How many questions are on the NHA Certified EKG Technician (CET) exam, and how many are scored?
The exam has 100 scored questions.
What scaled score is required to pass the CET exam?
A scaled score of 390 or higher.
Roughly how much time can you spend per question if you pace evenly on the CET exam?
About 1.2 minutes per question, since 120 minutes are split across 100 questions.
Which limb-lead electrode is the ground/reference and is never part of the recorded bipolar leads?
The right leg (RL) electrode serves as the ground/reference.
On a 12-lead EKG, what wave represents ventricular repolarization?
The T wave (atrial repolarization is hidden within the QRS complex).
What is the defining feature of ventricular fibrillation (V-fib) on an EKG, and why is it a medical emergency?
Chaotic, disorganized waveforms with no identifiable P, QRS, or T waves; the ventricles quiver instead of pumping, so it requires immediate defibrillation.
What is artifact on an EKG, and name a common cause.
Artifact is unwanted electrical interference distorting the tracing; common causes include patient movement, muscle tremor, loose electrodes, and 60-cycle (AC) interference.
