ADVENT HEALTH EKG EXAM QUESTIONS
WITH CORRECT ANSWERS 2026 UPDATE
Question 1

A patient’s EKG shows upright P waves before each QRS, rate 72 bpm, PR interval 0.18 sec.
What is the rhythm?

• A. Atrial fibrillation
• B. Normal sinus rhythm ✅
• C. Junctional rhythm
• D. Ventricular tachycardia

Rationale: Upright P waves with normal PR and rate = sinus rhythm.

Question 2

Which finding is most characteristic of atrial fibrillation?

• A. Sawtooth flutter waves
• B. Regular rhythm with P waves
• C. Irregularly irregular rhythm without distinct P waves ✅
• D. Wide QRS complexes

Rationale: AFib = chaotic atrial activity, no clear P waves, irregular rhythm.

Question 3

PR interval >0.20 sec but all impulses conducted. Diagnosis?

• A. Mobitz I
• B. Mobitz II
• C. First-degree AV block ✅
• D. Third-degree AV block

Rationale: Prolonged PR with all conduction = first-degree block.

Question 4

Wide QRS at 160 bpm, no P waves, regular rhythm. Rhythm?

• A. SVT
• B. Atrial flutter

, • C. Ventricular tachycardia ✅
• D. Sinus tachycardia

Rationale: Wide QRS + fast regular rhythm = VT.

Question 5

Most dangerous complication of ventricular fibrillation?

• A. Bradycardia
• B. Stroke
• C. Cardiac arrest ✅
• D. Atrial enlargement

Rationale: VF = no cardiac output → cardiac arrest.

Question 6

Which rhythm shows sawtooth waves at ~300 bpm atrial rate?

• A. AFib
• B. Atrial flutter ✅
• C. VT
• D. Sinus tachycardia

Rationale: Flutter waves = atrial flutter.

Question 7

A run of ≥3 PVCs at >100 bpm is called:

• A. Bigeminy
• B. Couplets
• C. Ventricular tachycardia ✅
• D. Junctional rhythm

Rationale: ≥3 PVCs in succession = VT.

Question 8

ST elevation in contiguous leads suggests:

• A. Pericarditis
• B. Myocardial infarction ✅
• C. Hypokalemia

, • D. AFib

Rationale: ST elevation = acute MI.

Question 9

QT prolongation increases risk of:

• A. AFib
• B. Torsades de pointes ✅
• C. Sinus bradycardia
• D. AV block

Rationale: Long QT predisposes to torsades.

Question 10

Which electrolyte imbalance causes peaked T waves?

• A. Hypokalemia
• B. Hyperkalemia ✅
• C. Hypocalcemia
• D. Hyponatremia

Rationale: Hyperkalemia = tall peaked T waves.

Question 11

Which rhythm shows complete AV dissociation?

• A. Mobitz I
• B. Mobitz II
• C. Third-degree AV block ✅
• D. First-degree AV block

Rationale: Complete block = atria and ventricles independent.

Question 12

Which rhythm is most likely with narrow QRS, rate 180 bpm, no visible P waves?

• A. VT
• B. Supraventricular tachycardia (SVT) ✅
• C. AFib
• D. Sinus tachycardia

, Rationale: Narrow QRS + fast regular rhythm = SVT.

Question 13

Which rhythm shows progressive PR lengthening until a beat is dropped?

• A. Mobitz II
• B. Mobitz I (Wenckebach) ✅
• C. First-degree block
• D. Third-degree block

Rationale: Wenckebach = progressive PR prolongation.

Question 14

Which rhythm shows sudden dropped QRS without PR prolongation?

• A. Mobitz I
• B. Mobitz II ✅
• C. First-degree block
• D. Third-degree block

Rationale: Mobitz II = dropped beats without PR change.

Question 15

Which rhythm shows chaotic baseline, no QRS, no P waves?

• A. AFib
• B. VT
• C. Ventricular fibrillation ✅
• D. Flutter

Rationale: VF = chaotic baseline, no organized activity.

Question 16

Which rhythm shows early wide QRS beats interrupting sinus rhythm?

• A. PACs
• B. PVCs ✅
• C. VT
• D. AFib

Rationale: PVCs = premature ventricular contractions.
