RELIAS DYSRHYTHMIA BASIC B TEST EXAM WITH
ACTUAL 2026-27 QUESTIONS AND ANSWERS
Overview
The Relias Dysrhythmia Basic B Test evaluates a learner’s ability to identify,
interpret, and clinically respond to common cardiac dysrhythmias using ECG
rhythm strips. The exam focuses on foundational cardiac electrophysiology,
systematic rhythm analysis, recognition of atrial, junctional, and ventricular
rhythms, heart blocks, pacemaker rhythms, and basic clinical interventions.
Emphasis is placed on rate, rhythm regularity, P waves, PR interval, QRS
duration, and appropriate nursing actions based on patient stability.
Relias Dysrhythmia Basic B Test – Full Exam
Format: Multiple Choice
Difficulty: Basic–Intermediate
Total Questions: 100

1. What is the normal PR interval range?
A. 0.06–0.10 sec
B. 0.12–0.20 sec
C. 0.22–0.30 sec
D. 0.30–0.40 sec
Correct Answer: B
Rationale: A normal PR interval reflects proper AV conduction
and ranges from 0.12 to 0.20 seconds.
2. Which rhythm has a rate of 60–100 bpm, regular rhythm,
and upright P waves?
A. Sinus bradycardia
B. Sinus tachycardia
C. Normal sinus rhythm
D. Atrial flutter
Correct Answer: C
Rationale: Normal sinus rhythm meets all normal ECG criteria
including rate, rhythm, and P wave morphology.

3. A heart rate below 60 bpm with normal P waves indicates:
A. Junctional rhythm
B. Sinus bradycardia
C. Ventricular escape rhythm
D. Atrial fibrillation
Correct Answer: B
Rationale: Sinus bradycardia originates from the SA node with a
slow rate but normal conduction.
4. Which rhythm is characterized by absent P waves and an
irregularly irregular rhythm?
A. Atrial flutter
B. Atrial fibrillation
C. Ventricular tachycardia
D. Junctional rhythm
Correct Answer: B
Rationale: Atrial fibrillation shows chaotic atrial activity, no
identifiable P waves, and irregular R-R intervals.
5. A sawtooth pattern on ECG is characteristic of:
A. Atrial fibrillation
B. Ventricular flutter
, 4
C. Atrial flutter
D. Sinus tachycardia
Correct Answer: C
Rationale: Atrial flutter produces classic flutter (F) waves
resembling a sawtooth pattern.
6. A PR interval that progressively lengthens until a beat is
dropped indicates:
A. First-degree AV block
B. Second-degree AV block Type I
C. Second-degree AV block Type II
D. Third-degree AV block
Correct Answer: B
Rationale: Mobitz I (Wenckebach) shows gradual PR
prolongation followed by a dropped QRS.
7. Which AV block has constant PR intervals with intermittent
dropped QRS complexes?
A. First-degree
B. Second-degree Type I
C. Second-degree Type II
D. Third-degree
