The local metadata lists a scaled score of 390 on a 200 to 500 scale as the passing standard.

Q: What is the largest NHA CET domain?

EKG Acquisition is the largest listed domain at 44%, so lead placement, equipment workflow, and artifact control should get heavy practice time.

Q: Do these flashcards teach diagnosis?

No. The cards focus on entry-level EKG technician tasks: preparation, acquisition quality, safety, documentation, and recognizing when findings need escalation.

Q: How should I use NHA CET flashcards?

Recall the card, then say the next safe technician action out loud. This converts definitions into the workflow thinking tested on CET scenarios.

Question 1

NHA CET Exam Structure

Accepted Answer

The CET exam has 120 total items: 100 scored questions and 20 unscored pretest items. Pretest items are mixed in, so answer every item seriously.

Question 2

NHA CET Time Limit

Accepted Answer

Candidates have 2 hours for the exam. Timed practice should build steady pacing without rushing patient-safety or lead-placement scenarios.

Question 3

NHA CET Passing Score

Accepted Answer

The passing standard in the local metadata is a scaled score of 390 on a 200 to 500 scale. A scaled score is not a raw percentage.

Question 4

CET Blueprint Domains

Accepted Answer

The local test plan groups CET content into Safety and Compliance, EKG Acquisition, and EKG Analysis and Interpretation. Acquisition is the largest domain.

Question 5

CET Eligibility Mindset

Accepted Answer

Before scheduling, confirm the current NHA eligibility pathway, application status, testing rules, and documentation. Administrative readiness is part of exam readiness.

Question 6

CET Retake Rule

Accepted Answer

The local metadata states a 30-day wait after a failed attempt and a one-year wait after the third failed attempt. Always confirm current NHA policy before retesting.

Question 7

Two Patient Identifiers

Accepted Answer

Use two approved identifiers before any EKG procedure. Name and date of birth are stronger than room number, bed location, or visual recognition.

Question 8

EKG Technician Scope

Accepted Answer

A CET acquires quality tracings and reports concerning findings through the correct channel. Diagnosis and treatment decisions belong to licensed providers.

Question 9

Patient Privacy

Accepted Answer

Protect EKG records as health information. Share results only through authorized workflows and avoid discussing patient details in public areas.

Question 10

Standard Precautions

Accepted Answer

Use hand hygiene, PPE when exposure is possible, safe equipment handling, and proper cleaning between patients. Treat each patient encounter as a safety workflow.

Question 11

Emergency Response

Accepted Answer

If the patient becomes unstable, follow facility emergency protocol, call for help, and prioritize patient safety. Do not keep troubleshooting the tracing while the patient deteriorates.

Question 12

Equipment Safety Check

Accepted Answer

Inspect cords, electrodes, power status, paper, and machine readiness before acquisition. Faulty equipment can create artifact or delay care.

Question 13

Explain the Procedure

Accepted Answer

Use clear, calm instructions before placing leads. Explaining what will happen reduces motion artifact, improves cooperation, and supports patient dignity.

Question 14

Skin Preparation

Accepted Answer

Clean, dry skin and remove barriers such as lotion, sweat, or hair when needed. Good skin contact reduces artifact and improves signal quality.

Question 15

Patient Positioning

Accepted Answer

A standard 12-lead EKG is usually acquired with the patient still, relaxed, and positioned consistently. Document nonstandard positioning when policy requires it.

Question 16

Limb Lead Placement

Accepted Answer

Place limb electrodes consistently according to facility protocol and avoid switching right and left sides. Lead reversal can mimic or hide important findings.

Question 17

V1 Placement

Accepted Answer

V1 is placed at the fourth intercostal space at the right sternal border. Accurate chest landmarking matters because small placement errors can alter waveform appearance.

Question 18

V2 Placement

Accepted Answer

V2 is placed at the fourth intercostal space at the left sternal border. V1 and V2 establish the starting landmarks for the remaining precordial leads.

Question 19

V4 Placement

Accepted Answer

V4 is placed at the fifth intercostal space at the midclavicular line. Locate V4 before filling in V3 between V2 and V4.

Question 20

V3 Placement

Accepted Answer

V3 is placed midway between V2 and V4. It should not be guessed before accurate V2 and V4 landmarks are established.

Question 21

V5 and V6 Placement

Accepted Answer

V5 is placed at the anterior axillary line level with V4. V6 is placed at the midaxillary line level with V4 and V5.

Question 22

Lead Misplacement Risk

Accepted Answer

Misplaced leads can change ST segments, R-wave progression, axis appearance, and rhythm interpretation. If placement is questionable, correct it before printing a final tracing.

Question 23

Standard Calibration

Accepted Answer

Standard EKG calibration is commonly 10 mm per mV and 25 mm per second. Confirm machine settings and document nonstandard settings if used.

Question 24

Baseline Wander

Accepted Answer

Baseline wander is a slow drifting baseline often caused by movement, breathing, poor electrode contact, or loose leads. Fix the cause before accepting the tracing.

Question 25

Muscle Artifact

Accepted Answer

Muscle artifact creates rough, irregular interference from tension, shivering, tremor, or movement. Help the patient relax, stay warm, and remain still.

Question 26

AC Interference

Accepted Answer

AC interference often appears as regular fine spikes or fuzz from electrical sources. Check grounding, cable placement, nearby devices, and equipment connections.

Question 27

Somatic Tremor

Accepted Answer

Somatic tremor artifact can resemble rhythm irregularity. The technician should reduce motion where possible and avoid treating artifact as a diagnosis.

Question 28

Lead Reversal Clue

Accepted Answer

Unexpected waveform patterns or axis changes can suggest lead reversal. Recheck cable labels and electrode placement before escalating a poor-quality tracing.

Question 29

Print Quality Review

Accepted Answer

Before sending the tracing, check patient identifiers, date and time, calibration, lead quality, artifacts, and whether the recording is complete.

Question 30

Holter Monitor Role

Accepted Answer

Holter monitoring records cardiac activity over an extended period. Technician duties include correct setup, patient instructions, diary guidance, and return instructions.

Question 31

Stress Test Support

Accepted Answer

During stress testing, the technician follows protocol, monitors tracing quality, reports symptoms or concerning changes, and supports patient safety under supervision.

Question 32

Cardiac Conduction Pathway

Accepted Answer

Normal conduction starts at the SA node, travels through the atria to the AV node, then through the His-Purkinje system to the ventricles.

Question 33

P Wave

Accepted Answer

The P wave represents atrial depolarization. In rhythm review, look for whether P waves are present, consistent, and related to QRS complexes.

Question 34

PR Interval

Accepted Answer

The PR interval reflects atrial-to-ventricular conduction time. Abnormal PR patterns can point toward conduction delay or pre-excitation patterns that require provider review.

Question 35

QRS Complex

Accepted Answer

The QRS complex represents ventricular depolarization. Width, shape, and regularity help distinguish narrow-complex from wide-complex rhythms.

Question 36

T Wave

Accepted Answer

The T wave represents ventricular repolarization. Changes may be clinically important, but a CET should report findings through protocol rather than diagnose independently.

Question 37

Regularity Check

Accepted Answer

Compare R-R intervals to decide whether the rhythm is regular or irregular. Regularity is one of the first steps before naming a rhythm pattern.

Question 38

Rate Estimation

Accepted Answer

Rate can be estimated from the EKG grid or counted over a defined strip length. Use a consistent method and recheck if the rhythm is irregular.

Question 39

Sinus Rhythm Clues

Accepted Answer

Sinus rhythm usually has a consistent P wave before each QRS with a regular relationship. Confirm rate and regularity before labeling the rhythm.

Question 40

Sinus Bradycardia and Tachycardia

Accepted Answer

Bradycardia is slower than expected and tachycardia is faster than expected. The technician should connect rate findings to symptoms and escalation rules.

Question 41

Atrial Fibrillation Pattern

Accepted Answer

Atrial fibrillation is associated with irregularly irregular ventricular rhythm and absent consistent P waves. Report according to protocol, especially with symptoms or new onset.

Question 42

Atrial Flutter Pattern

Accepted Answer

Atrial flutter often has repetitive flutter waves with a patterned ventricular response. Confirm tracing quality before assuming the pattern is not artifact.

Question 43

Premature Ventricular Complex

Accepted Answer

A PVC is an early wide ventricular beat that interrupts the rhythm. Note frequency, pattern, patient symptoms, and reporting requirements.

Question 44

Ventricular Tachycardia Concern

Accepted Answer

A sustained wide-complex fast rhythm can be an emergency. The technician should check the patient and activate the appropriate response rather than only print another strip.

Question 45

AV Block Screening

Accepted Answer

AV block review focuses on the relationship between P waves and QRS complexes. Look for PR prolongation, dropped beats, or dissociation patterns.

Question 46

ST Segment Awareness

Accepted Answer

ST segment changes can be clinically urgent. A CET should recognize concerning changes, verify lead placement and tracing quality, and escalate through protocol.

Question 47

QT Interval Awareness

Accepted Answer

The QT interval reflects ventricular depolarization and repolarization time. Marked prolongation may be important, but interpretation belongs in the reporting workflow.

Question 48

Pacemaker Spikes

Accepted Answer

Pacemaker spikes should be evaluated for capture and rhythm context. Technician duties include acquiring a clear tracing and reporting abnormal or concerning patterns.

Question 49

CET Error Log

Accepted Answer

After each missed question, label the cause: lead placement, artifact, safety rule, rhythm clue, documentation, or pacing. Then write the cue you will look for next time.

Question 50

Final CET Review

Accepted Answer

Final review should mix lead placement, acquisition quality, artifact control, and rhythm basics under time. Read the task before looking at answer choices.
