• Adequate electrode gel purpose . Answer: To prevent wandering baseline, ensure
proper adhesion of electrodes, facilitate electrical conductivity, and reduce patient
discomfort.
• Stable blood pressure indication . Answer: Normal heart activity.
• Essential tools for remote cardiac device monitoring . Answer: Batteries, electrodes,
rubber band, adhesive tape.
• First-degree AV block indication . Answer: Prolonged PR interval.
• Heart rhythm with prolonged PR interval until QRS dropped . Answer: Second-degree
AV block, Mobitz type I.
• Most common output for a 12-lead ECG . Answer: Printed format.
• P wave analysis feature . Answer: Size and shape.
• Atrial rate from peak to peak flutter waves . Answer: 120 bpm.
• Causes of ectopic beats in ECG . Answer: Dehydration, excessive artifact, electrolyte
imbalances, age-related decline.
• Action during routine pacemaker check with shortness of breath . Answer: Put the
patient on hold and call the pacemaker nurse.
• Valves preventing backflow during diastole . Answer: Semilunar.
• Information not used for patient identification . Answer: Room number.
• Isoelectric line of ECG tracing indication . Answer: No electrical activity.
• Correct practice in patient care documentation . Answer: The ECG was performed;
however, the patient was belligerent.
• Chain of infection proper sequence . Answer: Source, means of transmission,
susceptible host.
,• Sinus arrest . Answer: Considered when it continues for 5 seconds or more.
• First degree heart block . Answer: PR interval is constant and greater than 0.20
seconds in duration.
• ECG interpretations . Answer: Usually the responsibility of a physician.
• Telemetry monitor operator . Answer: Typically operated by a nurse.
• Ventricular dysrhythmia depolarization . 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 . Answer: Another name is Wenckebach.
• Ventricular fibrillation . Answer: Typically described as chaotic.
• Patient safety process . Answer: Critical for ensuring patient safety in a clinical setting.
• Structure transporting blood to lungs . Answer: Pulmonary artery.
• Legality and ethics relationship . Answer: Illegal acts are not always unethical.
• Rhythm characterized by regularity and five complete cycles . Answer: Sinus rhythm.
• Dysrhythmia with irregularity and no distinguishable P waves . Answer: Atrial
fibrillation.
• Stimulation of electrical current from pacemaker generator . Answer: Triggered.
• Dual chamber pacemaker's ventricular lead sensing non-cardiac signal . Answer: Most
likely to result in failure to capture ventricle.
• Assessing regularity of an ECG . Answer: Involves measuring distances between R-R
intervals.
• ECG characteristic indicative of myocardial ischemia . Answer: Changes in the ST
segment and T waves.
• Monitor for ECG tracings from remote areas . Answer: Telemetry monitor.
• Standard precautions in healthcare safety practices . Answer: Combining universal
precautions and isolation methods.
• Importance of complete patient history before ECG . Answer: To prepare for potential
complications.
, • Normal sinus rhythm range . Answer: Typically ranges from 60-100 bpm.
• Sinus bradycardia . Answer: Heart rate less than 60 bpm.
• Sinus dysrhythmia . Answer: Characterized by a variation in heart rate with breathing.
• Code Blue Medical Emergency . Answer: A situation requiring immediate medical
attention.
• Atrial flutter . Answer: Dysrhythmia characterized by a rapid, regular atrial rate.
• Ventricular flutter . Answer: Dysrhythmia characterized by a rapid, regular ventricular
rate.
• Holter monitor . Answer: A portable device for continuously monitoring heart rhythms.
• Normal sinus rhythm . Answer: Typically ranges from 60-100 bpm.
• Cause to discontinue exercise electrocardiography . Answer: Patient is complaining of
shortness of breath.
• Conduction system part that conducts impulses down both sides of the interventricular
septum . Answer: Bundle branches.
• Lead wires used to record a 12-lead ECG . Answer: 12
• Best next step when a patient experiences an event while monitored . Answer: Contact
the patient/spouse and review the information listed and try to get more details.
• Inventor of the first ECG machine . Answer: Wilhelm Einthoven.
• Purpose of the ICD-9 code . Answer: Diagnostic codes used to ensure that proper
treatment is provided for the patient.
• Study of electrical activity of the heart . Answer: Electrocardiology.
• Primary responsibility of a technician during a patient ECG . Answer: Ensuring
accurate electrode placement.
• Primary purpose of using an electrocardiogram (ECG) . Answer: To assess the heart's
electrical activity.
• Next step if a patient experiences shortness of breath during a transtelephonic
pacemaker check . Answer: Put the patient on hold and call the pacemaker nurse.
