This comprehensive practice exam is designed based on the PHTLS 10th Edition guidelines
(the current gold standard for 2024–2027). It focuses on the X-A-B-C-D-E assessment
methodology, updated TBI management protocols, and refined fluid resuscitation strategies.

Section 1: Trauma Assessment & Management
1. What is the first priority when arriving at the scene of a traumatic injury?
• Answer: Scene Safety.
• Rationale: The safety of the provider is paramount; you cannot help the patient if you
become a casualty yourself.
2. According to the PHTLS 10th Edition, what is the correct order of the primary survey?
• Answer: X-A-B-C-D-E.
• Rationale: "X" stands for Exsanguinating Hemorrhage. Life-threatening external
bleeding must be addressed before the airway, as a patient can bleed out faster than they
can suffocate.
3. In the "X" portion of the assessment, what is the preferred method for controlling life-
threatening extremity hemorrhage?
, • Answer: Windlass Tourniquet.
• Rationale: Tourniquets are the gold standard for rapid control of arterial bleeding in
extremities.
4. What does the "E" in XABCDE stand for?
• Answer: Exposure and Environment.
• Rationale: The patient must be undressed to find all injuries, but then immediately
covered to prevent hypothermia (the "lethal triad" component).
5. Which of the following is a component of the "Lethal Triad" in trauma?
• Answer: Coagulopathy, Acidosis, and Hypothermia.
• Rationale: These three conditions exacerbate each other, leading to a high mortality rate
in trauma patients.
(Questions 6–20 follow this logic, focusing on scene size-up, mechanism of injury (MOI), and the
"Golden Period" concept.)
Section 2: Airway and Ventilation
21. What is the preferred method for opening the airway of a trauma patient with a
suspected spinal injury?
• Answer: Jaw-Thrust Maneuver.
• Rationale: This minimizes movement of the cervical spine compared to the head-
tilt/chin-lift.
22. When should an Oropharyngeal Airway (OPA) be used?
• Answer: Only in unconscious patients without a gag reflex.
• Rationale: Using an OPA in a conscious or semiconscious patient can induce vomiting
and aspiration.
23. What is the target End-Tidal CO2 (EtCO2) for a patient with a traumatic brain injury
(TBI) who is not herniating?
• Answer: 35–45 mmHg.
• Rationale: Maintaining normal CO2 levels prevents unnecessary cerebral
vasoconstriction or vasodilation.
