Complete Solutions 2024/2025

ACLS - ANSWERS



what are the 2 ACLS coronerstones? - ANSWERS1. high quality CPR for cerebral and coronary perfusion

-continous compressions

-rate of 100-120

-compression depth of at least 2 inches with full recoil after each compression

-limit interruptions in compression



2. early defibrillation if appropriate (shockable rhythm)



what is CPR? - ANSWERSperform chest compressions and ventilate



30 compression to 2 breaths



what does it mean to debfibrillate? - ANSWERSdeliver electricity (shock( in patients without a pulse who
are in V fib or V tach



energy measured in joules



what is an advanced airway? - ANSWERSendotracheal intubation or supraglottic device



wave form capnography if available



what medications do you use in ACLS? - ANSWERS1. epinephrine 1 mg (IV/IO)- vasoconstricts

,2. amiodarone (IV/IO)- class 3 antiarrhythmic used for V fib and V tach



what is return of spontaneous rhythm (ROSC)? - ANSWERSpalpable pulse at *central* sites
(carotid/femoral)



NOT RADIAL



abrupt increase in end-tidal CO2 (greater than 40 mmHg)



what is V fib? - ANSWERSasynchronous pattern of ventricular depolarization and repolarization



no cardiac output



heart "quivers"



what are the causes of V fib? - ANSWERS1. ischemic myocardium



2. untreated V tach



3. drug effect/electrolytes/acid base disorders



what is pulseless ventricular tachycardia (pVT) - ANSWERSdecreased impulse conduction around areas of
injury



what will you see on EKG of pVT? - ANSWERSwide QRS complex (wide complex tachycardia)



what will the rate be for pVT? - ANSWERSbetween 120-250



what does pVT normally present as? - ANSWERSpresents with a pulse and then becomes unstable

,what does monomorphic mean? polymorphic? - ANSWERSmonomorphic: same shape in every QRS
complex



polymorphic: different shapes in every QRS complex (torsades de pointes)



what are the causes of pVT? - ANSWERSischemia, heart failure, drugs/electrolytes/acid base disorders



what is the first thing you should do if you see VF/pVT? - ANSWERS*start CPR*



then: shock, resume CPR, establish IV/IO access, pulse check, shock again, admin epi



what is asystole? - ANSWERSno ventricular activity seen with a possible occasional P wave present



"flate line"



what are the causes of asystole? - ANSWERS1. ischemia

2. hypoxia

3. post defibrillation myocardial "stunning"

4. end of life



What is pulseless electrical activity? - ANSWERSorganized electrical pattern without cardiac contraction



any organized activity in a patient without a pulse other than VF/pVT



may have narrow or wise QRS complexes with fast or slow rates



*may look like normal sinus rhythm*

, CHECK THE PULSE



what are the causes of PEA - ANSWERSHUGGGEEE

ACLS includes a set of differentials called H's and T's



what are the H's? - ANSWERSHypovolemia



Hypoxia



hydrogen Ion (acidosis)



hypo/hyperkalimia



Hypothermia



what are the T's? - ANSWERSTension pneumothorax



tamponade- cardiac



toxins



thrombosis-coronary



thrombosis- PE



what should you do if you see a patient in asystole or PEA? - ANSWERS1. start CPR



2. establish IV/IO access
