QUESTIONS WITH DETAILED
VERIFIED ANSWERS (100%
CORRECT ANSWERS) /ALREADY
GRADED A+
What chamber of the heart is most commoly injured
in blunt trauma? - ....ANSWER...RV because the heart
is rotated to the left
Majority of injuires are myocardial contusions
What is pericardial tamponade? -
....ANSWER...Occurs when fluid accumulates in the
pericardial sac, as volume in the sac increases,
volume in the chambers decreases.
Temporarily overcome this by aggressive preload.
Emergent surgical repair is the preferred treatment.
Will see a narrow pulse pressure
,What test can be used to screen for thoracic aortic
disruption? - ....ANSWER...Checking the BP in both
arms, normally there should be less than 12 mHg
difference in SBP between the arms.
Avoid HTN to limit further dissection & avoid rupture
What is permissive hypotension? -
....ANSWER...Keeping SBP 80-90
Aggressvie fluid resuscitation disrupts new clots,
dilutes blood, promotes coagulopathies, and
aggravates endothelial leakage
NOT APPRORIATE FOR TBI
What are the 2 types of bleeding in a trauma patient?
- ....ANSWER...Mechanical & Coagulopathic
Mechanical requires surgery to fix hole
Coagulopathic- later in ICU,
TIC-trauma induced coagulopathy
What are the suggested lab studies for someone in
Trauma induced cogulaopthy? -
....ANSWER...Thromboelastography (TEG)
,Rotational Thromobelastometry (ROTEM)
both testes provide real-time visual representation
of clot formation and clot lysis
Why is autotransfused blood better than banked
blood? - ....ANSWER...It is fresher, warmer, releases
O2 better, and costs less
Banked blood causes what electrolyte
abnormalities? - ....ANSWER...Elevated K-released
from old or damaged blood cells
Decreased Ca-citrate in blood binds with calcium so
the ionized Ca level is low
What nursing assessment would make you suspet
low calcium? - ....ANSWER...Carpal spasm
(Trousseau Sign) while checking BP
What does SBP estimate for you? -
....ANSWER...SBP= CO--they go up & down together
It is an indication of volume (preload) and
contractility
, What does DBP estimate for you? - ....ANSWER...DBP
is a measure of vascular resistance-afterload
DBP reflects vasoconstriction due to sympathetic
compensation
What is pulse pressure? - ....ANSWER...The
relationship between CO & the body's compensatory
vasoconstrictive response
Pulse Pressure= SBP-DBP
Minimal acceptable number is 30-40 or
25% of SBP
What is MAP, and how is it calculated? -
....ANSWER...It is the organ & tissue perfusion
pressure, the pressure the organs actually receive.
Normal is >65.
SBP+DBPx2/3
What is shock index? - ....ANSWER...The relationship
between SBP & heart rate required to maintain it
(tachycardic compensation). HR divided by SBP,
normal is 0.5-0.7
