Which waveform on the ECG represents ventricular depolarization?
U wave
P wave
T wave
QRS complex
The QRS complex corresponds to ventricular depolarization. The P wave reflects atrial depolarization, the T wave ventricular repolarization, and the U wave late repolarization phenomena.
What is the normal duration of the PR interval on an ECG?
0.12 - 0.20 seconds
0.20 - 0.24 seconds
0.08 - 0.12 seconds
0.04 - 0.10 seconds
The PR interval normally ranges from 0.12 to 0.20 seconds, reflecting conduction from the sinoatrial node through the AV node. Intervals shorter or longer than this range indicate conduction abnormalities.
Before placing electrodes for telemetry monitoring, which action is most appropriate?
Clean and dry the skin at electrode sites
Apply alcohol-based hand sanitizer to the patient's hands
Shave the area five minutes before placement
Ask the patient to hold their breath
Cleaning and drying the skin reduces impedance and improves electrode contact. Alcohol-based products can leave residue, and shaving takes longer and may irritate; breath holding is not required.
A heart rate of 110 beats per minute on telemetry is termed:
Bradycardia
Asystole
Tachycardia
Arrhythmia
Tachycardia is defined as a heart rate above 100 beats per minute. Bradycardia is below 60, arrhythmia is any irregular rhythm, and asystole is absence of electrical activity.
How many electrodes are used in a standard five-lead telemetry system?
3 electrodes
12 electrodes
10 electrodes
5 electrodes
A five-lead telemetry system uses five electrodes to generate multiple lead views. A 12-lead ECG uses ten electrodes, and a three-lead uses three.
On an ECG strip, you observe no distinct P waves and an irregularly irregular rhythm. What arrhythmia is this?
Ventricular tachycardia
Atrial fibrillation
Atrial flutter
Sinus tachycardia
Atrial fibrillation is characterized by absent P waves and an irregularly irregular rhythm. Atrial flutter shows sawtooth waves, and the others have distinct P waves or regular QRS complexes.
A trending ST elevation across consecutive telemetry readings suggests which condition?
Early repolarization
Acute myocardial infarction
Myocardial ischemia
Pericarditis
ST-segment elevation that progresses over time is a hallmark of acute myocardial infarction. Ischemia often shows ST depression, while pericarditis has diffuse elevations and early repolarization is benign.
In a five-lead telemetry setup, where is the green electrode typically placed?
Left upper chest
Right upper chest
Right lower chest
Left lower chest
In standard five-lead systems, the green electrode is placed on the right lower chest. Other limb leads occupy the upper chest and opposite lower positions.
Which artifact is characterized by rapid, irregular baseline spikes due to muscle tremors?
Broken recording artifact
Wandering baseline
Muscle tremor artifact
AC interference
Muscle tremor artifact appears as rapid, irregular spikes caused by patient shivering or tremors. AC interference shows consistent sine-wave patterns, and wandering baseline drifts slowly.
A gradual 2 mm ST-segment depression trend over 30 minutes most likely indicates:
Acute pericardial effusion
Pulmonary embolism
Myocardial ischemia
Hyperkalemia
Progressive ST-segment depression suggests subendocardial ischemia. Pericardial effusion and pulmonary embolism have different ECG findings, and hyperkalemia shows peaked T waves.
Where is the V4 chest electrode placed during ECG lead placement?
Sixth intercostal space at anterior axillary line
Fifth intercostal space at midclavicular line
Second intercostal space at left sternal border
Fourth intercostal space at midaxillary line
V4 is positioned in the fifth intercostal space at the midclavicular line. Other positions correspond to different precordial leads.
A patient's telemetry alarm indicates SpO₂ has dropped to 85%. What should the nurse do first?
Change the telemetry module
Document the reading and continue monitoring
Assess the patient's airway and breathing
Replace the battery in the monitor
The first action is always to assess the patient's airway and breathing to correlate the reading with clinical status. Equipment checks follow patient assessment.
A PR interval consistently longer than 0.20 seconds indicates which condition?
First-degree AV block
Second-degree AV block
Third-degree AV block
Atrial fibrillation
A first-degree AV block is defined by a PR interval greater than 0.20 seconds. Higher-degree blocks show dropped beats or AV dissociation.
An ECG shows baseline wandering that varies slowly over several cycles. What is the most likely cause?
Loose electrode connection
Patient movement or respiration
Electromagnetic interference
Faulty lead wires
Baseline wandering that drifts slowly is typically caused by patient movement or deep respiration. Electromagnetic interference produces a regular 50 - 60 Hz pattern.
In lead V1, an rSR' pattern with a widened QRS complex indicates:
Atrial flutter
Ventricular tachycardia
Right bundle branch block
Left bundle branch block
An rSR' pattern in V1 with QRS duration over 120 ms is characteristic of right bundle branch block. Left bundle branch block has different morphology.
A telemetry strip displays a twisting morphology of the QRS complexes around the baseline. Which arrhythmia is this?
Atrial flutter
Ventricular fibrillation
Ventricular bigeminy
Torsades de Pointes
Torsades de Pointes is a polymorphic ventricular tachycardia with QRS complexes that appear to twist around the baseline. It is often associated with prolonged QT interval.
An ECG strip shows premature complexes with a noncompensatory pause, an early P wave, and a normal QRS complex. This describes:
Junctional rhythm
Atrial fibrillation
Premature atrial contraction
Premature ventricular contraction
Premature atrial contractions originate in the atria, producing an early P wave and normal QRS. The pause is noncompensatory, distinguishing it from ventricular ectopy.
The monitor alarm indicates asystole, but the patient is awake and talking. What is the most likely cause?
True asystole requiring CPR
Artifact from loose leads
Pulseless electrical activity
Ventricular fibrillation
If the patient is conscious but the monitor shows asystole, loose or disconnected leads are the probable cause. True asystole would render the patient unconscious.
To obtain posterior ECG leads V8 and V9, where should the electrodes be placed?
V8 at right sternal border, V9 at left anterior axillary line
V8 at left mid-scapular line, V9 at left paraspinal region
V8 at fourth intercostal space anterior, V9 at third intercostal space lateral
V8 at midclavicular fifth intercostal space, V9 at midaxillary sixth intercostal space
Posterior leads are placed on the back: V8 at the left mid-scapular line and V9 at the left paraspinal area. This view helps detect posterior infarction.
ST-segment elevations in leads II, III, and aVF are most indicative of an occlusion of which coronary artery?
Circumflex artery
Right coronary artery
Left main artery
Left anterior descending artery
Leads II, III, and aVF correspond to the inferior wall of the heart, typically supplied by the right coronary artery. Occlusion here produces an inferior MI pattern.
