INTRODUCTION
This assessment evaluates competency in electrocardiography (EKG) as applied in clinical
settings. It measures understanding of cardiac anatomy, electrical conduction, rhythm
interpretation, and appropriate interventions. The exam includes multiple-choice and
scenario-based questions designed to reflect real-world healthcare environments.
Emphasis is placed on accurate rhythm recognition, patient safety, regulatory compliance,
and clinical decision-making. Candidates are expected to apply theoretical knowledge to
practical situations, demonstrating professional judgment consistent with healthcare
standards and patient-centered care.
SECTION 1: QUESTIONS 1–35
1. What is the primary function of the sinoatrial (SA) node?
A. Conduct impulses to ventricles
, 🔴 B. Initiate electrical impulses
C. Delay conduction
D. Contract ventricles
🔵 Explanation: The SA node is the heart’s natural pacemaker and initiates electrical
impulses.
2. Which wave represents atrial depolarization?
A. QRS complex
🔴 B. P wave
C. T wave
D. U wave
🔵 Explanation: The P wave corresponds to atrial depolarization.
3. 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: Normal PR interval is 0.12–0.20 seconds.
, 4. What does the QRS complex represent?
A. Atrial repolarization
🔴 B. Ventricular depolarization
C. Ventricular repolarization
D. SA node firing
🔵 Explanation: QRS reflects ventricular depolarization.
5. Which electrolyte imbalance commonly causes peaked T waves?
A. Hypokalemia
🔴 B. Hyperkalemia
C. Hypocalcemia
D. Hyponatremia
🔵 Explanation: Hyperkalemia causes tall, peaked T waves.
6. What is the normal heart rate range?
A. 40–60 bpm
🔴 B. 60–100 bpm
C. 100–140 bpm
D. 120–160 bpm
🔵 Explanation: Normal adult heart rate is 60–100 bpm.
