1. A patient is scheduled to undergo routine cardiac monitoring in a
clinical setting. The healthcare provider explains that the test will
measure the heart’s electrical impulses using surface electrodes
placed on the chest, arms, and legs, producing a graphical tracing used
for rhythm interpretation. Which credential most directly validates
competency for performing this procedure in most U.S. healthcare
settings?
A. Certified Phlebotomy Technician (CPT)
B. Certified EKG Technician (CET)
C. Certified Nursing Assistant (CNA)
D. Registered Health Information Technician (RHIT)
B. Certified EKG Technician (CET)
The CET credential is specifically designed for individuals trained to
perform electrocardiograms, including electrode placement, rhythm
recognition, and basic cardiac monitoring tasks in clinical
environments.
2. A student enrolled in an EKG technician program is reviewing eligibility
requirements for national certification. Which combination of
requirements is most commonly required across accredited EKG
certification pathways?
A. Bachelor’s degree in nursing and 2 years ICU experience
, B. Completion of approved EKG training and high school diploma or
equivalent
C. Pharmacy technician license and clinical lab experience
D. Medical school completion and cardiology residency
B. Completion of approved EKG training and high school diploma or
equivalent
Most EKG certification programs require a high school diploma or
GED and completion of an approved training program that includes
both theoretical instruction and practical competency development.
3. A candidate preparing for EKG certification is studying cardiac
physiology. Which structure is primarily responsible for initiating
electrical impulses that regulate heart rhythm?
A. Atrioventricular (AV) node
B. Bundle of His
C. Sinoatrial (SA) node
D. Purkinje fibers
C. Sinoatrial (SA) node
The SA node functions as the heart’s natural pacemaker, generating
electrical impulses that establish the baseline rhythm of cardiac
contractions.
4. During EKG electrode placement, a technician notices inconsistent
waveforms due to poor skin contact. What is the most likely cause of
this artifact?
A. Hyperkalemia
B. Muscle necrosis
C. Loose or improperly attached electrodes
D. Myocardial infarction
C. Loose or improperly attached electrodes
Poor electrode contact introduces signal distortion and artifact,
leading to inaccurate waveform interpretation on the EKG tracing.
5. An EKG technician is preparing a patient for a 12-lead ECG. Which
action best ensures accurate test results?
A. Positioning electrodes on clothing for convenience
B. Cleaning and drying skin before electrode placement
C. Asking the patient to hold their breath for the entire test
, D. Increasing machine speed to capture more data
B. Cleaning and drying skin before electrode placement
Proper skin preparation reduces impedance and improves signal
conduction, resulting in clearer and more accurate cardiac tracings.
6. A technician is asked to identify the normal heart rate range for adults
on an EKG. Which range is considered normal sinus rhythm?
A. 30–50 bpm
B. 50–60 bpm
C. 60–100 bpm
D. 100–140 bpm
C. 60–100 bpm
Normal sinus rhythm in adults is typically defined as a heart rate
between 60 and 100 beats per minute under resting conditions.
7. A patient undergoing telemetry monitoring reports dizziness. The EKG
strip shows irregular rhythm with absent consistent P waves. Which
condition is most consistent with this finding?
A. Atrial fibrillation
B. Sinus bradycardia
C. First-degree heart block
D. Ventricular tachycardia
A. Atrial fibrillation
Atrial fibrillation is characterized by irregular rhythm and absence of
distinct P waves due to disorganized atrial electrical activity.
8. Which infection control practice is most important for an EKG
technician working with multiple patients daily?
A. Wearing sterile surgical gloves for all tasks
B. Reusing electrodes after wiping with alcohol
C. Hand hygiene before and after patient contact
D. Avoiding contact with all patient skin surfaces
C. Hand hygiene before and after patient contact
Hand hygiene is the most critical infection control measure to
prevent cross-contamination between patients in clinical settings.
9. A technician is interpreting a basic EKG waveform. Which component
represents ventricular depolarization?
A. P wave
