Relias Dysrhythmia Basic Test Answer Key Guide | High-Score Study Material Relias Dysrhythmia Basic A - answer - Exam Coverage Exam coverage for Relias Dysrhythmia Basic A includes introductory ECG interpretation and cardiac rhythm monitoring concepts. It focuses on the electrical conduction system of the heart, ECG waveform components, rhythm strip analysis, heart rate calculation, and identification of normal sinus rhythm, sinus arrhythmias, atrial rhythms, junctional rhythms, ventricular rhythms, and atrioventricular blocks. The exam also evaluates understanding of the clinical implications of rhythm disturbances and appropriate initial nursing or clinical responses. Emphasis is placed on recognizing basic dysrhythmias accurately, correlating monitor findings with patient status, and supporting safe, timely intervention in clinical settings. Sinus Bradycardia - answer - Regular Rate: 60 P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: 0.12 sec Normal sinus rhythm - answer - Regular Rate: 60-100 P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: 0.12 sec Sinus Tachycardia - answer - Regular Rate: 100-150 P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: 0.12 sec Premature Atrial Contraction - answer - IRREGULAR Rate: depends on underlying rhythm P wave: Present or hidden in T wave PR Interval: 0.12-0.20 sec QRS: 0.12 sec Atrial Fibrillation - answer - IRREGULAR Atrial rate: UNMEASURABLE Ventricular rate: variable P wave: unable to see PR Interval: N/A QRS: 0.12 sec A fib RVR - answer - IRREGULAR Ventricular rate: 100-175 P wave: unable to see PR Interval: N/A QRS 0.12 sec Atrial Flutter - answer - Usually REGULAR can be irregular Atrial rate: 250-350 Ventricular rate: variable BUT atrial rate P Wave: Flutter PR Interval: N/A QRS: 0.12 sec Supraventricular Tachycardia - answer - Regular Rate: 150-350 P wave: Hidden in QRS or T wave PR: unable to determine QRS: 0.12 sec Junctional Rhythm - answer - Regular Rate: 40-60 P Wave: ABSENT or INVERTED PR Interval: None or 0.12 QRS: 0.12 sec Accelerated Junctional Rhythm - answer - Regular Rate: 60-100 P Wave: NONE or INVERTED PR Interval: None or 0.12 QRS: 0.12 sec Junctional Tachycardia - answer - Regular Rate: 100 P Wave: NONE or INVERTED PR Interval: None or 0.12 QRS: 0.12 sec Premature Ventricular Contraction - answer - IRREGULAR Rate: refer to underlying rhythm P Wave: NONE PR Interval: N/A QRS: WIDE and BIZARRE , 0.12 sec Ventricular Tachycardia - answer - Regular Rate: 100 P Wave: NONE PR Interval: N/A QRS: WIDE and BIZARRE, 0.12 sec Ventricular Fibrillation - answer - Chaotic Coarse: big waves Fine: small waves Rate: unmeasurable P Wave: NONE PR Interval: N/A QRS: N/A Idioventricular - answer - Regular Rate: 20-50 P wave: NONE PR Interval: N/A QRS: WIDE, 0.12 sec Accelerated Idoventricular Rhythm - answer - Regular Rate: 50-100 P wave: NONE PR Interval: N/A QRS: WIDE, 0.12 sec 1st Degree AV Block - answer - Regular Rate: 60-100 P Wave: Present, upright PR interval: 0.20 sec CONSISTENTLY LONG QRS: 0.12 sec Husband stays late till 9 consistently 2nd Degree AV Block Type I Mobitz, Wenckebach - answer - IRREGULAR Rate: 60-100 P wave: Present, upright PR Interval: Progressively longer until drop (PR interval longer and longer until drop) QRS: 0.12 sec Husband stays late till 9, then 11, then 1, then doesn't come home at all 2nd Degree AV Block Type II - answer - Irregular or regular Rate: 60 P wave: Present, upright PR Interval: PR interval consistently LONGER like type 1 but then a QRS will drop QRS: 0.12 sec Husband stays late till 9 consistently, then wife goes out and doesn't come home 3rd Degree AV Block - answer - Atrials and ventricles don't communicate Rate: regular atrial P wave: Present, upright No relationship between P waves and QRS PR Interval:
