either order is acceptable as long as both are performed
D. The principle of rapid transport should override both interventions, and neither should be
performed on scene
Correct Answer: B
pg. 1
,Rationale: PHTLS distinguishes between principles and preferences. Principles define the duties
required of prehospital care practitioners in optimizing patient survival and are based on evidence-
based science. Preferences are individual choices that do not override principles. When a conflict
arises, the evidence-based principle dictates the correct course of action. Hemorrhage control
(including pelvic binding for pelvic hemorrhage) is a principle-based intervention that takes priority.
Choice A is incorrect because experience does not override evidence. Choice C is incorrect because
not all interventions carry equal weight. Choice D is incorrect because hemorrhage control should
not be delayed for transport.
Q3. Which of the following statements best describes the relationship between the Golden Period
and the Platinum Ten Minutes in PHTLS?
A. The Golden Period refers to the first 10 minutes of on-scene care, while the Platinum Ten Minutes
refers to total transport time
B. The Platinum Ten Minutes is a subset of the Golden Period that specifically emphasizes minimizing
on-scene time during the first 10 minutes after injury, because the entire period from injury to
definitive care is critical for survival
C. The Golden Period and the Platinum Ten Minutes are interchangeable terms describing the same
time window
D. The Platinum Ten Minutes replaces the Golden Period concept in the 10th Edition as the primary
time-based principle
Correct Answer: B
Rationale: The Golden Period is the total time from injury to arrival at the appropriate site for
definitive care, which is critical for survival. The Platinum Ten Minutes specifically refers to the first
10 minutes after injury, during which prehospital providers should aim to minimize on-scene
interventions and expedite transport. The Platinum Ten Minutes reinforces the Golden Period
concept by emphasizing the urgency of the earliest phase of care. Choice A reverses the definitions.
Choice C is incorrect because they describe different but related time frames. Choice D is incorrect
because both concepts remain valid in the 10th Edition.
Q4. A trauma system is classified based on its capability to provide definitive care. A Level I trauma
center is best described as one that:
A. Provides initial evaluation and stabilization before transferring all patients to a higher-level facility
B. Has 24-hour immediate availability of all specialties, personnel, and equipment necessary to
manage the most severely injured patients
C. Serves primarily rural communities and provides basic trauma care with limited surgical capability
D. Focuses exclusively on rehabilitation and long-term recovery of trauma patients
Correct Answer: B
Rationale: A Level I trauma center provides comprehensive trauma care with 24-hour immediate
availability of all specialties, personnel, and equipment necessary to manage the most severely
injured patients. It also has a commitment to trauma research and education. Choice A describes a
Level III or IV facility. Choice C describes a lower-level trauma center. Choice D is incorrect because
rehabilitation is a component but not the defining characteristic of a Level I center.
pg. 2
,Q5. According to PHTLS 10th Edition, which statement represents the foundational belief regarding
trauma patient care?
A. Only Level I trauma centers should manage trauma patients
B. All trauma patients deserve the best possible care, and every practitioner has a duty to apply
critical thinking to optimize outcomes
C. Prehospital care should focus solely on rapid transport without intervention
D. Critical thinking is only necessary for complex multi-system trauma
Correct Answer: B
Rationale: The PHTLS philosophy states that all trauma patients deserve the best possible care and
that every practitioner has a duty to apply critical thinking to optimize patient outcomes. This
principle underpins all PHTLS education and guides clinical decision-making in the prehospital
environment. Choice A is incorrect because not all patients require Level I care. Choice C is incorrect
because prehospital interventions save lives. Choice D is incorrect because critical thinking applies to
all patients regardless of complexity.
Q6. A prehospital provider wants to use a non-evidence-based wound dressing because they have
always used it. According to PHTLS principles, which statement is correct?
A. Preferences override principles when the provider has extensive experience
B. Principles define the duties required to optimize patient survival and outcomes; preferences do
not override evidence-based principles
C. Individual preferences take priority in the field when protocols are unclear
D. Both principles and preferences carry equal weight in clinical decision-making
Correct Answer: B
Rationale: The science of medicine provides the principles of medical care. Principles define the
duties required of the prehospital care practitioner in optimizing patient survival and outcome.
Preferences are individual choices that do not override evidence-based principles, regardless of
provider experience or personal habit. Choice A is incorrect because experience does not supersede
evidence. Choice C is incorrect because protocols and principles guide practice. Choice D is incorrect
because principles take precedence over preferences.
Q7. The Golden Period in trauma care refers to which time interval?
A. The first 60 minutes from injury to hospital arrival
B. The time from injury to arrival at the appropriate site for definitive care
C. The first 24 hours of in-hospital trauma resuscitation
D. The period during which tourniquets can be safely applied before ischemic damage
Correct Answer: B
Rationale: The Golden Period is defined as the time from injury to arrival at the appropriate site for
definitive care, which is critical to patient survival. One of the most important responsibilities of a
prehospital care practitioner is to minimize on-scene time and expedite both field care and
pg. 3
, transport. Choice A describes a common misconception. Choice C refers to in-hospital care. Choice D
describes tourniquet safety windows, not the Golden Period.
Q8. A 34-year-old motorcycle rider was ejected and struck a tree. He is pale, diaphoretic, tachycardic
at 128, BP 94/62, RR 24, GCS 14. Which shock classification best describes his presentation per
PHTLS 10th Edition?
A. Compensated shock with adequate tissue perfusion
B. Decompensated (progressive) hemorrhagic shock
C. Irreversible hemorrhagic shock
D. Neurogenic shock from spinal injury
Correct Answer: B
Rationale: This patient shows tachycardia, narrowed pulse pressure, mild hypotension, and altered
mental status. These represent decompensated hemorrhagic shock where compensatory
mechanisms are failing. Choice A is incorrect because the patient is hypotensive with altered
mentation. Choice C is incorrect because irreversible shock presents with profound hypotension,
bradycardia, and unresponsiveness. Choice D is incorrect because neurogenic shock presents with
hypotension without tachycardia and warm dry skin.
Q9. A 45-year-old restrained driver in a high-speed frontal collision has a steering wheel deformity,
seat belt sign across the chest, and complains of chest pain. HR 110, BP 140/90. Which kinematic
principle explains why this patient is at high risk for serious injury despite "normal" vital signs?
A. The patient is in compensated shock with maintained blood pressure
B. Energy transfer follows Newton's Second Law of Acceleration
C. The three collisions principle (vehicle, body, organ) explains internal injury patterns
D. Seat belts prevent all significant thoracic injuries
Correct Answer: C
Rationale: The "three collisions" concept describes: (1) vehicle collision, (2) body collision with
interior, and (3) organ collision within body cavities. The steering wheel deformity indicates
significant force transfer. The seat belt sign suggests deceleration forces across the chest, risking
myocardial contusion, aortic injury, and hollow viscus rupture. Choice A describes a shock state, not
a kinematic principle. Choice B is relevant but less specific than the three collisions principle for
predicting internal injury patterns. Choice D is incorrect and dangerous; seat belts reduce but do not
prevent thoracic injuries.
Q10. In PHTLS 10th Edition, the primary survey is best remembered by which mnemonic?
A. ABCDE
B. XABCDE
C. SAMPLE
D. AVPU
Correct Answer: B
