Relias Dysrhythmia Basic A Comprehensive Examination 2026/2027 | Verified Questions
,INTRODUCTION
This collection presents thirty-five (35) original, university-level questions developed for the Relias
Dysrhythmia Basic A Comprehensive Competency Examination at Relias Learning. The material is organized
into four core domains: Normal Sinus Rhythm and Basic EKG Principles; Atrial Dysrhythmias and
Conduction Abnormalities; Ventricular Dysrhythmias and Life-Threatening Rhythms; and Heart Blocks and
Pacemaker Rhythms. Every item is written to reinforce the official Relias Dysrhythmia Basic A
Comprehensive Competency Examination course objectives, supporting actual exam readiness and the
development of clinical proficiency in systematic EKG interpretation, rhythm analysis, and evidence-based
cardiac care. Each question is paired with a calibrated rhythm strip recorded at 25 millimeters per second
and 10 millimeters per millivolt. All content is aligned to the 2026/2027 academic year and reflects current
American Heart Association and advanced cardiovascular life support guidance.
ACTUAL QUESTIONS
Domain 1: Normal Sinus Rhythm and Basic EKG Principles
Question 1. A nurse reviews the six second lead II rhythm strip shown below for a stable
client. Which rhythm is displayed?
A. Sinus bradycardia, because the rhythm originates in the sinus node
B. Atrial fibrillation, because the tracing contains small waves before each QRS complex
C. Accelerated junctional rhythm, because the rate is below 100 beats per minute
D. Normal sinus rhythm, because the rate is about 75 beats per minute, the rhythm is regular, one
upright P wave precedes every QRS complex, the PR interval is about 0.16 second, and the QRS duration
is about 0.08 second
Correct Answer: D
Rationale: Normal sinus rhythm requires a rate of 60 to 100 beats per minute, a regular R to R interval,
one P wave of consistent shape before every QRS complex, a PR interval of 0.12 to 0.20 second, and a QRS
duration under 0.12 second. Every one of those five criteria is met on this strip, which is the systematic
approach taught in the Relias Dysrhythmia Basic A course materials.
Question 2. A client reports fatigue and lightheadedness. The lead II rhythm strip shown
below is obtained. Which rhythm is present and what determines the next clinical action?

, A. Normal sinus rhythm, because the rhythm is regular and every QRS complex is narrow
B. Sinus bradycardia with a rate of about 45 beats per minute, and the next action is to assess for signs
of instability such as hypotension, altered mental status, chest pain, or syncope
C. Third degree atrioventricular block, because the rate is slow
D. Atrial fibrillation with a slow ventricular response, because the rhythm is slow and regular
Correct Answer: B
Rationale: Sinus bradycardia is a preserved sinus mechanism with a rate below 60 beats per minute, and
every P wave is still followed by a QRS complex. The rhythm itself is not the trigger for intervention; the
client's stability is. The ACLS bradycardia algorithm directs the clinician to assess for hypotension, altered
mental status, chest pain, or shock and to treat reversible causes before considering atropine or pacing.
Question 3. A client with a temperature of 39.1 C has the lead II rhythm strip shown below.
What is the rhythm and the priority nursing action?
A. Supraventricular tachycardia, because the rate is above 100 beats per minute, so adenosine should be
given immediately
B. Atrial flutter with rapid ventricular response, because the rate is fast
C. Sinus tachycardia at about 118 beats per minute, and the priority is to identify and treat the
underlying cause rather than to slow the rate itself
D. Ventricular tachycardia, because the rate is above 100 beats per minute
Correct Answer: C
Rationale: Per Dubin and standard rhythm interpretation method, sinus tachycardia is a sinus mechanism
with a rate above 100 beats per minute, usually under 150 in adults, with a normal P wave before every
QRS complex. It is a physiologic response to fever, hypovolemia, hypoxia, pain, or anxiety, so care targets
the cause. Supraventricular tachycardia typically presents at 150 to 250 beats per minute with P waves
buried in the preceding T waves.
Question 4. A healthy young adult has the lead II rhythm strip shown below, in which the R to
R interval lengthens and shortens in a repeating pattern. What is the rhythm?
