Studying for the Relias Dysrhythmia Basic A test in 2024 can feel overwhelming, especially if you are a nursing student, a new nurse, or a healthcare professional preparing for certification. Understanding the correct answers for this assessment is not just about passing — it is about building a solid foundation in cardiac rhythm interpretation that will keep your patients safe. This guide breaks down the most common questions, explains the reasoning behind each answer, and helps you approach the test with confidence But it adds up..
What Is the Relias Dysrhythmia Basic A Test?
The Relias Dysrhythmia Basic A exam is an online competency assessment used across many healthcare organizations to evaluate a nurse's ability to recognize and interpret basic cardiac rhythms. It is part of Relias Learning's continuing education platform, which is widely adopted by hospitals, clinics, and long-term care facilities It's one of those things that adds up..
No fluff here — just what actually works.
The test covers foundational ECG concepts including:
- Normal sinus rhythm
- Sinus bradycardia and sinus tachycardia
- Atrial fibrillation and atrial flutter
- Ventricular tachycardia
- Heart blocks (first-degree, second-degree type I and type II, and third-degree)
- Premature complexes (PACs and PVCs)
- Asystole and pulseless electrical activity (PEA)
Each question presents a strip or description of a rhythm, and you must identify the correct rhythm, determine if it is normal or abnormal, and sometimes choose the appropriate nursing intervention But it adds up..
Common Questions and Answers for 2024
Below are some of the most frequently encountered questions from the Relias Dysrhythmia Basic A test, along with detailed explanations so you can understand why each answer is correct Simple as that..
1. A patient's ECG shows a regular rhythm with a heart rate of 72 bpm. Each P wave is followed by a QRS complex, and the PR interval is 0.16 seconds. What rhythm is this?
Answer: Normal Sinus Rhythm
Explanation: Normal sinus rhythm is characterized by a regular rhythm, a heart rate between 60 and 100 bpm, a P wave before every QRS complex, and a PR interval between 0.12 and 0.20 seconds. All of these criteria are met in this scenario, making it a textbook example of normal sinus rhythm.
2. The ECG strip shows irregularly irregular rhythm with no visible P waves and an undulating baseline. The ventricular rate is around 110 bpm. What is the most likely rhythm?
Answer: Atrial Fibrillation
Explanation: Atrial fibrillation (AFib) is defined by an irregularly irregular rhythm, the absence of distinct P waves, and a fibrillatory baseline. The ventricular rate can vary but is often elevated. This is one of the most common dysrhythmias tested on Relias, so recognizing its key features is essential.
3. A rhythm strip reveals a heart rate of 45 bpm with a regular rhythm. Every P wave is followed by a QRS complex, but the PR interval is prolonged at 0.28 seconds. What does this indicate?
Answer: First-Degree Atrioventricular (AV) Block
Explanation: A first-degree AV block is identified by a PR interval that exceeds 0.20 seconds. The rhythm remains regular, and there is still a one-to-one relationship between P waves and QRS complexes. This is generally considered a benign finding, but it should still be documented and monitored.
4. The monitor shows a heart rate of 180 bpm with a wide QRS complex. The rhythm is regular, and there are no visible P waves. What rhythm is this?
**Answer: Ventricular Tachycardia (VT)
Explanation: Ventricular tachycardia is a life-threatening dysrhythmia characterized by a heart rate typically above 150 bpm, wide QRS complexes (greater than 0.12 seconds), and a regular rhythm. The absence of P waves is a hallmark because the impulse originates in the ventricles, not the atria. This rhythm requires immediate intervention.
5. An ECG strip shows a heart rate of 60 bpm. The P waves are present but not conducted to the ventricles. There is no relationship between P waves and QRS complexes. What is this rhythm?
Answer: Third-Degree (Complete) Heart Block
Explanation: In third-degree heart block, the atria and ventricles beat independently. P waves and QRS complexes have no consistent relationship. The ventricular rate is typically slow and regular, often driven by an escape rhythm from the junctional or ventricular pacemaker It's one of those things that adds up. Still holds up..
6. A patient presents with a rhythm that is regular with a heart rate of 30 bpm. The QRS complexes are wide, and P waves are not identifiable. The patient is unresponsive. What is the most likely rhythm?
**Answer: Asystole
Explanation: Asystole is the absence of any electrical activity in the heart. On the monitor, this appears as a flat or nearly flat line. If the patient is unresponsive and without a pulse, asystole is a shockable or non-shockable cardiac arrest rhythm that requires immediate CPR and advanced life support.
7. A rhythm strip shows early beats occurring before the next expected QRS complex. These early beats have a narrow QRS and a P wave that looks different from the sinus P wave. What is this?
**Answer: Premature Atrial Complex (PAC)
Explanation: Premature atrial complexes originate from the atria before the next expected sinus beat. They often have a different morphology than the sinus P wave and are usually followed by a compensatory pause. PACs are common and usually benign.
8. A patient's rhythm is regular with a ventricular rate of 40 bpm. The P waves are visible but every second, third, or fourth P wave is not followed by a QRS complex. What does this suggest?
**Answer: Second-Degree AV Block, Mobitz Type II
Explanation: Mobitz Type II is characterized by a regular PP interval but intermittent non-conducted P waves. The key difference from Mobitz Type I is that the PR interval does not progressively lengthen. This type of block is more serious and can progress to complete heart block Easy to understand, harder to ignore..
How to Study Effectively for the Relias Dysrhythmia Basic A Test
Passing the Relias Dysrhythmia Basic A exam requires more than memorizing answers. You need to develop a strong understanding of cardiac physiology and rhythm interpretation. Here are some practical study tips:
- Practice with rhythm strips using websites like Practical Clinical Skills or ECG interpretation flashcards.
- Focus on the key features of each rhythm: regularity, heart rate, P wave morphology, PR interval, and QRS width.
- Learn the dangerous rhythms first — ventricular tachycardia, ventricular fibrillation, asystole, and PEA should be instantly recognizable.
- Use the 5-step method for rhythm analysis: rate, rhythm, P waves, PR interval, and QRS duration.
- Simulate test conditions by timing yourself and answering questions without looking at notes.
Frequently Asked Questions
Is the Relias Dysrhythmia Basic A test difficult?

What score do I need to pass?
The passing threshold is typically 80% or higher, though some organizations require 90%. Check with your facility
for exact expectations before testing.
Final Strategies for Test Day
Approach the exam systematically by reading each question carefully and eliminating obviously incorrect choices first. And pay close attention to keywords such as “regular,” “irregular,” “narrow,” or “wide,” as these guide you toward the correct rhythm category. When you encounter a rhythm strip, apply your 5-step method even under time pressure; consistency reduces careless errors. If you are unsure about a question, flag it and return later rather than losing momentum. Remember that the test is designed to measure competency, not perfection, so steady pacing and confidence in foundational concepts will serve you best Most people skip this — try not to..
Conclusion
Mastering basic dysrhythmia interpretation is both a skill and a habit that protects patients and strengthens clinical judgment. Still, trust your training, rely on proven frameworks, and recognize that each rhythm you learn adds another layer of safety to your practice. Because of that, by combining focused study, deliberate practice with rhythm strips, and a calm, methodical test-taking approach, you can meet and exceed the standards required for the Relias Dysrhythmia Basic A exam. With preparation and poise, you are well positioned to succeed.
