A+
-harpy - CORRECT ANSWER: surgical repair
"HAT" menumonic - CORRECT ANSWER: for quick SOFA score (sequential organ
failure assessment)
SBP under 100
AMS
tachypnea over 22
HAT = hypotension, AMS, tachypnea
% blood loss that is tolerable versus not tolerable - CORRECT ANSWER: most people
can tolerate a 10% blood volume loss but most can't tolerate 40%
% of skull contents - CORRECT ANSWER: 80% brian, blood 10%, CSF 10%
*CSF is displaced first, blood next (not good when blood leaves the brain --patient is in
trouble)
% types of skull fractures - CORRECT ANSWER: 80% are nondisplaced
20% depressed skull fracture
+2 adjacent rib fractures - CORRECT ANSWER: flail chest
1st question to ask in any traumatic injury? - CORRECT ANSWER: what was the dose
of energy involved?
(was it high or low?)
,2 physiological mechanisms in rhabdo - CORRECT ANSWER: direct injury to the
cells(crush/tear/burn/poision/dissolution)
muscle cell hypoxia - ATP depletion
**any prolonged anaerobic condition will disrupt the Na-K pump
injury to cell membrane deep tissue infection temperature extremes
(frostbite/burn/lightening) cellular energy depletion like physical exertion, rx induced
delirium, dangrugs/toxins/venum like snake bites
2 problems in traumatic bvleeding - CORRECT ANSWER: anatomica problem =
mechanical bleeding. stop/plug holes then replace volume
coagulpathy bleeding: physicaologica bleeding. can't fix int eh OR. needs goal directed
treatment
2 q's to ask in GSW - CORRECT ANSWER: caliber
type of gun
# of entrance/exit wounds
high/low velocity
2 types of shock related to SCI - CORRECT ANSWER: neurogenic shock
spinal shock
**occur at the same time but spinal shock resolves first
2 word description for neurogenic shock - CORRECT ANSWER: relative hypoperfusion
3 categories of structures involved in TBI - CORRECT ANSWER: bony (oath), spinal
cord (neuro), associated structures
,3 layers of blood vessels - CORRECT ANSWER: endothelium (tunica intima)
tunica media
tunica adventitia
3 patient populations who are vulnerable to subdural hematomas - CORRECT
ANSWER: infants, geriatric, alcoholics
*fall, bump,
*Geriatric/alcoholics = neuronal atrophy (brain shrink), anticoagulated strate from liver
damage
3 q's to ask with falls - CORRECT ANSWER: AO x __
on thinners
mechanical verus medicinal
"did the fall happen then LOC or LOC which led to the fall?
3 questions to ask in trauma - CORRECT ANSWER: -what was the dose of energy?
-where did it go?
-what injuries are likely?
3 types of patients who need hyPOtonic IVF - CORRECT ANSWER: hydrate,
maintenance, dehydration
increase glucose/Na, GI losses
3L of NS or LR - CORRECT ANSWER: stays in the extracellular space and doesn't
enter the cells
*3L of isotonic crystallizes increase circulating volume by 3 cups. the rest (2250ml) goes
between the cells so increases isotonic VIF. puff up fluid between cells makes it more
difficult lt to get fluid to the cells
*healthy individuals n red 3:1 or 4:1 replacement of IVF per blood loss
, more needed to replace if shock/septic
4 incomplete SCI syndromes - CORRECT ANSWER: anterior
posterior
central
Brown-Sequard
72hr long local anesthetic added to the surgical site - CORRECT ANSWER: Exparel
A&P of the skull - CORRECT ANSWER: remember = it is an enclosed box
abd cavity & blood volume capacity - CORRECT ANSWER: abdomen cavity has
enough space to hold the entire blood volume
abdominal injury most common in truma - CORRECT ANSWER: spleen
abdominal pressure that is irreversible tissue injury - CORRECT ANSWER: normal is 2 -
8mm hg
20 - 30mmgh causes significant injury
added to blood products that may cause low Ca - CORRECT ANSWER: citrate.
adult blood volume - CORRECT ANSWER: 4-6L
adverse effect of intra-abdominal HTN - CORRECT ANSWER: cardiac
poor perfusion
hepatic congestion
