AEMCA Trauma and Shock Management 3

Question 1

Which fluid resuscitation strategy is currently recommended for hemorrhagic shock in penetrating trauma to prevent worsening coagulopathy?

Accepted Answer

Permissive hypotension with limited crystalloid

Answer

Permissive hypotension (targeting SBP ~80–90 mmHg) with limited crystalloid minimizes dilutional coagulopathy and clot disruption until surgical control.

Question 2

A cyclist struck by a car has a closed femur fracture. Approximately how much blood can be lost into the thigh from this injury?

Accepted Answer

Up to 1,500 mL

Answer

A closed femur fracture can conceal up to 1,000–1,500 mL of blood within the thigh compartment, contributing significantly to hypovolemic shock.

Question 3

Which assessment finding best differentiates cardiogenic shock from hypovolemic shock in a trauma patient?

Accepted Answer

Jugular venous distension with pulmonary edema

Answer

Cardiogenic shock causes fluid backup, presenting with JVD and pulmonary edema, while hypovolemic shock presents with flat neck veins and no pulmonary edema.

Question 4

You are packaging a patient with a suspected pelvic fracture and hemodynamic instability. What prehospital intervention is most appropriate?

Accepted Answer

Apply a pelvic binder at the level of the greater trochanters

Answer

A circumferential pelvic binder at the greater trochanters reduces pelvic volume and tamponades venous hemorrhage from an unstable pelvic fracture.

Question 5

When using the Revised Trauma Score (RTS) to triage patients, which three parameters are assessed?

Accepted Answer

Glasgow Coma Scale, systolic BP, respiratory rate

Answer

The Revised Trauma Score uses GCS, systolic blood pressure, and respiratory rate to predict survival and guide triage decisions.
