INTRODUCTION
This assessment is designed to evaluate competency in recognizing and managing cardiac
dysrhythmias in clinical settings. It covers foundational electrophysiology, ECG
interpretation, and identification of common arrhythmias. The exam incorporates multiple-
choice and scenario-based questions to assess clinical judgment, patient safety awareness,
and appropriate intervention strategies. Emphasis is placed on real-world application,
including monitoring, escalation of care, and adherence to professional standards. This
testbank supports learners in developing critical thinking skills necessary for safe and
effective cardiac rhythm interpretation in healthcare environments.
,SECTION 1: QUESTIONS 1–35
1. What is the primary pacemaker of the heart?
A. Atrioventricular (AV) node
🔴 B. Sinoatrial (SA) node
C. Bundle of His
D. Purkinje fibers
🔵 Explanation: The SA node initiates electrical impulses and sets the heart rate under
normal conditions.
2. What is the normal resting heart rate range for adults?
A. 40–60 bpm
🔴 B. 60–100 bpm
C. 100–120 bpm
D. 120–160 bpm
🔵 Explanation: A normal adult resting heart rate falls between 60 and 100 beats per
minute.
, 3. Which ECG component represents atrial depolarization?
A. QRS complex
🔴 B. P wave
C. T wave
D. PR interval
🔵 Explanation: The P wave reflects atrial depolarization.
4. A prolonged PR interval indicates:
A. Ventricular hypertrophy
🔴 B. Delayed AV conduction
C. Rapid atrial firing
D. Myocardial ischemia
🔵 Explanation: A prolonged PR interval (>0.20 sec) suggests slowed conduction
through the AV node.
5. What rhythm is characterized by an irregularly irregular pattern?
A. Sinus tachycardia
🔴 B. Atrial fibrillation
C. Ventricular tachycardia
