NUR 2006: ECG: EXAM TEST QUESTIONS WITH
CORRECT ANSWERS
What is cardioversion? -- Answer ✔✔ Low-energy shocks to convert an arrhythmia
back to sinus rhythm
How is defibrillation different than cardioversion? -- Answer ✔✔ Defibrillation is a more
powerful shock whereas cardioversion is less powerful. Defibrillation shocks are
delivered unsynchronized and immediate where as cardioversion shocks are
synchronized with QRS
What is adenosine used for? -- Answer ✔✔ Antiarrhythmic used to treat SVT
Identify the following rhythm:
-- Answer ✔✔ Atrial fibrillation (A-Fib)
,Identify the following rhythm:
-- Answer ✔✔ Atrial fibrillation (A-fib)
What is the heart rate in atrial fibrillation? -- Answer ✔✔ Atria - 350-650, ventricles -
slow to rapid
Atrial fibrillation is an _______ rhythm. -- Answer ✔✔ Irregular
What is an ectopic foci? -- Answer ✔✔ An excitable group of cells that causes an
impulse from a spot other than the SA node
What is the pathophysiology of atrial fibrillation? -- Answer ✔✔ The atria are beating
rapidly and out of sync with the ventricles due to receiving electrical charges from
ectopic foci
What are the causes of atrial fibrillation? -- Answer ✔✔ Age, MI, cardiac surgery, CHF,
digoxin toxicity, HTN, DM
What are the symptoms of atrial fibrillation? -- Answer ✔✔ Thrombus formation, if
ventricular rate is rapid there may be dizziness or shortness of breath, decreased
cardiac output
, What is the treatment for atrial fibrillation? -- Answer ✔✔ Control rate (digoxin,
verapamil, beta blockers), anticoagulation, cardioversion once fully anticoagulated,
catheter ablation
For someone with atrial fibrillation or atrial flutter, they should undergo anticoagulant
therapy until they reach a therapeutic INR of _____. -- Answer ✔✔ 2-3
What is catheter ablation? -- Answer ✔✔ Cauterize the ectopic spots that keep trying
to pace the heart. (May require a pacemaker after this procedure)
What is the left atrial appendage -- Answer ✔✔ Small saclike structure in the left
atrium. In A fib and A flutter, this is a common spot where blood can pool and
thrombus can form.
What is a Watchman procedure? -- Answer ✔✔ A type of implant that blocks off the
left atrial appendage and decreases the risk of traveling blood clots.
What is the heart rate typically in atrial flutter? -- Answer ✔✔ Atria - 220-430,
Ventricles <300
Identify the following rhythm:
