TCRN TCRN Abdominal and Pelvic Trauma 2

Question 1

A trauma patient presents with a positive FAST exam showing free fluid in Morrison's pouch with hemodynamic instability. What is the most appropriate next intervention?

Accepted Answer

Emergent exploratory laparotomy

Answer

A hemodynamically unstable patient with positive FAST findings indicating intraperitoneal hemorrhage requires emergent operative intervention, not further imaging.

Question 2

Which organ is most commonly injured in blunt abdominal trauma in adults?

Accepted Answer

Spleen

Answer

The spleen is the most commonly injured solid organ in blunt abdominal trauma due to its fragility and highly vascular nature.

Question 3

A patient with a pelvic ring fracture develops hemodynamic instability despite fluid resuscitation. Pelvic binder is in place. What is the next priority intervention?

Accepted Answer

Angiographic embolization

Answer

Angiographic embolization is the preferred intervention for arterial hemorrhage from unstable pelvic fractures when a pelvic binder has not controlled bleeding.

Question 4

Which finding on abdominal CT is most indicative of a hollow viscus injury following blunt trauma?

Accepted Answer

Free intraperitoneal air

Answer

Free intraperitoneal air (pneumoperitoneum) after blunt trauma strongly suggests bowel perforation requiring surgical exploration.

Question 5

A patient sustains handlebar trauma to the abdomen. Which injury should be highest on the differential?

Accepted Answer

Duodenal injury

Answer

Handlebar injuries cause focal compression to the upper abdomen, making duodenal hematomas or perforations a classic associated injury.
