A trauma patient has hypotension, distended neck veins, and muffled heart sounds. Most likely diagnosis?
Answer: Cardiac tamponade
Beck's triad: hypotension, JVD, and muffled heart sounds is the classic presentation of cardiac tamponade.
Which shock type is characterized by hypotension, bradycardia, and warm flushed skin below the injury?
Answer: Neurogenic shock
Neurogenic shock results from loss of sympathetic tone after spinal cord injury, causing vasodilation and bradycardia.
In massive transfusion protocol, what is the recommended PRBC:FFP:Platelets ratio?
Answer: 1:1:1
A balanced 1:1:1 ratio mimics whole blood and prevents dilutional coagulopathy.
A 25-year-old with a left chest stab wound develops PEA in the trauma bay. What is the most appropriate intervention?
Answer: Emergency department thoracotomy
PEA from penetrating thoracic trauma is an indication for ED thoracotomy.
What is the earliest and most reliable clinical indicator of adequate resuscitation?
Answer: Urine output of 0.5 mL/kg/hour
Urine output (0.5 mL/kg/hr adults) is the most reliable indicator of end-organ perfusion.
Permissive hypotension targets what systolic BP in a patient without TBI?
Answer: 80-90 mmHg
Target SBP 80-90 mmHg to avoid disrupting clot formation while maintaining organ perfusion.
