NHA EKG CERTIFICATION TEST 2026/2027 – Complete Questions and Correct Answers | Verified Study Guide for Certified EKG Technician (CET)

Pass your NHA Certified EKG Technician (CET) exam with confidence using this comprehensive 2026/2027 updated study guide! This complete test bank features verified questions and correct answers covering every essential topic for EKG certification, from lead placement and waveform interpretation to patient preparation and emergency protocols. Master every key concept tested on the NHA EKG Certification Exam: Lead Placement & Electrodes: 12-lead EKG placement, right-sided EKG (V4R for RV ischemia), posterior leads (V7-V9), modified placements for amputations, 5-lead holter placement, and Einthoven's Triangle Waveform Interpretation: P wave (atrial depolarization, enlargement), PR interval (AV node conduction), QRS complex (septal wall V1/V2, ventricular depolarization), ST segment (elevation/depression), T wave inversion, U wave significance Rhythm Recognition: Sinus rhythm, atrial fibrillation, ventricular fibrillation, accelerated idioventricular rhythm, third-degree AV block, and 6-second method for rate calculation Artifact Recognition & Troubleshooting: Wandering baseline (loose electrodes, wire tension), electrical interference (frayed wires), calibration issues, gain control (5mm/mv), paper speed (50mm/sec) Myocardial Infarction Patterns: Lateral infarction (leads I, aVL, V5-V6), inferior wall MI, ischemia (ST depression, T inversion), injury (ST elevation) Stress Testing: Exercise stress test protocols, contraindications (CHF), stopping criteria (dizziness, hyperventilation), patient preparation (smoking restrictions), monitoring vital signs Holter Monitoring: Application steps, patient diary (running, symptoms), artifact prevention, shower restrictions, duration of monitoring Patient Care & Communication: Patient education, implied consent, confidentiality (HIPAA violations), responding to patient concerns, documenting procedures Vital Signs & Assessment: Heart rate ranges (adult 60-100, child 80-120, newborn 30-49), pulse sites (radial, brachial), respiratory rate counting techniques Emergency Response: Ventricular fibrillation (call for help, begin CPR), unresponsive patient protocols, notifying providers of critical findings Anatomy & Physiology: Coronary artery supply, cardiac conduction system, AV node function, septal wall identification Professional & Legal Issues: Patient confidentiality (PHI sharing), scope of practice, quality assurance inquiries, documentation requirements Perfect for EKG technicians, monitor technicians, telemetry staff, and healthcare professionals preparing for NHA, NCCT, or other EKG certification exams. This guide breaks down complex concepts like how to identify specific infarction locations by lead involvement, when to change paper speed, and how to properly place electrodes for modified EKGs.
