Certified Rhythm Analysis Technician (CRAT)
Practice Exam Review UPDATED
QUESTIONS AND CORRECT ANSWERS
ECG tracing legal information - CORRECT ANSWER Patient's social security
number, physician's name, and location; patient's date of birth, diagnosis, and medication
being taken; physician's name, your name, and patient's address; patient's name, date, and
time of day.
Adequate electrode gel purpose - CORRECT ANSWER To prevent wandering
baseline, ensure proper adhesion of electrodes, facilitate electrical conductivity, and reduce
patient discomfort.
Stable blood pressure indication - CORRECT ANSWER Normal heart activity.
Essential tools for remote cardiac device monitoring - CORRECT ANSWER Batteries,
electrodes, rubber band, adhesive tape.
First-degree AV block indication - CORRECT ANSWER Prolonged PR interval.
Heart rhythm with prolonged PR interval until QRS dropped - CORRECT
ANSWER Second-degree AV block, Mobitz type I.
Most common output for a 12-lead ECG - CORRECT ANSWER Printed format.
P wave analysis feature - CORRECT ANSWER Size and shape.
Atrial rate from peak to peak flutter waves - CORRECT ANSWER 120 bpm.
Causes of ectopic beats in ECG - CORRECT ANSWER Dehydration, excessive
artifact, electrolyte imbalances, age-related decline.
,Action during routine pacemaker check with shortness of breath - CORRECT
ANSWER Put the patient on hold and call the pacemaker nurse.
Valves preventing backflow during diastole - CORRECT ANSWER Semilunar.
Information not used for patient identification - CORRECT ANSWER Room number.
Isoelectric line of ECG tracing indication - CORRECT ANSWER No electrical
activity.
Correct practice in patient care documentation - CORRECT ANSWER The ECG was
performed; however, the patient was belligerent.
Chain of infection proper sequence - CORRECT ANSWER Source, means of
transmission, susceptible host.
Sinus arrest - CORRECT ANSWER Considered when it continues for 5 seconds or
more.
First degree heart block - CORRECT ANSWER PR interval is constant and greater
than 0.20 seconds in duration.
ECG interpretations - CORRECT ANSWER Usually the responsibility of a physician.
Telemetry monitor operator - CORRECT ANSWER Typically operated by a nurse.
Ventricular dysrhythmia depolarization - CORRECT ANSWER Takes longer than
normal because the current is initiated within the Purkinje fibers, and the electrical
stimulation occurs from the ventricular cell-to-cell conduction.
,Second degree AV block type I - CORRECT ANSWER Another name is Wenckebach.
Ventricular fibrillation - CORRECT ANSWER Typically described as chaotic.
Patient safety process - CORRECT ANSWER Critical for ensuring patient safety in a
clinical setting.
Structure transporting blood to lungs - CORRECT ANSWER Pulmonary artery.
Legality and ethics relationship - CORRECT ANSWER Illegal acts are not always
unethical.
Rhythm characterized by regularity and five complete cycles - CORRECT
ANSWER Sinus rhythm.
Dysrhythmia with irregularity and no distinguishable P waves - CORRECT
ANSWER Atrial fibrillation.
Stimulation of electrical current from pacemaker generator - CORRECT
ANSWER Triggered.
Dual chamber pacemaker's ventricular lead sensing non-cardiac signal - CORRECT
ANSWER Most likely to result in failure to capture ventricle.
Assessing regularity of an ECG - CORRECT ANSWER Involves measuring distances
between R-R intervals.
ECG characteristic indicative of myocardial ischemia - CORRECT ANSWER Changes
in the ST segment and T waves.
, Monitor for ECG tracings from remote areas - CORRECT ANSWER Telemetry
monitor.
Standard precautions in healthcare safety practices - CORRECT ANSWER Combining
universal precautions and isolation methods.
Importance of complete patient history before ECG - CORRECT ANSWER To prepare
for potential complications.
Normal sinus rhythm range - CORRECT ANSWER Typically ranges from 60-100
bpm.
Sinus bradycardia - CORRECT ANSWER Heart rate less than 60 bpm.
Sinus dysrhythmia - CORRECT ANSWER Characterized by a variation in heart rate
with breathing.
Code Blue Medical Emergency - CORRECT ANSWER A situation requiring
immediate medical attention.
Atrial flutter - CORRECT ANSWER Dysrhythmia characterized by a rapid, regular
atrial rate.
Ventricular flutter - CORRECT ANSWER Dysrhythmia characterized by a rapid,
regular ventricular rate.
Holter monitor - CORRECT ANSWER A portable device for continuously monitoring
heart rhythms.
Normal sinus rhythm - CORRECT ANSWER Typically ranges from 60-100 bpm.
