GUARANTEED SUCCESS
Updated 2026 Questions and Answers | 100% Verified
Exam Prep and Comprehensive Rationales Included
,atrial flutter
premature atrial contractions
1st Degree AV Block
2nd Degree AV Block Type 1
2nd Degree AV Block Type 2
3rd Degree AV Block
paroxysmal supraventricular tachycardia
bundle branch block
premature ventricular contraction
,ventricular tachycardia
ventricular fibrillation
torsades de pointes
agonal
defibrillators electrical shocks to completely depolarize all cardiac cells to eliminate
bad/pathologic rhythms and let correct rhythm restart
monophasic defibrillation one shock at a higher amount of joules
biphasic defibrillation shock sent one way and then returned immediately
- uses a smaller amount of energy
external defibrillator manual: staff programs and pushes "fire" button
automatic: AED does all the thinking
manual defibrillation - RN do not delay defibrillation to obtain IV access or intubate
place pads firmly
turn on defibrillator and make sure connections are secure
set energy to 120-200J for biphasic
announce "clear"
press "fire"
post shock: CPR for 2 mins then check rhythm and pulse
anterior/posterior placement one pad on L chest
one pad on L back
, sternal/lateral placement one pad on R chest
one pad on L side
external wearable defibrillator AED incorporated into vest, usually temporary
external wearable defibrillator - pt teaching must wear vest at all times
change battery daily
charge second battery daily
attend to tones/vibrations
internal cardiac defibrillators fully implanted battery-operated device designed to recognize and
terminate/shock dysrhythmias that cause SCD w/ electrical countershocks
internal cardiac defibrillators - uses defibrillation
pacing
cardioversion
storing data
being programmed
being combined with pacemaker
internal cardiac defibrillators - morbidity 30-50% 2 year mortality after SCD without ICD
2% year mortality after SCD with ICD
internal cardiac defibrillator - indications spontaneous sustained v tach/fib that can't be well controlled
v tach/fib in noncompliant pts
internal cardiac defibrillators - non-indications sustained v tach/fib caused by:
- ischemia
- infarction
- metabolic problems
that can be corrected or reversed
internal cardiac defibrillators - contraindications prophylactic use
extensive anterior MI not tx w/ thrombolytics
recurrent syncope MI
children congenital long QT syndrome
cardioversion small shocks/miniature difibrillation (50-100J)
unsynchronized cardioversion use when not able to synchronize such as with irregular rhythms
