ELECTROCARDIOGRAM (ECG)

What does the P wave represents?

• Depolarization of atria

• Repolarization of ventricles

• Depolarization of ventricles

• Depolarization of atria and ventricles

Which of the following indicates Ventricular Depolarization?

• P Wave

• PR Interval

• QRS Complex

• T Wave

Types of ECG rhythm.

• Ventricular Fibrillation

• Sinus Bradycardia

• Atrial Flutter

• Atrial Fibrillation

The classic ECG changes in Myocardial Infarction are

• T-Wave inversion

• ST-segment elevation

• Development of an abnormal Q wave

• All of the answers

An ECG can help detect problems, EXCEPT:

• Arrhythmias

• Coronary heart disease

• Heart attacks

• Deep Vein Thrombosis (DVT)

Which one is Second Degree Block Type 1 (Wenckebach)?

• 
• 
• 
• 

Which part of the PQRST complex represent atrial depolarization?

• P Wave

• QRS Complex

• T Wave

• ST - Segment

When a heart muscle cell goes back into its negatively charged state or when it relaxes is known as?

• Polarization

• Depolarization

• Repolarization

The nurse is caring for a client who is displaying a third-degree AV block on the ECG monitor. What is the priority nursing intervention for the client?

• assessing blood pressure and heart rate frequently

• identifying a code-level status

  heart block

• maintaining intravenous fluids

• alerting the doctor of the third-degree

Why does ECG uses 10 electrode and not 12 electrode since its called 12 Leads ECG?

• The 10 electrodes more accurate than 12 lead ECG

• The 10 electrodes placement can obtain and read 12 different angles.

• 10 electrodes provides 12 perspective of heart activities through 2 planes : ventricles & horizontals.

• 10 eletrode provides 12 views of readings.
