Question 1

A 7-year-old presents after a motor vehicle collision with paradoxical chest wall movement. Which injury does this indicate?

Accepted Answer

Flail chest

Answer

Flail chest results from multiple rib fractures causing a segment to move paradoxically (inward on inspiration) due to loss of chest wall integrity.

Question 2

Which finding is most consistent with Beck's triad in a pediatric trauma patient?

Accepted Answer

Hypotension, muffled heart sounds, distended neck veins

Answer

Beck's triad (hypotension, muffled heart sounds, JVD) is the classic presentation of cardiac tamponade.

Question 3

A 10-year-old with blunt abdominal trauma has a seat belt sign across the abdomen. Which organ is at highest risk for injury?

Accepted Answer

Small bowel and mesentery

Answer

A lap belt sign is strongly associated with hollow viscus injuries (small bowel/mesentery) and Chance fractures of the lumbar spine.

Question 4

When assessing circulation in a pediatric trauma patient, which is the BEST indicator of adequate perfusion?

Accepted Answer

Capillary refill time less than 2 seconds and normal mental status

Answer

Capillary refill under 2 seconds combined with normal mentation reflects adequate end-organ perfusion; BP is an unreliable early indicator in children.

Question 5

A 4-year-old with a closed femur fracture is tachycardic and pale. Estimated blood loss from a femur fracture alone can be:

Accepted Answer

Up to 500 mL

Answer

A closed femur fracture can result in up to 30–500 mL of blood loss in children, depending on age and size.
