Question 1 Cardiac anatomy and conduction

Question 1: Cardiac anatomy and conduction

An EKG technician is explaining the cardiac conduction system. Which structure is normally the heart's primary pacemaker?

Question 2 Lead placement

Question 2: Lead placement

An EKG technician is placing the limb electrodes for a 12-lead EKG. Where should the right leg electrode be placed?

Question 3 EKG waveform interpretation

Question 3: EKG waveform interpretation

On a normal EKG tracing, what does the P wave represent?

Question 4 Rhythm interpretation

Question 4: Rhythm interpretation

An EKG technician observes a rhythm strip with an irregularly irregular ventricular rhythm, no identifiable P waves, and a chaotic baseline. Which rhythm does this most likely represent?

Question 5 Heart rate calculation

Question 5: Heart rate calculation

An EKG technician measures a consistent R-to-R interval of 20 small squares on a standard EKG at 25 mm per second. What is the approximate heart rate?

Question 6 Artifacts and troubleshooting

Question 6: Artifacts and troubleshooting

An EKG tracing shows a fuzzy, jagged baseline with rapid small spikes across all leads. The technician suspects this is muscle tremor artifact. What is the best corrective action?

Question 7 Rhythm interpretation and life-threatening rhythms

Question 7: Rhythm interpretation and life-threatening rhythms

An EKG technician sees a rhythm with no identifiable P waves, QRS complexes, or T waves, only a completely chaotic, irregular wavy line. The patient is unresponsive. What does this rhythm most likely represent?

Question 8 EKG technique and standardization

Question 8: EKG technique and standardization

Before recording a 12-lead EKG, an EKG technician verifies the standardization mark. What does a normal standardization mark indicate?

Question 9 Precordial lead placement

Question 9: Precordial lead placement

An EKG technician is placing precordial lead V4. What is the correct anatomical location for V4?

Question 10 PR interval and conduction blocks

Question 10: PR interval and conduction blocks

An EKG technician measures a consistently prolonged PR interval of 0.24 seconds with every P wave followed by a QRS complex. Which conduction abnormality does this represent?

Question 11 Patient preparation

Question 11: Patient preparation

An EKG technician is preparing a patient with excessive chest hair for electrode placement. What is the most appropriate action?

Question 12 Rhythm interpretation

Question 12: Rhythm interpretation

An EKG technician observes a regular rhythm at 45 beats per minute with a normal P wave before each normal QRS complex. How is this rhythm best described?

Question 13 Wandering baseline and artifact

Question 13: Wandering baseline and artifact

An EKG tracing shows the baseline slowly drifting up and down across the strip. This is most likely which type of artifact?

Question 14 Electrical interference

Question 14: Electrical interference

An EKG tracing shows uniform, fine, rapid oscillations of the baseline that appear in every lead. The technician suspects 60-cycle interference. What is the most likely cause?

Question 15 Cardiac anatomy

Question 15: Cardiac anatomy

An EKG technician is studying coronary circulation. Which artery primarily supplies blood to the left ventricle and a large portion of the heart muscle?

Question 16 Holter monitoring

Question 16: Holter monitoring

An EKG technician applies a Holter monitor to a patient. What is the primary purpose of a Holter monitor?

Question 17 Lead reversal

Question 17: Lead reversal

An EKG technician records a tracing and notices that lead I is inverted, with a negative P wave and QRS complex, while the rest of the tracing looks unusual. Which error is the most likely cause?

Question 18 Stress testing

Question 18: Stress testing

An EKG technician is assisting with an exercise stress test. During the test, the patient reports chest pain and the EKG shows significant ST segment changes. What is the appropriate response?

Question 19 QRS complex interpretation

Question 19: QRS complex interpretation

An EKG technician measures a QRS complex duration of 0.16 seconds. The normal QRS duration is 0.06 to 0.10 seconds. What does this widened QRS suggest?

Question 20 Safety and emergency response

Question 20: Safety and emergency response

While an EKG technician is recording a tracing, the patient suddenly becomes unresponsive and the monitor shows a flat line. After confirming the patient is unresponsive and not breathing, what should the technician do first?
