,1. A patient with Mobitz II second-degree block with HR 32 and hypotension requires 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. Third-degree AV block - prepare for transcutaneous pacing
C. Give adenosine for complete heart block
D. Confuse SVT with atrial flutter
Answer: B
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: emergency response.
2. A patient with Mobitz II second-degree block with HR 32 and hypotension requires 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. Third-degree AV block - prepare for transcutaneous pacing
C. Defibrillate a stable sinus rhythm
D. Identify asystole incorrectly
Answer: B
Rationale: Correct because it accurately identifies the dysrhythmia based on rate, regularity, P wave
morphology, PR interval, and QRS width per Relias and AHA ECG criteria. Understanding atrial vs ventricular
origin and conduction blocks is essential. Incorrect options misinterpret key measurements or confuse similar
rhythms. Mastery of 5-step ECG interpretation ensures accurate identification and timely intervention, which is
high-yield for Relias Dysrhythmia Basic Test success. Focus: emergency response.
3. The ECG shows prolonged PR interval 0.24 sec with every P wave conducted. This 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. Ignore lethal rhythm
B. Administer atropine for ventricular fibrillation
C. Sinus tachycardia with incorrect rate
D. Normal sinus rhythm - continue monitoring
Answer: D
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

patient is on cardiac monitor, vital signs stable/unstable. What is the most appropriate
nursing identification and intervention per Relias and AHA guidelines?
A. Ignore lethal rhythm
B. Administer atropine for ventricular fibrillation
C. Ventricular fibrillation - initiate CPR and defibrillation per ACLS
D. Sinus tachycardia with incorrect rate
Answer: C
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: emergency response.
