In damage control resuscitation (DCR), what ratio of packed red blood cells to fresh frozen plasma is recommended?
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.
Which intervention is the priority when a trauma patient develops worsening respiratory distress after needle decompression of a tension pneumothorax?
Answer: Immediately perform a tube thoracostomy
Needle decompression is temporizing; definitive treatment is chest tube insertion, which must follow if the patient does not improve or deteriorates.
The Revised Trauma Score (RTS) incorporates which three physiological parameters?
Answer: GCS, systolic BP, and respiratory rate
The RTS uses Glasgow Coma Scale, systolic blood pressure, and respiratory rate to quantify injury severity for triage and outcomes.
Which sign is most specific for a basilar skull fracture in a trauma patient?
Answer: Retroauricular ecchymosis (Battle's sign)
Battle's sign (bruising over the mastoid process) is highly specific for a basilar skull fracture involving the posterior fossa.
A patient involved in a high-speed crash presents with left flank pain and gross hematuria. CT shows a Grade III renal laceration. What is the typical management?
Answer: Nonoperative management with close monitoring
Grade I–III renal lacerations in hemodynamically stable patients are typically managed nonoperatively with serial imaging and monitoring.
What is the primary concern with administering high-volume crystalloid resuscitation in hemorrhagic shock?
Answer: Dilutional coagulopathy and worsening of the lethal triad
Large-volume crystalloid worsens the lethal triad (hypothermia, acidosis, coagulopathy) by diluting clotting factors and promoting hypothermia.
During a trauma resuscitation, a patient's SpO2 drops to 84% despite high-flow O2 via non-rebreather mask. What is the nurse's priority action?
Answer: Prepare for definitive airway management
Persistent hypoxia despite supplemental O2 indicates the need for definitive airway management (endotracheal intubation) to secure and protect the airway.
