A casualty sustains a blast injury with suspected traumatic brain injury (TBI) AND hemorrhagic shock. What is the target systolic blood pressure for resuscitation?
Answer: 110 mmHg or higher
With suspected TBI, the target systolic BP is 110 mmHg or greater to maintain cerebral perfusion pressure and prevent secondary brain injury.
What is the correct sequence for applying a junctional tourniquet (e.g., SAM JT) to control groin hemorrhage?
Answer: Position over femoral triangle, tighten until bleeding stops, secure strap
A junctional tourniquet is positioned over the femoral triangle, tightened to occlude the femoral artery until bleeding ceases, then secured.
Which of the following is NOT an indication for performing a surgical cricothyrotomy in TCCC?
Answer: Casualty is responsive and speaking clearly
A casualty who is speaking clearly has a patent airway and does not need surgical airway intervention.
What is the primary purpose of administering tranexamic acid (TXA) in combat casualties?
Answer: To inhibit fibrinolysis and preserve clot formation
TXA inhibits fibrinolysis (the breakdown of clots), helping casualties who are at risk of traumatic coagulopathy retain their ability to form blood clots.
Within what time window must TXA (tranexamic acid) be administered to be effective in a trauma casualty?
Answer: Within 3 hours of injury
TXA must be given within 3 hours of injury; administration after 3 hours has been shown to increase mortality rather than decrease it.
How should a hypothermic combat casualty be managed in Tactical Evacuation Care (TACEVAC)?
Answer: Remove wet clothing, apply heat packs to the axillae and groin, cover with a hypothermia wrap
Preventing and treating hypothermia involves removing wet clothing, applying chemical heat packs to high-blood-flow areas, and wrapping the casualty in an insulating layer.
A casualty has an open eye injury with visible uveal tissue prolapse. What is the correct field management?
Answer: Cover the eye with a rigid shield without pressure and do not remove any protruding tissue
An open globe injury requires a rigid eye shield (not pressure) to protect the eye; applying pressure can force intraocular contents out and cause permanent blindness.
