Introduction
This assessment evaluates competency in ECG interpretation, cardiology principles, and
nursing responsibilities in cardiac care settings. It measures foundational knowledge,
rhythm recognition, and clinical decision-making skills essential for safe patient
management. Questions are structured in a multiple-choice format, incorporating both
theoretical understanding and real-world clinical scenarios. Emphasis is placed on accurate
rhythm identification, appropriate intervention selection, and adherence to professional
and ethical standards. The exam is designed to simulate certification-level expectations,
ensuring readiness for practical application in acute and critical care environments.
,Section 1: Questions 1–35
1. What does the P wave represent on an ECG?
A. Ventricular depolarization
🔴 B. Atrial depolarization
C. Ventricular repolarization
D. AV node delay
🔵 Explanation: The P wave reflects atrial depolarization as electrical impulses spread
across the atria.
2. A normal PR interval duration is:
A. 0.04–0.10 seconds
🔴 B. 0.12–0.20 seconds
C. 0.22–0.30 seconds
D. 0.30–0.40 seconds
🔵 Explanation: The normal PR interval ranges from 0.12 to 0.20 seconds, indicating
proper conduction from atria to ventricles.
, 3. Which structure is the primary pacemaker of the heart?
🔴 A. Sinoatrial (SA) node
B. Atrioventricular (AV) node
C. Bundle of His
D. Purkinje fibers
🔵 Explanation: The SA node initiates impulses at a normal rate of 60–100 bpm.
4. What is the normal heart rate range for adults?
A. 40–60 bpm
🔴 B. 60–100 bpm
C. 100–120 bpm
D. 120–160 bpm
🔵 Explanation: A normal resting adult heart rate is 60–100 beats per minute.
5. Which ECG component represents ventricular depolarization?
A. P wave
B. PR interval
🔴 C. QRS complex
