Question 1

In damage control resuscitation (DCR), what ratio of packed red blood cells to fresh frozen plasma is recommended?

Accepted Answer

1:1

DCR uses a 1:1 ratio of pRBC to FFP (with platelets 1:1:1) to address traumatic coagulopathy and restore all clotting factors.

Question 2

Which intervention is the priority when a trauma patient develops worsening respiratory distress after needle decompression of a tension pneumothorax?

Immediately perform a tube thoracostomy

Answer

Needle decompression is temporizing; definitive treatment is chest tube insertion, which must follow if the patient does not improve or deteriorates.

Question 3

The Revised Trauma Score (RTS) incorporates which three physiological parameters?

Accepted Answer

GCS, systolic BP, and respiratory rate

Answer

The RTS uses Glasgow Coma Scale, systolic blood pressure, and respiratory rate to quantify injury severity for triage and outcomes.

Question 4

Accepted Answer

Retroauricular ecchymosis (Battle's sign)

Answer

Battle's sign (bruising over the mastoid process) is highly specific for a basilar skull fracture involving the posterior fossa.
