❖ Spring Semester 2026 – RELIAS Medical-Surgical Telemetry Exam
Comprehensive Study Guide | Practice Questions with Verified
Answers and Detailed Rationales | Cardiac Monitoring, Arrhythmia
Interpretation, Patient Assessment, Nursing Interventions,
Electrolyte Management, and Critical Care Applications
Question 1:
What is the primary purpose of telemetry monitoring in a medical-surgical setting?
A) To provide direct patient care
B) To continuously monitor vital signs and cardiac rhythms
C) To administer medications
D) To assist in surgical procedures
Correct Answer: B) To continuously monitor vital signs and cardiac rhythms
Rationale:
Telemetry monitoring allows healthcare professionals to continuously observe a
patient's vital signs, especially cardiac rhythms. This is crucial for early detection of
abnormalities, timely interventions, and improving patient outcomes, especially in high-
risk medical-surgical settings.
Question 2:
Which of the following arrhythmias is most commonly associated with Myocardial
Infarction (MI)?
A) Atrial Fibrillation
B) Ventricular Tachycardia
C) Sinus Bradycardia
D) Ventricular Fibrillation
Correct Answer: D) Ventricular Fibrillation
Rationale:
Ventricular fibrillation is a life-threatening arrhythmia often associated with myocardial
infarction. It results from abnormalities in the electrical conduction system of the heart,
leading to ineffective contractions and can quickly result in cardiac arrest without
immediate intervention.
Question 3:
When assessing a telemetry strip, which characteristic indicates the presence of a P
wave?
A) A narrow spike preceding the QRS complex
B) A broad, irregular waveform
,C) A flat line between the QRS complex
D) A prominent S wave
Correct Answer: A) A narrow spike preceding the QRS complex
Rationale:
A P wave represents atrial depolarization and typically appears as a small, upright wave
preceding the QRS complex on a telemetry strip. Its presence is essential for assessing
the normal functioning of the heart's conductive system, indicating effective atrial
contraction and rhythm.
Question 4:
What intervention should a nurse prioritize for a patient experiencing symptomatic
bradycardia?
A) Administering antihypertensive medication
B) Starting cardiopulmonary resuscitation (CPR)
C) Administering Atropine
D) Restricting fluid intake
Correct Answer: C) Administering Atropine
Rationale:
Atropine is indicated for treating symptomatic bradycardia as it increases heart rate by
blocking the vagus nerve's effects. Timely administration is crucial in preventing
complications related to inadequate heart rate, such as decreased cardiac output and
potential syncope.
Question 5:
In a telemetry unit, abnormal heart sounds detected during auscultation may indicate
which condition?
A) Heart failure
B) Asthma
C) Gastroesophageal reflux disease
D) Stroke
Correct Answer: A) Heart failure
Rationale:
Abnormal heart sounds, such as S3 and S4, can indicate heart failure, reflecting volume
overload and impaired myocardial function. Recognizing these sounds is essential in
telemetry monitoring, as they provide insight into the patient’s hemodynamic status and
guide further assessment and intervention.
,Question 6:
What is the most common rhythm seen in patients with chronic obstructive pulmonary
disease (COPD)?
A) Sinus Tachycardia
B) Atrial Fibrillation
C) Sinus Bradycardia
D) Ventricular Fibrillation
Correct Answer: B) Atrial Fibrillation
Rationale:
Atrial fibrillation is frequently observed in patients with COPD due to the associated
hypoxia and increased pulmonary pressure, leading to structural changes in the heart.
Early recognition and management are vital to prevent complications.
Question 7:
Which electrolyte disturbance is most likely to cause life-threatening arrhythmias?
A) Hypercalcemia
B) Hyperkalemia
C) Hyponatremia
D) Hypermagnesemia
Correct Answer: B) Hyperkalemia
Rationale:
Hyperkalemia can lead to significant cardiac changes, including peaked T-waves, QRS
widening, and even ventricular fibrillation. Monitoring potassium levels is crucial in
patients receiving certain medications, such as ACE inhibitors.
Question 8:
What is the primary strategy for managing a patient with supraventricular tachycardia
(SVT)?
A) Immediate defibrillation
B) Vagal maneuvers
C) Administration of sedatives
D) Cardioversion
Correct Answer: B) Vagal maneuvers
Rationale:
Vagal maneuvers, such as the Valsalva maneuver, can help to slow heart rate and
, restore normal sinus rhythm in cases of SVT. These are often effective and non-invasive
treatments prior to pharmacological interventions.
Question 9:
In the context of telemetry, which of the following is a major concern with the use of
antipsychotic medications?
A) Acute kidney injury
B) Cardiac arrhythmias
C) Gastrointestinal bleeding
D) Respiratory depression
Correct Answer: B) Cardiac arrhythmias
Rationale:
Antipsychotic medications are associated with an increased risk of QT prolongation,
leading to potentially dangerous arrhythmias like Torsades de Pointes. Continuous
telemetry monitoring is vital in patients on these medications.
Question 10:
What does a prolonged QRS complex indicate?
A) Atrial enlargement
B) Ventricular hypertrophy
C) Delay in ventricular conduction
D) Normal variation
Correct Answer: C) Delay in ventricular conduction
Rationale:
A prolonged QRS complex suggests a delay in the conduction system within the
ventricles, commonly due to bundle branch block or other conduction abnormalities.
Identifying this can impact treatment decisions.
Question 11:
What is the essential nursing action when a telemetry alarm sounds?
A) Notify the physician immediately
B) Assess the patient and check the lead placement
C) Silence the alarm
D) Document the alarm without assessment
Correct Answer: B) Assess the patient and check the lead placement
