,Introduction
This practice exam is designed to prepare candidates for the Illinois EKG Technician certification examination
by assessing essential knowledge and skills required for competent professional practice. The test evaluates
fundamental understanding of cardiac anatomy, EKG acquisition procedures, waveform analysis, and
arrhythmia identification. Questions are structured as multiple-choice and scenario-based items that
emphasize real-world application, critical decision-making, and professional judgment in clinical settings.
Candidates will demonstrate proficiency in patient care safety, regulatory compliance, equipment handling,
and appropriate responses to cardiac emergencies. This assessment mirrors the format and difficulty of the
actual certification exam to ensure comprehensive preparation.
Section One: Questions 1–100
Question 1
What is the primary function of the SA node in cardiac conduction?
A. To transmit electrical impulses to the ventricles
B. To act as the heart's primary pacemaker
C. To delay impulses before ventricular contraction
D. To contract the atrial muscles directly
🟢 B. To act as the heart's primary pacemaker
🔴 RATIONALE: The sinoatrial (SA) node generates electrical impulses at 60-100 beats per minute, making it
the heart's natural pacemaker that initiates each cardiac cycle.
,Question 2
A patient is scheduled for a stress test. What instruction should the EKG technician provide?
A. Eat a heavy meal before the test for energy
B. Wear loose clothing and comfortable shoes
C. Take all regular medications without adjustment
D. Avoid drinking water for 24 hours before testing
🟢 B. Wear loose clothing and comfortable shoes
🔴 RATIONALE: Proper attire facilitates electrode placement and allows safe movement during stress testing;
heavy meals and unadjusted medications may interfere with test results.
Question 3
Which regulation requires EKG technicians to protect patient privacy?
A. OSHA
B. HIPAA
C. CDC
D. FDA
🟢 B. HIPAA
🔴 RATIONALE: The Health Insurance Portability and Accountability Act (HIPAA) mandates protection of
patient health information and privacy, a core ethical standard for EKG technicians.
, Question 4
What is the correct sequence for preparing skin before electrode placement?
A. Clean, shave, abrade
B. Shave, clean, abrade
C. Ablate, shave, clean
D. Clean, abrade, shave
🟢 B. Shave, clean, abrade
🔴 RATIONALE: Hair must be removed first (shave), then skin cleaned to remove oils, followed by gentle
abrasion to reduce impedance for optimal signal quality.
Question 5
Which artifact appears as a wandering baseline on an EKG tracing?
A. Patient trembling
B. Poor electrode contact
C. External electrical interference
D. Loose lead wire
🟢 B. Poor electrode contact
🔴 RATIONALE: A wandering baseline typically indicates inadequate electrode-skin contact or improper
electrode application, causing the baseline to drift up and down.
