Questions & Answers with Rationales | 2026
Study Guide
1. Which of the following are considered lethal cardiac rhythms?
(Select all that apply)
A) Normal Sinus Rhythm
B) Ventricular Fibrillation
C) Atrial Flutter
D) Asystole
E) Pulseless Electrical Activity (PEA)
Answer: B, D, E
Rationale: The 7 lethal rhythms are: V-fib, V-tach, asystole, PEA,
idioventricular, 2nd degree Type 2, and complete heart block. These
rhythms are life-threatening and require immediate intervention.
2. A client presents with a rhythm showing no identifiable P waves,
wide QRS complexes, and a rate of 35 bpm. The nurse identifies this
as:
A) Ventricular tachycardia
B) Idioventricular rhythm
C) Atrial fibrillation
D) Junctional rhythm
,Answer: B
Rationale: Idioventricular rhythm is characterized by no P waves, wide QRS
complexes, and T waves in the opposite direction. The rate is less than 40
bpm.
3. The nurse is caring for a client with a rhythm that shows no P
waves, chaotic waves, and no identifiable QRS complexes. The nurse
should prepare for:
A) Synchronized cardioversion
B) Defibrillation
C) Atropine administration
D) Pacing
Answer: B
Rationale: Ventricular fibrillation (V-fib) is a lethal rhythm characterized by
chaotic waves with no identifiable P waves or QRS complexes. The
treatment is immediate defibrillation.
Normal Sinus Rhythm and Sinus Dysrhythmias
4. Which of the following describes Normal Sinus Rhythm (NSR)?
A) Rate < 60 bpm, regular rhythm
B) Rate 60-100 bpm, regular rhythm, P waves before each QRS
C) Rate > 100 bpm, irregular rhythm
D) Rate 40-60 bpm, P waves inverted
, Answer: B
Rationale: Normal Sinus Rhythm (NSR) has a rate of 60-100 bpm with
regular rhythm and P waves preceding each QRS complex.
5. A client's cardiac monitor shows a heart rate of 52 bpm with a
regular rhythm and normal P waves. The nurse identifies this as:
A) Normal sinus rhythm
B) Sinus bradycardia
C) Sinus arrhythmia
D) Junctional rhythm
Answer: B
Rationale: Sinus bradycardia is defined as a heart rate less than 60 bpm.
Treatment includes pacing, atropine, and treating reversible causes.
6. A client has a heart rate of 140 bpm with regular rhythm and
normal P waves. The nurse should:
A) Prepare for immediate cardioversion
B) Identify and treat the underlying cause
C) Administer atropine
D) Prepare for defibrillation
Answer: B
Rationale: Sinus tachycardia is defined as a heart rate greater than 100
bpm and less than 160 bpm. Treatment involves identifying and treating
the underlying cause.
