– compRehensive competency examination | | veRiFieD
By expeRts .
INTRODUCTION
This comprehensive examination contains 35 verified questions designed to reinforce the core
competencies of the Relias Dysrhythmia Basic A certification for the 2026/2027 academic
year. The exam tests the ability to recognize and interpret basic cardiac rhythms, identify key
features of ECG waveforms, and understand the clinical implications of dysrhythmias. This
assessment is widely used by healthcare organizations to evaluate competency in rhythm
interpretation among nurses and telemetry technicians.
The questions address four core domains: ECG Foundations and Measurements (ECG
paper, intervals, cardiac anatomy, conduction system), Sinus and Atrial Rhythms (Normal
Sinus Rhythm, Sinus Bradycardia, Sinus Tachycardia, Atrial Fibrillation, Atrial
Flutter), Junctional and Ventricular Rhythms (Junctional Rhythms, Premature Ventricular
Complexes, Ventricular Tachycardia, Ventricular Fibrillation), and Heart Blocks and Lethal
Arrhythmias (AV Blocks, Asystole, PEA, Clinical Interventions). Each item requires application
of foundational dysrhythmia knowledge drawn from established Relias curriculum materials,
ACLS guidelines, and evidence-based practice standards. Successful completion supports
development of the clinical judgment required for safe and effective cardiac monitoring and
patient care.
DOMAIN 1: ECG FOUNDATIONS AND MEASUREMENTS
(Questions 1-10)
Question 1. The electrical impulse normally originates from which structure of the heart?
A. AV node
B. Bundle of His
C. SA node
D. Purkinje fibers
coRRect answeR: C
Rationale: The sinoatrial (SA) node, located in the upper wall of the right atrium, is the heart's
natural pacemaker. It normally discharges at 60-100 beats per minute. The AV node delays
impulses before passing them to the ventricles; the Bundle of His and Purkinje fibers are part of
the conduction pathway but do not initiate the impulse.
Question 2. At what rate does the SA node normally fire in a resting adult?
