HOW TO USE THIS GUIDE
This document contains the complete 35-question Relias Dysrhythmia Basic A Exam with verified correct
answers and detailed rationales for each rhythm strip. Each question includes the ECG strip description as it
appears on the actual exam.
SECTION 1: SINUS RHYTHMS
Question 1
ECG Strip Description: A 6-second strip showing 8 QRS complexes. The rhythm is regular, with a normal P
wave before each QRS. The PR interval is 0.16 seconds, and the QRS is narrow. What is the rhythm?
Correct Answer: A) Normal Sinus Rhythm
Rationale: The rate is 8 × 10 = 80 bpm (normal 60-100). The rhythm is regular with normal P waves, normal
PR interval (0.12-0.20), and narrow QRS. This meets all criteria for Normal Sinus Rhythm.
Question 2
ECG Strip Description: A patient presents with a heart rate of 48 bpm, regular rhythm, normal P waves, and
normal PR and QRS intervals. The patient is asymptomatic. What is the most appropriate action?
Correct Answer: C) Continue to monitor
Rationale: Sinus Bradycardia is defined as a rate <60 bpm with all other NSR criteria. In an asymptomatic
patient, this is often a normal finding (e.g., athletes, during sleep). Treatment is only indicated if the patient is
symptomatic (hypotension, dizziness, chest pain, altered mental status).
Question 3
ECG Strip Description: A patient has a heart rate of 130 bpm, regular rhythm, normal P waves before each
QRS, normal PR interval, and narrow QRS. The patient reports anxiety and palpitations. What is the rhythm
and what is the priority intervention?

ANSWERS | DETAILED RATIONALES | PASS GUARANTEED – A+ GRADED
Correct Answer: A) Sinus Tachycardia; treat the underlying cause
Rationale: Sinus Tachycardia is defined as a rate >100 bpm with all other NSR criteria. It is a compensatory
response to a stressor (fever, pain, dehydration, anemia, heart failure). The priority is to identify and treat the
underlying cause. Do NOT treat the rate itself unless it is causing hemodynamic instability.
Question 4
ECG Strip Description: The rhythm is regular with a rate of 62 bpm. P waves are present and upright before
each QRS. PR interval is 0.18 seconds. What is the rhythm?
Correct Answer: A) Normal Sinus Rhythm
Rationale: Rate of 62 bpm falls within normal range of 60-100 bpm, with normal P waves = Normal Sinus
Rhythm.
Question 5
ECG Strip Description: A patient's heart rate drops to 42 bpm during sleep. The rhythm is regular with
normal P waves. What is the rhythm?
Correct Answer: A) Sinus Bradycardia
Rationale: Sinus Bradycardia is a rate <60 bpm with all other NSR criteria. During sleep, heart rate naturally
decreases due to increased parasympathetic tone. This is a normal physiological response.
Question 6
ECG Strip Description: A patient's ECG shows a rate of 55 bpm, regular rhythm, and normal P waves. The
patient is dizzy and hypotensive. What is the priority intervention?
