Relias Dysrhythmia Basic A | Expert Strategies, Review of (55) Key Practice Questions and Verified Detailed Answers; for Guaranteed Success

This Relias Dysrhythmia Basic A exam is a 55-question competency assessment used by healthcare organizations to evaluate a nurse's or telemetry technician’s capability to read and manage cardiac rhythms. Exam Overview The test evaluates foundational electrocardiogram (ECG) interpretation metrics across five key rhythm categories, pacemaker functionality, and immediate clinical emergency protocols. • Format: 55 Multiple-choice questions. & Diagrams • Core Task: • Target Passing Score ________________________________________ Core Measurement Criteria • PR Interval: Normal is 0.12 to 0.20 seconds (3–5 small boxes). • QRS Complex: Normal is less than 0.12 seconds • QT Interval: 0.43 seconds. • ECG Grid Value: ________________________________________ Critical Rhythms Covered on the Exam 1. Sinus Node Rhythms • Normal Sinus Rhythm (NSR): • Sinus Bradycardia: • Sinus Tachycardia: Regular; rate 100–150 bpm. 2. Atrial Rhythms • Atrial Fibrillation (A-Fib): Irregularly irregular • A-Fib with Rapid Ventricular Response (RVR): 100–175 bpm. • Atrial Flutter: saw-toothed baseline flutter (F) waves; • Supraventricular Tachycardia (SVT): 150–350 bpm; 3. Junctional Rhythms • Inherent Junctional: absent, inverted, or retrograde P waves. • Accelerated Junctional: 4. Ventricular & Lethal Rhythms • Ventricular Tachycardia (V-Tach):; wide, bizarre QRS complexes (0.12s); • Ventricular Fibrillation (V-Fib): • Idioventricular Rhythm: • Pulseless Electrical Activity (PEA): 5. Atrioventricular (AV) Heart Blocks • First-Degree AV Block: consistently prolonged PR interval (0.20 seconds); • Second-Degree Type I (Wenckebach): • Second-Degree Type II (Mobitz II): • Third-Degree (Complete) Heart Block: 6. Pacemaker Functionality • Atrial vs. Ventricular Pacing: • Failure to Capture: corresponding P wave or QRS complex. • Failure to Sense ________________________________________ Emergency Interventions Teste • For V-Fib and Pulseless V-Tach: defibrillation; • For Symptomatic Bradycardia: • For Stable SVT: Adenosine
