The PHTLS meaning goes beyond a simple acronym; it represents a commitment to excellence in trauma care. The Prehospital Trauma Life Support course integrates the latest evidence-based medical knowledge, including the XABCDE assessment approach, to improve patient outcomes in emergency situations.

PHTLS Exam at a Glance

What changed for PHTLS in 2026

• Oct 27, 2026: Retake policy changed to One re-test within 30 days using the same written evaluation tool (previously One re-test within 30 days; same written test).^[2]
• Oct 27, 2026: Eligibility (Provider Course) changed to EMS practitioners, nurses, physician assistants, physicians, and other prehospital practitioners (previously EMS practitioners, nurses, PAs, physicians and other prehospital practitioners).^[3]

According to National Association of Emergency Medical Technicians, “The mission of PHTLS is to promote excellence in trauma patient management by all providers involved in the delivery of prehospital care through global education.”^[4]

Worked examples: how to reason through PHTLS questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: You are treating a patient with extensive full-thickness burns to the face and neck after being pulled from a house fire. The patient has a hoarse voice, carbonaceous sputum, and singed nasal hairs. What is the highest priority intervention?

1. Applying cool, moist sterile dressings to the facial burns.
2. Calculating the Total Body Surface Area (TBSA) to guide fluid resuscitation.
3. Anticipating the need for a definitive airway and preparing for early intubation.
4. Obtaining intravenous access for immediate pain management.

Answer: C. Anticipating the need for a definitive airway and preparing for early intubation.

Explanation:

A hoarse voice, carbonaceous sputum and singed nasal hairs after a house fire all point to inhalation injury. The airway can swell quickly, and once it does, intubation becomes much harder or impossible. That is why anticipating a definitive airway and preparing for early intubation (C) is the priority. Cool, moist dressings (A) treat the skin, not the threat to life, and cooling large burns risks hypothermia. Calculating TBSA (B) guides fluid resuscitation later, but it does nothing for an airway that may be closing. IV access for pain control (D) matters, but it comes after the airway is protected.

Rule to remember: in a burn patient, signs of inhalation injury put the airway at the top of the list. Act on the warning signs before swelling makes intubation impossible.

Example 2

Question: What does the 'X' in the PHTLS XABCDE patient assessment mnemonic represent?

1. External examination of the body surface
2. eXsanguinating hemorrhage requiring immediate control
3. Extremity assessment for fractures
4. Exposure and environment

Answer: B. eXsanguinating hemorrhage requiring immediate control

Explanation:

The X stands for eXsanguinating hemorrhage (B). PHTLS puts it before the airway because a patient with massive external bleeding can die of blood loss within minutes, faster than most airway problems. In practice, a tourniquet or direct pressure on a life-threatening bleed comes before opening the airway or happens at the same time. External examination of the body surface (A) is not a step in the mnemonic. Assessing extremities for fractures (C) belongs to the secondary survey unless a limb is bleeding heavily. Exposure and environment (D) is the E at the end, where you undress the patient to find injuries and then prevent heat loss.

Rule to remember: stop major bleeding you can see, then move through A, B, C, D and E.

Example 3

Question: You arrive on scene to find an unresponsive trauma patient with gurgling sounds coming from their airway. What is the MOST appropriate initial action?

1. Perform immediate suctioning of the oropharynx.
2. Insert an oropharyngeal airway (OPA).
3. Apply a non-rebreather mask at 15 L/min.
4. Log-roll the patient onto their side.

Answer: A. Perform immediate suctioning of the oropharynx.

Explanation:

Gurgling means liquid (blood, vomit or secretions) is sitting in the upper airway, so suctioning the oropharynx (A) comes before anything else. Nothing else works while the airway is full of fluid. An OPA (B) keeps the tongue off the back of the throat, but it does not clear fluid and can push material deeper. A non-rebreather mask (C) sends oxygen into an airway that is still blocked, so little of it reaches the lungs. Log-rolling the patient onto their side (D) can help fluid drain when no suction is available. When suction is at hand, it is the faster and more direct fix.

Rule to remember: listen to the airway. Gurgling means suction. Snoring means repositioning or an airway adjunct.

How to use these practice tests

Start with the official course material. PHTLS is a course with a written evaluation and a scenario evaluation, not a standalone exam. Your instructor's material is the main source, so do any assigned reading or online modules before the classroom days. This matters most for the hybrid format, where 8 hours of instruction are online.

Find your weak topics. Take the PHTLS Pre & Post Questions to see where you stand. Then work on the topics you missed, starting with the assessment sequence: XABCDE primary survey, shock and hemorrhage control and airway and ventilation.

Move on to the systems and special groups. Next, cover thoracic, brain, spinal and abdominal and pelvic trauma. Then do pediatric, geriatric, burns and environmental cases.

Say your reasoning out loud. For every miss, read the explanation and say why each wrong option is wrong. Scenario stations test the same thinking, spoken aloud in order.

Finish with a mixed set. In the final days, take the PHTLS Knowledge Questions as a mixed review. If you don't pass a component, you get a re-test within 30 days, so plan to review that area right away.

Expect to invest between $300 and $400 total for your PHTLS certification, including the PHTLS course fee and textbook. Employers often reimburse these costs.
