NCAL KAISER EKG EXAM COMPLETE 300
QUESTIONS WITH DETAILED SOLUTIONS JUST
RELEASED THIS YEAR
NCAL KAISER EKG EXAM – COMPREHESTUDY PRACTICE BANK
EXAM COVERAGE SUMMARY
This comprehensive review covers all core EKG interpretation competencies required for the
NCAL Kaiser EKG examination: cardiac electrophysiology and conduction pathways (SA node,
AV node, bundle branches, Purkinje fibers); waveform identification and measurement (P
wave, QRS complex, T wave, PR interval, QRS duration, QT interval); sinus rhythms (normal
sinus, sinus bradycardia, sinus tachycardia, sinus arrhythmia); atrial dysrhythmias (PACs, atrial
flutter, atrial fibrillation, SVT, PSVT); junctional rhythms (junctional escape, accelerated
junctional, junctional tachycardia); AV blocks (first-degree, second-degree Mobitz
I/Wenckebach, second-degree Mobitz II, third-degree/complete heart block); ventricular
dysrhythmias (PVCs, ventricular tachycardia, torsades de pointes, ventricular
fibrillation); pacemaker rhythms and malfunction; 12-lead EKG interpretation (lead placement,
axis, ischemia, injury, infarction patterns); ACLS pharmacology and interventions (adenosine,
amiodarone, atropine, dopamine, epinephrine, defibrillation, cardioversion, transcutaneous
pacing); electrolyte imbalances (hyperkalemia, hypokalemia, hypomagnesemia); medication
effects and toxicities (digoxin, beta-blockers, calcium channel blockers, QT-prolonging
drugs); hemodynamic assessment and nursing priorities; and emergency cardiac care
protocols.
300 RANDOMIZED EXAM-STYLE QUESTIONS
Question 1: A patient's telemetry monitor displays a regular rhythm at 88 beats per minute with
a P wave preceding every QRS complex. The PR interval measures 0.16 seconds and the QRS
duration is 0.08 seconds. What is the most appropriate interpretation?

A) Sinus bradycardia
B) Normal sinus rhythm
C) First-degree AV block
D) Sinus tachycardia
Answer: B
Normal sinus rhythm requires a rate of 60-100 bpm with regular rhythm, normal P waves
preceding each QRS, PR interval 0.12-0.20 seconds, and QRS less than 0.12 seconds; all criteria
are met here.
Question 2: The nurse notes a heart rate of 42 beats per minute on the cardiac monitor. The
rhythm is regular with normal P waves and QRS complexes. The patient is asymptomatic with
stable vital signs. Which action should the nurse take first?
A) Prepare for transcutaneous pacing
B) Administer atropine 0.5 mg IV push
C) Continue to monitor and assess the patient
D) Notify the provider immediately

Answer: C
Asymptomatic sinus bradycardia does not require immediate intervention; the priority is
continued monitoring and assessment while identifying potentially reversible causes. Treatment
is indicated only if the patient is hemodynamically unstable.
Question 3: Which EKG waveform represents ventricular depolarization?
A) P wave
B) QRS complex
C) T wave
D) U wave
Answer: B
The QRS complex represents ventricular depolarization (contraction). The P wave represents
atrial depolarization, and the T wave represents ventricular repolarization.
Question 4: A patient with atrial fibrillation has a ventricular rate of 140 beats per minute and is
experiencing shortness of breath and chest discomfort. What is the priority nursing action?
A) Administer oral anticoagulation

B) Prepare for synchronized cardioversion
C) Apply oxygen and assess hemodynamic status
D) Administer adenosine 6 mg rapid IV push
Answer: C
The priority is to assess and stabilize the patient's hemodynamic status with oxygen and further
evaluation. Adenosine is not effective for atrial fibrillation. Synchronized cardioversion may be
indicated for unstable patients but requires prior assessment.
Question 5: The PR interval on an EKG strip measures 0.28 seconds. All other intervals are
normal and the patient is asymptomatic. What is the most likely rhythm?
A) Normal sinus rhythm
B) First-degree AV block
C) Second-degree AV block Type I
D) Third-degree heart block
Answer: B
First-degree AV block is defined by a PR interval greater than 0.20 seconds with all P waves
