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?
A. Sinus tachycardia
B. Atrial fibrillation
C. Ventricular tachycardia
D. 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.
,Question 2
A patient with ventricular tachycardia becomes pulseless. What is the first action?
A. Administer amiodarone
B. Initiate CPR
C. Deliver synchronized cardioversion
D. 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?
A. Normal sinus rhythm
B. First-degree AV block
C. Second-degree Mobitz I
D. 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?
A. Administer adenosine
B. Prepare for synchronized cardioversion
C. Administer beta-blockers
D. 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?
A. Flat T waves
B. Peaked T waves
C. Prolonged QT interval
D. ST depression
, 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?
A. Administer epinephrine
B. Administer atropine
C. Prepare for cardioversion
D. 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?
A. Blood glucose
B. Electrolyte levels
C. Respiratory rate
D. 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?
A. Ventricular tachycardia
B. Supraventricular tachycardia
C. Atrial flutter
D. 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?
A. Administer amiodarone
