Question 1

A casualty sustains a blast injury with suspected traumatic brain injury (TBI) AND hemorrhagic shock. What is the target systolic blood pressure for resuscitation?

Accepted Answer

110 mmHg or higher

Answer

With suspected TBI, the target systolic BP is 110 mmHg or greater to maintain cerebral perfusion pressure and prevent secondary brain injury.

Question 2

What is the correct sequence for applying a junctional tourniquet (e.g., SAM JT) to control groin hemorrhage?

Accepted Answer

Position over femoral triangle, tighten until bleeding stops, secure strap

Answer

A junctional tourniquet is positioned over the femoral triangle, tightened to occlude the femoral artery until bleeding ceases, then secured.

Question 3

Which of the following is NOT an indication for performing a surgical cricothyrotomy in TCCC?

Accepted Answer

Casualty is responsive and speaking clearly

Answer

A casualty who is speaking clearly has a patent airway and does not need surgical airway intervention.

Question 4

What is the primary purpose of administering tranexamic acid (TXA) in combat casualties?

Accepted Answer

To inhibit fibrinolysis and preserve clot formation

Answer

TXA inhibits fibrinolysis (the breakdown of clots), helping casualties who are at risk of traumatic coagulopathy retain their ability to form blood clots.

Question 5

Within what time window must TXA (tranexamic acid) be administered to be effective in a trauma casualty?

Accepted Answer

Within 3 hours of injury

Answer

TXA must be given within 3 hours of injury; administration after 3 hours has been shown to increase mortality rather than decrease it.
