DETAILED SOLUTIONS
Question: With a 12-lead electrocardiogram (ECG), which of the following would be the
negative electrode position for lead II?
Right arm
Left arm
Right leg
Left leg - CORRECT ANSWER✔✔The right arm would be the negative electrode position for lead
II. The left leg in lead II would be a positive electrode position. The right leg is not included
in the lead I, II or III electrode positions.
Question: If the sinus nodes fails to regulate the heart rhythm, it is considered which of the
following?

Septal defect
Idiopathic
SSS
Shunt - CORRECT ANSWER✔✔Septal defect is a hole in the heart wall that separates the atria or
the ventricles.
Idiopathic is no known cause.
Shunt is something that allows blood to flow between two locations.
SSS is sick sinus syndrome or when the sinus node fails (is sick) and cannot regulate the hearts
rhythm.
Question: The positive electrode in lead II is placed in which position on the patient?
Right chest area

Question: The heart is made up of approximately how many cells?
200 hundred
One trillion
Half a billion
10 thousand - CORRECT ANSWER✔✔Approximately half a billion cells make up a standard
human heart. Most of them make up
the ventricular walls. There are approximately 100 million myocardial cells that contract every
one third of a second.
Question: If a patient is on continuous cardiac monitoring, which of the following leads would
most likely be seen on the monitor?
Lead III
Lead I
, Page 4 of 151
Lead II
All of the above - CORRECT ANSWER✔✔The typical lead that is displayed on a cardiac monitor is
lead II. Most cardiac monitor have the ability of changing this to a different lead, but this has to
be done by the healthcare staff.
Question: Of the following rhythms, which would not be considered a life-threatening
arrhythmia?
Ventricular fibrillation
Sinus rhythm with a 1st degree block
Asystole
Ventricular tachycardia - CORRECT ANSWER✔✔Some of the life-threatening rhythms might
include:
Ventricular fibrillation
Asystole
Ventricular tachycardia
Complete heart block
