BayCare EKG Competency Exam 2026/2027 | 2 Versions|
Real Questions with Correct Answers in Bold |
Comprehensive Study Guide with Clinical Explanations |
Updated for Current Testing Cycle
⭐⭐⭐⭐⭐ "Passed on my first attempt!"
"I was so nervous about the EKG competency because rhythm interpretation has always
been my weak spot. This test bank was a game-changer. The questions were structured
exactly like the actual exam, and having the answers in bold made it easy to test myself
repeatedly. I passed with flying colors! Worth every penny."

This comprehensive study guide contains actual BayCare EKG competency test questions and verified answers for
the 2026/2027 testing cycle. Each question is presented in multiple-choice format with the correct answer in
bold and a detailed clinical rationale in italics. Topics include rhythm identification, heart blocks, myocardial infarction
patterns, electrolyte abnormalities, ACLS treatment algorithms, and EKG measurement interpretation. Updated for
the current exam cycle. Perfect for nurses, monitor technicians, medical students, and allied health professionals
preparing for the BayCare EKG certification exam.
1. A 68-year-old male presents with palpitations. His EKG shows an irregularly
irregular rhythm with no discernible P waves. What is the most likely rhythm?
A) Atrial flutter
B) Sinus arrhythmia
C) Atrial fibrillation
,D) Multifocal atrial tachycardia
Atrial fibrillation is defined by chaotic atrial activity, absent P waves, and an irregularly
irregular ventricular response.
2. Which of the following PR interval durations is consistent with first-degree heart
block?
A) 0.16 seconds
B) 0.18 seconds
C) 0.20 seconds
D) 0.24 seconds
*First-degree heart block is diagnosed when the PR interval exceeds 0.20 seconds,
indicating delayed AV nodal conduction.*
3. A patient's EKG reveals a regular rhythm with a heart rate of 42 bpm, normal P
waves preceding each QRS, and a PR interval of 0.18 seconds. What is the correct
interpretation?
A) Sinus bradycardia
B) Junctional rhythm
C) Second-degree heart block type I
D) Sinus arrest
Sinus bradycardia is a sinus rhythm with a rate below 60 bpm; the presence of normal P
waves preceding each QRS confirms the sinus node as the pacemaker.
4. Which EKG finding is most characteristic of hyperkalemia?
A) U waves
B) Peaked T waves
C) ST elevation
D) Prolonged QT interval
Peaked, tented T waves are an early and classic sign of hyperkalemia, resulting from
altered repolarization due to elevated serum potassium.
, 5. In second-degree heart block type I (Wenckebach), which of the following patterns
is typically observed?
A) Constant PR interval with intermittent dropped QRS complexes
B) Progressively lengthening PR intervals until a QRS is dropped
C) Fixed PR interval with a constant ventricular rate
D) No relationship between P waves and QRS complexes
Wenckebach is characterized by progressive PR prolongation due to gradual AV node
fatigue until a beat is non-conducted.
6. A patient's EKG shows a regular rhythm with a heart rate of 150 bpm, narrow QRS
complexes, and visible P waves buried in the preceding T waves. What is the most
likely rhythm?
A) Atrial fibrillation
B) Ventricular tachycardia
C) Sinus tachycardia
D) Atrial flutter with 2:1 conduction
Sinus tachycardia originates from the sinus node with a rate exceeding 100 bpm; P waves
are often buried in T waves at higher rates but remain present.
7. What is the QRS duration threshold for defining a wide complex tachycardia?
A) >0.08 seconds
B) >0.10 seconds
C) >0.12 seconds
D) >0.14 seconds
A QRS duration greater than 0.12 seconds indicates aberrant ventricular conduction or a
ventricular origin, distinguishing wide complex tachycardias.
8. Which of the following is the correct EKG finding in ST-segment elevation
myocardial infarction (STEMI)?
A) ST-segment depression
B) ST-segment elevation in two contiguous leads
C) T wave inversion
