,1. The monitor alarms - ventricular fibrillation with chaotic baseline, no identifiable QRS. The
immediate action is The patient is on cardiac monitor, vital signs stable/unstable. What is the
most appropriate nursing identification and intervention per Relias and AHA guidelines?
A. Fail to activate emergency response
B. Give adenosine for complete heart block
C. Confuse SVT with atrial flutter
D. Ventricular fibrillation - initiate CPR and defibrillation per ACLS
Answer: D
Rationale: This option reflects evidence-based ACLS and Relias competency standards for safe dysrhythmia
management. It prioritizes assessment, recognizes lethal rhythms, and implements correct emergency
response including oxygen, monitoring, medications, defibrillation, and provider notification. Distractors delay
care, use contraindicated drugs, or fail to recognize instability. Knowledge of causes, treatments, and
documentation is critical for passing and for patient safety in clinical practice. Focus: QRS width.
2. Which finding indicates return of spontaneous circulation after defibrillation for The
patient is on cardiac monitor, vital signs stable/unstable. What is the most appropriate
nursing identification and intervention per Relias and AHA guidelines?
A. Delay intervention and only document
B. Give adenosine for complete heart block
C. Ventricular fibrillation - initiate CPR and defibrillation per ACLS
D. Sinus tachycardia with incorrect rate
Answer: C
Rationale: Selected answer aligns with current ECG interpretation guidelines, electrolyte effects on
myocardium, and 12-lead analysis. It considers ischemia, injury, infarction patterns, and electrolyte-induced
changes while integrating vital signs and patient symptoms. Alternatives demonstrate common errors like
confusing atrial flutter with SVT or missing heart block progression. This concept is frequently tested on Relias
and is vital for competent cardiac monitoring and emergency response. Focus: QRS width.
3. The monitor alarms - ventricular fibrillation with chaotic baseline, no identifiable QRS. The
immediate action is The patient is on cardiac monitor, vital signs stable/unstable. What is the
most appropriate nursing identification and intervention per Relias and AHA guidelines?
A. Normal sinus rhythm - continue monitoring
B. Ignore lethal rhythm
C. Defibrillate a stable sinus rhythm
D. Confuse SVT with atrial flutter
Answer: A
Rationale: This option reflects evidence-based ACLS and Relias competency standards for safe dysrhythmia
management. It prioritizes assessment, recognizes lethal rhythms, and implements correct emergency
response including oxygen, monitoring, medications, defibrillation, and provider notification. Distractors delay
care, use contraindicated drugs, or fail to recognize instability. Knowledge of causes, treatments, and
documentation is critical for passing and for patient safety in clinical practice. Focus: rate regularity.
4. The monitor alarms - ventricular fibrillation with chaotic baseline, no identifiable QRS. The
immediate action is The patient is on cardiac monitor, vital signs stable/unstable. What is the
most appropriate nursing identification and intervention per Relias and AHA guidelines?
A. Atrial fibrillation with RVR - assess, notify provider, consider rate control
, B. Delay intervention and only document
C. Give adenosine for complete heart block
D. Identify asystole incorrectly
Answer: A
Rationale: This option reflects evidence-based ACLS and Relias competency standards for safe dysrhythmia
management. It prioritizes assessment, recognizes lethal rhythms, and implements correct emergency
response including oxygen, monitoring, medications, defibrillation, and provider notification. Distractors delay
care, use contraindicated drugs, or fail to recognize instability. Knowledge of causes, treatments, and
documentation is critical for passing and for patient safety in clinical practice. Focus: P wave analysis.

most appropriate nursing identification and intervention per Relias and AHA guidelines?
A. Delay intervention and only document
B. Administer atropine for ventricular fibrillation
C. Confuse SVT with atrial flutter
D. Third-degree AV block - prepare for transcutaneous pacing
