NHA CET Practice Test

Answer choices

1. A. It is within the expected 0.12-0.20 second range
2. B. It cannot be assessed unless the QRS is wide
3. C. It is prolonged above the expected range
4. D. It is shortened below the expected range

Wrong-answer review

• B. It cannot be assessed unless the QRS is wide: Incorrect. PR duration can be measured independently of whether the QRS is narrow or wide.
• C. It is prolonged above the expected range: Incorrect. 0.16 second is not above 0.20 second.
• D. It is shortened below the expected range: Incorrect. 0.16 second is not below 0.12 second.

Answer choices

1. A. Third-degree (complete) AV block
2. B. First-degree AV block
3. C. Atrial fibrillation
4. D. Mobitz I second-degree AV block

Answer choices

1. A. Start the test and learn the controls while the patient exercises before continuing with the remainder of the scheduled test
2. B. Use the old system's steps even if the controls differ
3. C. State the training limitation and obtain appropriately trained assistance before operating the unfamiliar system
4. D. Ask the patient whether the setup looks familiar

Answer choices

1. A. Midway between V2 and V4
2. B. Fourth intercostal space at the left sternal border
3. C. Fifth intercostal space at the left anterior axillary line
4. D. Fourth intercostal space at the right sternal border

Answer choices

1. A. A pattern that can indicate acute myocardial injury and requires prompt clinical communication
2. B. Document acute myocardial infarction based on the contiguous ST elevation and tell the patient what the tracing shows
3. C. Repeat the tracing at lower gain because the ST elevation may reflect excessive amplitude scaling
4. D. Treat the pattern as early repolarization unless reciprocal changes are also visible

Answer choices

1. A. Upload the tracing first and correct the chart later if needed before making any technical correction to the study
2. B. Choose the first matching name in the EHR
3. C. Use room number as the only identifier
4. D. Verify patient identity and attach the tracing to the correct record

Answer choices

1. A. Remove the duplicate V4 channel from the export and send the remaining 11 leads with a note
2. B. Relabel one V4 as V5 if its morphology looks consistent with the expected V5 pattern
3. C. Send the tracing if the automated interpretation reports no acute abnormality despite the duplicate label
4. D. Verify connections/configuration, correct the problem, and obtain a complete correctly labeled tracing

Answer choices

1. A. Silence the alarm and observe the patient briefly before checking electrode and lead integrity
2. B. Activate the ventricular-fibrillation response before correlating the monitor pattern with the patient
3. C. Begin chest compressions while another staff member verifies the monitor leads
4. D. Assess the patient and rapidly verify the electrodes and leads because artifact may be mimicking a lethal rhythm

Answer choices

1. A. Remove the monitor whenever symptoms begin
2. B. Record the time, activity, and symptoms in the diary as instructed
3. C. Avoid all normal activity so the tracing stays perfectly quiet
4. D. Write only the most severe symptom at the end of the monitoring period

Answer choices

1. A. Remove the machine from patient use and follow the facility process for technical service
2. B. Restore the machine to a commonly used default configuration and repeat the self-test
3. C. Open the machine and repair internal circuitry without authorization
4. D. Continue using it if the tracing looks plausible
