ACLS Cardiac Arrest Exam Questions and Answers 100% Verified

What are the doses for epi? vasopressin? Amiodarone? Lidacane is used if amio is not there. Dose for lida? - ANSWER-Epi = 1mg q5min, Vasopression 40U IV, amio - not sure! Lida = 100mg What are the main steps in ACLS cardiac arrest scenarios? - ANSWER-1. Call code 2. Start CPR. 3. IV/O2/monitor 3. Check rhythm. 4. If shockable rhythm, shock. Then do another cycle of CPR. Then again rhythm check & shock, then CPR...As doing cycles of CPR there are 4 things you do on each cycle. A. Get IV or IO B. Give epi or vaso C. Give amiodarone D. address underlying causes (5Hs 5Ts) What are the 5Hs and 5Ts - ANSWER-Hypoxia, hypothermia, hypo/hyperkalemia, hypovolemia, H+ (acidosis). tension pneumo, tamponade, toxins (often TCA), thrombus DVT, thrombus PE What are shockable rhythms - ANSWER-V fib and pulseless v tach How does the algorithm change if its PEA or asystole - ANSWER-They're not shockable so don't shock them! Also there's no rhytm to adjust so don't give amio! So you go through the cycles of CPR with those exceptions and address the 5Hs 5Ts Contrast definition of PEA vs asystole - ANSWER-Asystole - no electrical and no mechanical signal. PEA - has a piddle of electrical signal :) Treatment changes from the past in terms of PEA/asystole? - ANSWER-1. Used to give atropine, now we don't. 2. Must check asystole in a second lead because if you're thinking its asystole and its really v fib that's very diff treatment What is waveform capnography and why does it matter - ANSWER-Can tell you if the person is breathing due to your CPR/tells you if CPR is effective. So normal is waves of 35-40. Cardiac arrest is flat or maybe 5mmHg CO2 and if you're providing effective CPR its 10mm Hg CO2 or more. What is a definitive airway, when do you do the airway in the algorithm - ANSWER-Definitive airway is ETT. vs LMA is not definitive but can be used. Do the airway part when giving vasopressin/epi. What is "good" CPR - ANSWER-2 mins uninterrupted, 2inches deep, 100bpm
