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 1 / 4

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
What are markers of tissue ischemia? - ANSWER-Lactate, pH, base deficit

What are markers of hemostasis? - ANSWER-Clotting factors and H&H
What do patients need who drop their BP after opiod administration? - ANSWER-They need volume
What system is at greatest risk following initial stabilization? - ANSWER- Pulmonary
What are hypotonic fluids? - ANSWER-Fluids that distribute throughout the body. Beneficial for dehydrated patients who need maintenance fluids.
What are isotonic fluids? - ANSWER-Fluids that fill the vascular space, for those that need circulating volume replacement. 3/4 of this fluid quickly moves to interstitial spaces
What are hypertonic fluids? - ANSWER-Fluids that helps pull fluid into the vascular space. Not good for patients at risk for fluid overload.3% Saline
What is the ratio for crystalloid replacement to blood loss? - ANSWER-3
or 4 : 1
