2024 BASIC DYSRHYTHMIAS EXAM2 WITH CORRECT ANSWERS
what do you do if artifacts occur on an ECG? - CORRECT-ANSWERScheck
connections in equipment
rhythm starts in the SA node, 60-100 BPM, normal conduction pathway -
CORRECT-ANSWERSnormal sinus rhythm
normal P wave length - CORRECT-ANSWERS.06-.20
the time of passive of impulse through the atria, causing atrial depolarization
(atrial contraction) - CORRECT-ANSWERSP wave
normal PR interval length - CORRECT-ANSWERS.12-.20
when is defibrillation appropriate? - CORRECT-ANSWERSVF, pulseless VT
where are paddles placed for defibrillation? - CORRECT-ANSWERSfront/back;
R upper sternum under clavicle and left of left nipple at mid-ax line
if the pt is _______ toxic, you cannot defibrillate because it can cause
_____________ - CORRECT-ANSWERSdigitalis, ventricular arrhythmias
used only if the pt is very tachycardic and symptomatic: hypotensive, chest
pain, meds ineffective; converts the heart back to normal sinus rhythm. may
not be emergent.
delivers a shock on R wave. - CORRECT-ANSWERSsynchronized cardioversion
you're performing synchronized cardioversion and the pt becomes pulseless
or goes into VF. what do you do? - CORRECT-ANSWERSstop, switch to
defibrillation
________ pacemakers sense activity of the heart and only fire when the HR
drops. preferable. - CORRECT-ANSWERSdemand
_________ pacemakers stimulate the ventricles in order to end tachycardia -
CORRECT-ANSWERSantitachycardia
, pacemaker implanted into the body. implicated for AV block, a-fib, bundle
branch block, cardiomypotahy, HF, SA node dysfunction, tachydysrhythmias.
- CORRECT-ANSWERSpermanent
pacemaker attached to outer power source. indicated for HR and rhythm
maintenance during surgery/postop, prophylaxis post-open heart surgery,
acute anterior MI with AV block, acute inferior MI with symptomatic
bradycardia and AV block - CORRECT-ANSWERStemporary
the pacemaker fails to recognize spontaneous atrial/ventricular activity and
fires inappropriately
pt at risk for VT - CORRECT-ANSWERSfailure to sense
the pacemaker has insufficient electrical charge to produce atrial or
ventricular contraction of the heart.
at risk for bradycardia or asystole
a spike without the wave after it - CORRECT-ANSWERSfailure to capture
you know a pacemaker is _________ (single/double) chamber paced if there is
a spike before the P wave (atrial paced), or a spike before the QRS (v-paced)
- CORRECT-ANSWERSsingle
you know a pacemaker is _________ (single/double) chamber paced when
there are sensors in the R atria and R ventricle to be a-paced and v-paced -
CORRECT-ANSWERSdouble
how long should a pt avoid arm/shoulder activity after pacemaker
placement? - CORRECT-ANSWERS4-6 wk
-olol drugs
lower HR and BP - CORRECT-ANSWERSbeta blockers
-iazem drugs
lower HR and BP - CORRECT-ANSWERSCCB
used for PVCs or VT.
lidocaine/amiodarone - CORRECT-ANSWERSantidysrhythmics
what is the most effective antidysrhythmic? - CORRECT-
ANSWERSamiodarone
how is lidocaine administered? - CORRECT-ANSWERSloading dose, then drip
when is lidocaine used? - CORRECT-ANSWERSsymptomatic VT with a pulse
