BayCare EKG Test Actual Questions and
Verified Answers | Competency Exam Prep
| Graded A+
1. A patient’s ECG shows a regular rhythm with a rate of 72 bpm, P waves
before each QRS, and PR interval of 0.16 sec. What rhythm is this?
A. Atrial fibrillation
B. Normal sinus rhythm
C. Junctional rhythm
D. Ventricular tachycardia
Answer: B
Rationale: Regular rate 60–100 bpm, P wave before each QRS, normal PR → NSR.
2. Which EKG change indicates myocardial ischemia?
A. ST-segment elevation
B. ST-segment depression
C. Wide QRS
D. Tall P waves
Answer: B
Rationale: ST depression = ischemia; ST elevation = injury/MI.
3. PVCs (Premature Ventricular Contractions) appear as:
A. Narrow QRS with P wave
B. Wide QRS, no P wave
C. ST depression
D. PR interval prolongation
Answer: B
Rationale: PVCs originate in ventricles → wide, bizarre QRS without P wave.
,4. A patient has atrial fibrillation. Priority assessment:
A. Blood pressure
B. Apical pulse
C. Respiratory rate
D. Oxygen saturation
Answer: B
Rationale: Irregularly irregular rhythm → apical pulse needed for accurate rate.
5. Heart rate calculation – regular rhythm:
EKG shows 12 large boxes between R waves. What’s the rate?
A. 50 bpm
B. 60 bpm
C. 100 bpm
D. 25 bpm
Answer: A
Rationale: 300 ÷ 6 = 50 bpm (each large box = 0.2 sec).
6. First-degree AV block is identified by:
A. PR interval > 0.20 sec
B. P wave absent
C. QRS > 0.12 sec
D. No relationship between P and QRS
Answer: A
Rationale: PR interval prolonged, every P followed by QRS.
7. Second-degree AV block type I (Wenckebach) features:
A. Progressive PR lengthening until QRS drops
B. Constant PR interval with occasional dropped QRS
C. No P-QRS relationship
D. Irregular P waves
, Answer: A
8. Third-degree AV block is characterized by:
A. Normal PR interval
B. Dropped QRS occasionally
C. No relationship between P and QRS
D. Narrow QRS
Answer: C
Rationale: Complete heart block → atria and ventricles beat independently.
9. Ventricular tachycardia is:
A. Narrow QRS, regular rhythm
B. Wide QRS, rapid rate
C. Irregular P waves
D. ST depression
Answer: B
10. EKG of STEMI typically shows:
A. ST elevation in contiguous leads
B. ST depression
C. Peaked T waves
D. Wide PR interval
Answer: A
11. T wave inversion indicates:
A. Normal variant
B. Ischemia
C. MI
D. Bradycardia
Answer: B
