Echelon Pt 2 Rhythms Exam Questions With Complete
Solutions
2nd degree block type II Correct Answer ECG strip that
shows regular atrial rhythm, an atrial rate greater than
ventricular rate (some QRS complexes are dropped) and a
constant PR interval when the atrial and ventricular complexes
appear together would most likely be identified as what rhythm?
A. 2nd degree heart block type II Correct Answer The P wave
is never hidden in which one of the following rhythms?
A. 2nd degree heart block type II
B. 3rd degree heart block
C. Junctional
D. Supraventricular tachycardia (SVT)
A. PR intervals Correct Answer Which is a key to
differentiating 2nd degree block type I from type II?
A. PR intervals
B. P waves
C. Rate
D. Rhythm
Correct
B. 2nd degree heart block type II Correct Answer What
rhythm is characterized by a conduction block between the atria
and ventricles resulting in some nonconducted P waves (QRS
complex drops) but fixed PR intervals when the P wave and
QRS complex appear together?
A. Bundle branch block (BBB)
B. 2nd degree heart block type II
, C. 3rd degree heart block at bundle branch block level
D. Idioventricular rhythm (IVR)
B. 30 seconds Correct Answer What period of time defines a
sustained ventricular tachycardia?
A. 2 seconds
B. 30 seconds
C. 120 seconds
D. 300 minutes
B. Access the patient; initiate CPR; defibrillate ASAP Correct
Answer Which is the correct intervention sequence for
ventricular fibrillation?
A. Access the patient; initiate CPR; administer epinephrine

CPR Correct Answer Which is the correct intervention
sequence for asystole?
