Question 1

A trauma patient has BP 78/50, HR 128, distended neck veins, and muffled heart sounds after a steering wheel injury. Which intervention is the priority?

Accepted Answer

Pericardiocentesis

Answer

Beck's triad (hypotension, distended neck veins, muffled heart sounds) indicates cardiac tamponade, treated emergently with pericardiocentesis.

Question 2

Which blood product ratio is recommended in damage control resuscitation for hemorrhagic shock?

Accepted Answer

1:1:1 (PRBCs:FFP:platelets)

Answer

Damage control resuscitation targets a 1:1:1 ratio of packed red blood cells, fresh frozen plasma, and platelets to approximate whole blood.

Question 3

A patient in neurogenic shock following a C5 spinal cord injury has BP 82/50 and HR 52. After fluids, BP remains low. What vasopressor is preferred?

Accepted Answer

Dopamine

Answer

Dopamine is preferred in neurogenic shock when bradycardia accompanies hypotension because it increases both heart rate and blood pressure.

Question 4

Which finding best distinguishes obstructive shock from hypovolemic shock on assessment?

Accepted Answer

Elevated JVD with hypotension

Answer

Elevated jugular venous distension (JVD) with hypotension indicates obstructive shock (e.g., tension pneumothorax, cardiac tamponade), not hypovolemic shock.

Question 5

Tranexamic acid (TXA) is most effective when administered to hemorrhagic trauma patients within what time frame?

Accepted Answer

Within 3 hours of injury

Answer

The CRASH-2 trial established TXA is most effective when given within 3 hours of injury; administration after 3 hours may increase mortality.
