Current Prep Cycle

NHA active test plan usage

NHA's current CET test plan lists a 120-item exam (100 scored + 20 pretest) with a 2-hour testing window and three weighted domains: Safety & Compliance (32%), EKG Acquisition (44%), and EKG Analysis/Interpretation (24%). NHA candidate scoring guidance uses a 200-500 scale with 390 as the passing standard for handbook-covered exams.

1For a standard diagnostic ECG, where is lead V1 placed?
A.4th intercostal space at the right sternal border
B.4th intercostal space at the left sternal border
C.midway between V2 and V4
D.5th intercostal space at the left midclavicular line
Explanation: Correct electrode landmarks reduce false ST/T changes and improve diagnostic reliability. V1 should be placed at 4th intercostal space at the right sternal border.
2Lead V1 is placed one intercostal space too high. What is the MOST likely consequence?
A.No effect if heart rate stays unchanged
B.Waveform distortion that can mimic ischemia or abnormal conduction
C.Automatic monitor calibration failure every time
D.Only blood pressure values become inaccurate
Explanation: Incorrect lead placement is a common preventable source of false ECG findings. Misplaced chest or limb leads can create pseudo-ischemic or pseudo-conduction abnormalities.
3For a standard diagnostic ECG, where is lead V2 placed?
A.midway between V2 and V4
B.4th intercostal space at the right sternal border
C.4th intercostal space at the left sternal border
D.5th intercostal space at the left midclavicular line
Explanation: Correct electrode landmarks reduce false ST/T changes and improve diagnostic reliability. V2 should be placed at 4th intercostal space at the left sternal border.
4Lead V2 is placed one intercostal space too high. What is the MOST likely consequence?
A.Only blood pressure values become inaccurate
B.No effect if heart rate stays unchanged
C.Automatic monitor calibration failure every time
D.Waveform distortion that can mimic ischemia or abnormal conduction
Explanation: Incorrect lead placement is a common preventable source of false ECG findings. Misplaced chest or limb leads can create pseudo-ischemic or pseudo-conduction abnormalities.
5For a standard diagnostic ECG, where is lead V3 placed?
A.4th intercostal space at the right sternal border
B.4th intercostal space at the left sternal border
C.5th intercostal space at the left midclavicular line
D.midway between V2 and V4
Explanation: Correct electrode landmarks reduce false ST/T changes and improve diagnostic reliability. V3 should be placed at midway between V2 and V4.
6Lead V3 is placed one intercostal space too high. What is the MOST likely consequence?
A.Automatic monitor calibration failure every time
B.Only blood pressure values become inaccurate
C.Waveform distortion that can mimic ischemia or abnormal conduction
D.No effect if heart rate stays unchanged
Explanation: Incorrect lead placement is a common preventable source of false ECG findings. Misplaced chest or limb leads can create pseudo-ischemic or pseudo-conduction abnormalities.
7For a standard diagnostic ECG, where is lead V4 placed?
A.midway between V2 and V4
B.5th intercostal space at the left midclavicular line
C.4th intercostal space at the right sternal border
D.4th intercostal space at the left sternal border
Explanation: Correct electrode landmarks reduce false ST/T changes and improve diagnostic reliability. V4 should be placed at 5th intercostal space at the left midclavicular line.
8Lead V4 is placed one intercostal space too high. What is the MOST likely consequence?
A.Waveform distortion that can mimic ischemia or abnormal conduction
B.No effect if heart rate stays unchanged
C.Automatic monitor calibration failure every time
D.Only blood pressure values become inaccurate
Explanation: Incorrect lead placement is a common preventable source of false ECG findings. Misplaced chest or limb leads can create pseudo-ischemic or pseudo-conduction abnormalities.
9For a standard diagnostic ECG, where is lead V5 placed?
A.4th intercostal space at the right sternal border
B.left anterior axillary line at the same horizontal level as V4
C.4th intercostal space at the left sternal border
D.midway between V2 and V4
Explanation: Correct electrode landmarks reduce false ST/T changes and improve diagnostic reliability. V5 should be placed at left anterior axillary line at the same horizontal level as V4.
10Lead V5 is placed one intercostal space too high. What is the MOST likely consequence?
A.Automatic monitor calibration failure every time
B.No effect if heart rate stays unchanged
C.Waveform distortion that can mimic ischemia or abnormal conduction
D.Only blood pressure values become inaccurate
Explanation: Incorrect lead placement is a common preventable source of false ECG findings. Misplaced chest or limb leads can create pseudo-ischemic or pseudo-conduction abnormalities.

NHA EKG Technician Study Tips from Top Performers

1Prioritize EKG acquisition first because it's the largest weighted domain
2Memorize exact chest-lead landmarks (V1-V6) and common lead-reversal patterns
3Use a fixed rhythm method: rate, regularity, P waves, PR interval, QRS width, then interpretation
4Practice artifact troubleshooting (muscle tremor, loose leads, wandering baseline, AC interference)
5Treat patient identification and infection-control steps as scored workflow decisions, not optional steps
6Run timed mixed sets to build pace for a 2-hour, 120-item exam session

Frequently Asked Questions

How many questions are on the NHA CET exam?

NHA's published CET test plan describes 120 total items: 100 scored questions and 20 unscored pretest items.

How long is the NHA CET exam?

The CET exam is timed for 2 hours (120 minutes).

What score do I need to pass CET?

NHA uses scaled scoring for handbook-covered exams and lists 390 (on a 200-500 scale) as the passing standard.

What are the CET content domains?

NHA's CET blueprint is Safety & Compliance (32%), EKG Acquisition (44%), and EKG Analysis/Interpretation (24%). Acquisition is the largest section, so lead placement and artifact control should dominate your prep plan.

How should I prepare for CET in 2026?

Use blueprint-weighted prep: 1) master acquisition first, especially chest lead landmarks and artifact troubleshooting, 2) drill rhythm method with rate/regularity/P-wave/QRS checks, and 3) rehearse patient-ID and safety workflows so they become automatic on scenario questions.

Is CET the same as monitor tech training?

They overlap, but CET specifically tests entry-level competencies defined in NHA's test plan, including acquisition workflow, safety/compliance, and interpretation basics rather than advanced telemetry-only analysis.
