KAISER EKG COMPREHENSIVE QUESTIONS AND
ANSWERS SET A+
✔✔how to treat non-symptomatic and wide tachycardia - ✔✔adenosine )if regular and
monomorphic), antiarrhythmic infusion, expert consultation
✔✔the ability of muscle cells to respond to outside stimulus - ✔✔excitability
✔✔the ability to receive an electrical stimulus and conduct that impulse to adjacent
cells, all cardia cells possess this - ✔✔conductivity
✔✔the process where cardiac cells shorten, causing muscular contraction in response
to an electrical stimulus - ✔✔contraction
✔✔ventricular repolariztion - ✔✔T wave
✔✔rate of atrial fibrillation - ✔✔350-400 bpm
✔✔what two electrolyte imbalances may cause ventricular tachycardia -
✔✔hypokalemia
hypomagnesemia
✔✔what electrolyte abnormality may cause sinus brady - ✔✔hyperkalemia
✔✔increased intracranial pressure may cause what heart rhythm - ✔✔sinus brady
✔✔what are the two non-shockable rhythms - ✔✔1. asystole
2. PEA
✔✔ if we have too long of ventricular repolarization this may lead to - ✔✔Vtach and Vfib
, ✔✔ventricular repolarization is represented by - ✔✔T wave
✔✔ventricular depolarization is represented by - ✔✔qrs complex
✔✔to measure the QT interval you measure what - ✔✔the initiation of the QRS to the
end of T wave
✔✔where do you look on the ekg to see if there are abnormalities in ventricular
repolarization - ✔✔QT interval
✔✔QT interval that is too long represents - ✔✔delay in ventricular repolarization
✔✔if there is a a wide QRS complex what can we say about the bundles - ✔✔there is a
delay in one of the bundles
✔✔the ekg shape that looks like bunny ears - ✔✔right bundle branch block
✔✔electrolyte abnormalities that may cause a long QT - ✔✔hypokalemia
hypocalcemia
hypomagnesemia
✔✔When we must shock a pt for afib or tachy what is our emergency intervention -
✔✔synchronized cardioversion on the R wave
✔✔no SAD node firing for a big pause, then begins to fire again resulting in no P wave
during this event but the PR interval remains normal - ✔✔sinus pause or sinus arrest
✔✔long term tx for pt with afib or aflutter - ✔✔blood thinners
✔✔this med may possibly cause a 1st degree heart block - ✔✔dilitiazem
✔✔medication that will help get a pt out of Afib - ✔✔amiodarone
✔✔4 SVT interventions - ✔✔O2, vagal maneuvers, Adenosine, synchronized
cardioversion
✔✔3 interetions for idioventricular rhythms - ✔✔pacers, vasopressor meds like
dopamine and beta agonist,
✔✔a pt who has idioventricular rhythm but is pulseess needs what intervention -
✔✔CPR and code Blue
