Exam 2: Dysrhythmias Flashcards
what are the nursing actions when placing a 12lead ECG
- client is supine with chest exposed
- wash skin
- clip (do not shave) the hair
the 8 steps in analyzing the strip
- determine HR
- rhythm
- analyze P wave
- measure PR
- measure QRS
- examine ST segment (depression or elevation)
- assess T wave
- measure QT
what dysrhythmias are indicated for cardioversion
- supraventricular tachycardia
- ventricular tachycardia (w/ pulse)
- atrial dysrhythmias
defibrillation is used for
ventricular fibrillation or pulseless ventricular tachycardia
what medication will be given to a patient who has sinus bradycardia who is symptomatic
atropine; dopamine, or epinephrine IV (atropine 1st)
what medications are used when a client has:
- atrial fibrillation
- supraventricular tachycardia
- ventricular tachycardia W/pulse
amiodarone, adenosine, verapamil
if a patient has ventricular tachycardia without a pulse the nurse will give
amiodarone, lidocaine, epinephrine
and defibrillation
the nurse should recognize what clients are at risk for development of dysrhythmias
- metabolic alkalosis
- a client who has COPD
- a client who underwent stent placement
a client who is scheduled to undergo cardioversion should
- take anticoagulant 4-6 weeks before the procedure
what should the nurse document after a client experienced defibrillation
- follow up ECG
- energy settings used
- skin condition under electrodes
the nurse monitoring the ECG of a patient with hyperthyroidism observes regular, sawtooth shaped flutter waves with atrial rate of 250bpm
Atrial flutter - atrial flutter is a tachydyrhythmia identified by flutter (fwaves) sawtoothed pattern 200-350bpm
if the HR is less than 60 with regular rhythm and normal P waves is
sinus bradycardia
for which dysrhythmia is defibrillation primarily indicated
Ventricular fibrillation
______ are the treatment of choice for 3rd degree heart block.
pacemakers
ST elevation is a manifestation of
myocardial infarction
