Trauma Flashcards
Which intracranial hemorrhage is associated with a LOC, followed by a lucid interval, then a rapid decline in mental status?
Epidural Hematoma
Which intracranial hemorrhage is the most common and is associated with slower onset of symptoms and be classified as acute (14 days)?
Subdural Hematoma
Which intracranial hemorrhage is associated with bleeding within the brain tissue itself and signs/symptoms depend on which area of the brain is affected, often manifests like a stroke?
Intracerebral Hematoma
Which intracranial hemorrhage is associated with pupil dilation on side of injury, severe headache, decreasing LOC, and a stiff neck?
Subarachnoid Hemorrhage
What is the most important factor for Newton’s law of kinetic energy?
Velocity
What is the difference between compensated and decompensated shock?
Drop in blood pressure
What is the most prominent symptom of compartment syndrome?
Pain out of proportion
How does neurogenic shock disrupt the brains ability to compensate?
Interruptions in CNS limits vasoconstriction allowing dilation.
What is it called when there is a 10-15 Hg drop in BP during inhalation?
Pulsus Paradoxus
What is the Parkland Formula?
4mL x TBSA x weight in kg, 1st half in 1st 8 hrs

3mL for every mL
How much blood does the average adult have?
5mL
What are the 4 classes of hemorrhagic shock?
Class I- 30% (1500mL)
Class IV- >40% (2000mL)
What is another name for Class II shock and what are the signs?
Compensated Shock
HR>100, BP maintained, tachypnic at 20-30, anxiety, narrowing pulse pressure
What is another name for Class III shock and what are the signs?
Decompensated Shock
HR>120, hypotension, tachypnic at 30-40, anxiety/confusion
