Introduction
This examination assesses competency in basic and advanced
dysrhythmia interpretation for Relias Dysrhythmia Basic A & B. It
evaluates ECG recognition, cardiac rhythm analysis, and emergency
response for PEA, V-Tach, A-Fib, and heart blocks. Items include
multiple-choice, scenario-based, and rhythm strip questions. The exam
emphasizes real-world decision-making, safe electrical therapy,
pharmacology, and prioritization. Successful performance supports
NCLEX and nursing program readiness in NURS 332 and NUR 211.

fibrillatory baseline.
3. Which rhythm is shown in the ECG strip?

first?
A. Defibrillate
B. Check leads and client
C. Administer epinephrine
D. Start CPR
B. Check leads and client
RATIONALE: Confirm asystole by checking leads, connections,
and the client before treatment.
7. Which finding is characteristic of sinus bradycardia?
A. Rate <60 with normal P-QRS-T
B. Rate >100 with normal P-QRS-T
C. Absent P waves
D. Wide QRS
