SECTION 1: FOUNDATIONAL CONCEPTS, SCENE SAFETY, AND CRITICAL
THINKING
Questions 1-12 (10% of exam)
Q1. You are called to the scene of a multiple vehicle collision on a busy interstate
highway. As you approach, you see several patients walking around and one patient
lying motionless in the median. What is your FIRST priority?
● A. Immediately begin triaging the walking patients
● B. Treat the motionless patient first
● C. Assess the scene and ensure it is safe for responders [CORRECT]
● D. Request additional resources before approaching
Correct Answer: C
Rationale: Ensuring safety for responders, bystanders, and patients is the absolute first
priority when approaching any scene, as emphasized in the PHTLS XABCDE approach
where scene safety precedes patient assessment. The scene must be assessed for
hazards including traffic, fire, hazardous materials, and violence before any patient
contact can occur. When EMS personnel become victims, they not only can no longer
assist others but also add to the number of patients requiring care, potentially
overwhelming already limited resources. The walking patients (A) and motionless
,patient (B) are secondary priorities after scene safety is established. While requesting
additional resources (D) is important, it should not delay initial scene size-up and hazard
identification.
Q2. Which of the following best describes the critical thinking process in prehospital
trauma care?
● A. Following established protocols without deviation
● B. Assessing the situation, developing a plan, initiating care, reassessing, and
adjusting as conditions change [CORRECT]
● C. Transporting all patients as rapidly as possible regardless of condition
● D. Performing the same interventions on every trauma patient
Correct Answer: B
Rationale: Critical thinking in trauma care involves a dynamic, iterative process of
assessment, planning, intervention, and reassessment with ongoing adjustment based
on the patient's response, which aligns with the PHTLS principle of treating the patient
rather than rigidly following protocols. This approach recognizes that trauma patients'
conditions evolve rapidly and require continuous reevaluation and modification of the
care plan. Following protocols without deviation (A) contradicts the PHTLS emphasis on
principles over rigid protocols. Rapid transport regardless of condition (C) ignores the
need for immediate life-saving interventions, while identical interventions for all patients
(D) fails to account for individual patient needs and injury patterns.
Q3. In the absence of extenuating circumstances such as entrapment, what is the
maximum recommended on-scene time for identification and management of
immediate life threats?
● A. 5 minutes
● B. 10 minutes [CORRECT]
● C. 15 minutes
● D. 20 minutes
,Correct Answer: B
Rationale: The PHTLS guideline emphasizes minimizing on-scene time to optimize
patient outcomes within the "Golden Period" concept, targeting identification and
management of immediate life threats, patient preparation, and transport initiation
within 10 minutes of arrival. This time target balances the need for essential
interventions with the understanding that definitive care for most traumatic injuries
requires surgical intervention at a trauma center. Extended on-scene times beyond 10
minutes should only occur when absolutely necessary for extrication or when
performing critical life-saving procedures that cannot be performed during transport.
Q4. A patient has been trapped in a vehicle for approximately 30 minutes and extrication
will take another 15-20 minutes. How should this affect your approach to patient care?
● A. Delay all interventions until extrication is complete
● B. Perform only spinal immobilization until the patient is free
● C. Perform interventions in the same sequence as during the Golden Period
[CORRECT]
● D. Focus exclusively on extrication and ignore patient assessment
Correct Answer: C
Rationale: The principles of assessment and management should be applied in the
same sequence regardless of transport timing, following the XABCDE framework to
address life threats as they are identified. During extended entrapment, perform
interventions in the order they would be performed during the Golden Period—this
ensures that critical interventions for exsanguinating hemorrhage, airway obstruction, or
tension pneumothorax are not delayed by prolonged scene time. Delaying interventions
(A) or focusing only on immobilization (B) could allow treatable life threats to progress
to cardiac arrest.
Q5. During transport, your electronic monitoring devices begin producing results that
conflict with your patient's clinical condition. What is the most appropriate action?
, ● A. Treat the patient's condition based on clinical assessment, not the monitor
[CORRECT]
● B. Rely on the monitor results as they are more objective
● C. Stop all monitoring until you can recalibrate the equipment
● D. Continue transport without further assessment
Correct Answer: A
Rationale: When electronic monitoring devices produce inconsistent data, the PHTLS
principle "treat the patient, not the monitor" applies—clinical assessment findings
should guide care when they conflict with electronic monitoring. However, you should
also troubleshoot the equipment and consider potential equipment malfunction, patient
movement artifacts, or environmental interference. Relying solely on monitors (B) could
lead to inappropriate interventions, while stopping monitoring (C) removes valuable
trend data, and continuing without assessment (D) abandons the critical thinking
process entirely.
Q6. Which of the following best describes the principle of "load-and-go" versus
"stay-and-play" decision-making in trauma care?
● A. All trauma patients should receive all possible interventions on scene before
transport
● B. Patients with immediately correctable life threats should have those
addressed rapidly before transport, while those requiring complex interventions
should be transported promptly [CORRECT]
● C. Transport should never be delayed for any intervention
● D. All patients should be transported immediately without any scene
interventions
Correct Answer: B
Rationale: The load-and-go versus stay-and-play decision requires clinical judgment
based on the patient's condition, anticipated transport time, and available resources.
Immediately correctable life threats (exsanguinating hemorrhage, airway obstruction,
tension pneumothorax) should be addressed rapidly before or during transport, while
complex interventions that delay transport should be deferred. This balanced approach
