Medical-Surgical Telemetry B Exam 2025/2026 Dysrhythmia Interpretation (25 Questions) Question 1 An EKG strip shows a heart rate of 120 bpm with irregular R-R intervals and no discernible P waves. What is the rhythm?

• Sinus tachycardia
• Atrial fibrillation
• Ventricular tachycardia
• Second-degree AV block

Rationale: Atrial fibrillation is characterized by irregular R-R intervals and absent P waves due to chaotic atrial activity, per ACLS guidelines. 1 / 3

Question 2 A patient with ventricular tachycardia becomes pulseless. What is the first action?

• Administer amiodarone
• Initiate CPR
• Deliver synchronized cardioversion
• Administer epinephrine

Rationale: Pulseless ventricular tachycardia requires immediate CPR to restore circulation, per ACLS algorithms.Question 3 An EKG shows a prolonged PR interval (0.24 seconds). What is the rhythm?

• Normal sinus rhythm
• First-degree AV block
• Second-degree Mobitz I
• Third-degree AV block

Rationale: A PR interval >0.20 seconds indicates first-degree AV block, per EKG interpretation standards.Question 4 A patient’s EKG shows wide QRS complexes at 150 bpm with no P waves. What is the priority action?

• Administer adenosine
• Prepare for synchronized cardioversion
• Administer beta-blockers
• Monitor the patient

Rationale: Wide QRS tachycardia suggests ventricular tachycardia, requiring synchronized cardioversion if stable, per ACLS protocols.Question 5 Which EKG finding indicates hyperkalemia?

• Flat T waves
• Peaked T waves
• Prolonged QT interval
• ST depression 2 / 3

Rationale: Peaked T waves are a hallmark of hyperkalemia due to altered cardiac

repolarization, per critical care guidelines.Question 6 A patient’s EKG shows sinus bradycardia at 40 bpm with dizziness. What is the first action?

• Administer epinephrine
• Administer atropine
• Prepare for cardioversion
• Increase IV fluids

Rationale: Symptomatic bradycardia requires atropine as the first-line treatment, per ACLS guidelines.Question 7 An EKG strip shows frequent premature ventricular contractions (PVCs). What should you assess?

• Blood glucose
• Electrolyte levels
• Respiratory rate
• Temperature

Rationale: PVCs may be caused by electrolyte imbalances (e.g., hypokalemia), requiring assessment, per telemetry standards.Question 8 A patient’s EKG shows a regular rhythm with a rate of 180 bpm and narrow QRS complexes.What is the likely rhythm?

• Ventricular tachycardia
• Supraventricular tachycardia
• Atrial flutter
• Sinus rhythm

Rationale: Narrow QRS tachycardia at a high rate suggests supraventricular tachycardia, per EKG interpretation guidelines.Question 9 What is the first action for a patient with atrial flutter and a heart rate of 150 bpm?

• Administer amiodarone
