  1. Which landmark is used to perform an emergency intraosseous (IO) insertion at the proximal tibia?

    Answer: 2 cm below the tibial tuberosity on the anteromedial surface

    The proximal tibial IO site is 2 cm below the tibial tuberosity on the flat anteromedial surface of the tibia, away from the growth plate.

  2. What is the first action when a combat casualty goes into cardiac arrest due to non-traumatic causes (e.g., heat stroke)?

    Answer: Begin CPR immediately

    For non-traumatic cardiac arrest, standard CPR (chest compressions and ventilations) should begin immediately according to TCCC guidelines.

  3. What condition is indicated by absent breath sounds unilaterally, hypotension, and distended neck veins in a mechanically ventilated casualty?

    Answer: Tension pneumothorax

    The triad of absent unilateral breath sounds, hypotension, and JVD in a ventilated patient is the classic presentation of tension pneumothorax.

  4. A casualty presents with Beck's Triad (hypotension, muffled heart sounds, JVD) after a penetrating chest wound. What injury should you suspect?

    Answer: Cardiac tamponade

    Beck's Triad — hypotension, muffled heart sounds, and jugular vein distension — is the classic presentation of cardiac tamponade caused by blood in the pericardial sac.

  5. When treating a combat casualty for hypothermia prevention, at what core body temperature does severe hypothermia (risk of cardiac arrhythmia) begin?

    Answer: Below 30°C (86°F)

    Severe hypothermia is defined as a core temperature below 30°C (86°F), at which ventricular fibrillation and other life-threatening arrhythmias become likely.

  6. What is the recommended method for assessing a casualty's level of consciousness (LOC) rapidly in the field?

    Answer: AVPU scale (Alert, Voice, Pain, Unresponsive)

    The AVPU scale is the rapid field assessment tool for LOC; the full GCS is used in more controlled settings and requires more time to complete.

  7. A casualty with a suspected spinal injury needs to be moved due to incoming fire. What is the correct TCCC approach?

    Answer: Move the casualty using a hasty drag while keeping the spine as straight as possible; tactical situation takes priority

    TCCC prioritizes removing the casualty from danger; spinal precautions are maintained as feasibly as possible, but tactical necessity overrides rigid spinal immobilization protocols.
