NCAL KAISER EKG ACTUAL EXAM TEST BANK 2026 | COMPLETE
QUESTIONS AND VERIFIED ANSWERS
Questions 1–200
1. What is the normal rate for the SA node?
A) 20-40 bpm
B) 60-100 bpm
C) 40-60 bpm
D) 100-150 bpm
Answer B: 60-100 bpm
Rationale: The SA node is the primary pacemaker of the heart, firing
at 60-100 bpm.
,2. The P wave on an EKG represents:
A) Ventricular depolarization
B) Atrial depolarization
C) Ventricular repolarization
D) Atrial repolarization
Answer B: Atrial depolarization
Rationale: The P wave represents atrial depolarization, the electrical
activation of the atria.
3. The QRS complex on an EKG represents:
A) Atrial depolarization
B) Ventricular depolarization
C) Ventricular repolarization
D) Atrial repolarization
Answer B: Ventricular depolarization
Rationale: The QRS complex represents ventricular depolarization,
the electrical activation of the ventricles.
4. The T wave on an EKG represents:
,A) Atrial depolarization
B) Ventricular depolarization
C) Ventricular repolarization
D) Atrial repolarization
Answer C: Ventricular repolarization
Rationale: The T wave represents ventricular repolarization, the
recovery phase of the ventricles.
5. What is the normal rate for the AV node?
A) 60-100 bpm
B) 40-60 bpm
C) 20-40 bpm
D) 10-20 bpm
Answer B: 40-60 bpm
Rationale: The AV node is the secondary pacemaker, firing at 40-60
bpm.
6. What is the normal rate for the Purkinje fibers/ventricles?
A) 60-100 bpm
, B) 40-60 bpm
C) 20-40 bpm
D) 10-20 bpm
Answer C: 20-40 bpm
Rationale: The Purkinje fibers fire at the slowest rate of 20-40 bpm as
a last-resort pacemaker.
7. Each small box on EKG paper represents how many seconds?
A) 0.20 seconds
B) 0.04 seconds
C) 0.10 seconds
D) 0.50 seconds
Answer B: 0.04 seconds
Rationale: Each small box on EKG paper represents 0.04 seconds (1
mm).
8. Each large box on EKG paper represents how many seconds?
A) 0.04 seconds
B) 0.20 seconds
