Chapter 1 EKG Exam

What do the letters EKG stand for?

• Electrocardiograph
• Electromagneticgraph
• Electrocardiogram 
• Electrolytes

An electrocardiogram measures what?

• The amount of pressure exerted on blood vessels.
• The electrical activity of the heart.
• How many times the heart contracts over time.
• The body's temperature caused by friction of blood in vessel.

What letters are used to label the parts of an EKG?

• PQRST 
• ABCDE
• ACDC
• DNAI

Which of the following is not a direct indicator of a person's cardiac health?

• Heart Rate
• Blood Pressure
• EKG
• Temperature 

The p-wave correlates with which event?

• atrium contraction /signals moving from SA node to AV node
• ventricle contraction
• ventricle repolarization
• both atrial and ventricle contraction

The place where the electrical current starts and is considered the heart's pacemaker:

• Sino-atrial node 
• right atrium
• atria-ventricular node 
• left ventricle

The AV node is located at...

• A
• B
• C
• D

The nurse is assessing the client’s electrocardiography (ECG). What does the P wave on the ECG tracing represent?

• Contraction of the atria

• Contraction of the ventricles

• Depolarization of the atria

• Depolarization of the ventricles

The nurse is reviewing a patient’s electrocardiogram. Which wave should the nurse recognize as being the first positive wave in a normal cardiac cycle?

• P wave

• Q wave

• R wave

• S wave

After reviewing an electrocardiogram the nurse determines that an electrical impulse originated in a patient’s the sinoatrial node. What did the nurse see on this tracing?

• An upright T wave

• An inverted T wave

• A positive P wave before a QRS complex

• A negative P wave before a QRS complex
