  1. A patient presents with Beck's triad (hypotension, muffled heart sounds, jugular venous distension). Which type of shock does this suggest?

    Answer: Obstructive shock from cardiac tamponade

    Beck's triad is pathognomonic for cardiac tamponade, which causes obstructive shock by preventing adequate ventricular filling.

  2. Which hemodynamic profile is characteristic of distributive (septic) shock?

    Answer: High CO, low SVR, low MAP

    Septic shock is characterized by high cardiac output from tachycardia, low systemic vascular resistance from vasodilation, and resultant low MAP.

  3. A trauma patient with suspected hemorrhagic shock is unresponsive to 2L of crystalloid. What resuscitation strategy is preferred in modern flight medicine?

    Answer: 1:1:1 ratio of packed red cells, fresh frozen plasma, and platelets

    Damage control resuscitation using a 1:1:1 ratio of pRBC:FFP:platelets is the evidence-based approach for hemorrhagic shock to restore coagulation factors alongside volume.

  4. In neurogenic shock following spinal cord injury, which hemodynamic combination is expected?

    Answer: Hypotension with bradycardia

    Neurogenic shock presents with hypotension and paradoxical bradycardia due to loss of sympathetic tone below the injury level with intact vagal activity.

  5. When treating refractory septic shock with vasopressors, which agent is the FIRST-LINE choice per Surviving Sepsis guidelines?

    Answer: Norepinephrine

    Norepinephrine is the first-line vasopressor for septic shock, providing potent alpha-mediated vasoconstriction with moderate beta-1 effects to raise MAP.

  6. A patient in hypovolemic shock has a systolic BP of 70 mmHg and is not responding to initial fluid resuscitation. What permissive hypotension target is acceptable in penetrating trauma without TBI?

    Answer: Systolic BP 80-90 mmHg

    Permissive hypotension targeting a systolic BP of 80-90 mmHg reduces ongoing hemorrhage and dilutional coagulopathy in penetrating trauma without TBI.
