CCT EXAM SOLVED QUESTIONS AND VERIFIED
SOLUTIONS
◉ Of the electrocardiogram waves, which would be considered the
first deflection after the diastole that is produced because of the
atrial depolarization?
-T wave
-S wave
-Q wave
-P wave.
Answer: P wave
This occurs because of the atrial depolarization of the heart.
◉ The Bundle of His has an intrinsic firing rate of which of the
following?
-40 to 60 beats per minute
-30 to 60 beats per minute
-60 to 80 beats per minute
-80 to 100 beats per minute.
,Answer: 40-60 beats per minute
The Bundle of His is located at the superior portion of the
interventricular septum. The Bundle of His is actually the pathway of
the electrical impulses that lead out of the SA node.
◉ If a patient is experiencing a low blood pressure, which of the
following terms would be correct?
-Hyper tension
-Hypoxemia
-Hypotension
-Hypoplastic.
Answer: Hypotension
Hypertension: high blood pressure
Hypoxemia: low oxygen concentration in the blood
Hypoplastic: when an organ is abnormally small because of a
problem with development prior to birth
Hypotension: low blood pressure
◉ The aVR lead picks up electrical activity from which of the
following?
,-The center of the heart to the right arm
-The center of the heart to the left leg
-The center of the heart to the left arm
-From the left arm to the left leg.
Answer: The center of the heart to the right arm
The center of the heart to the left leg: aVF
The center of the heart to the left arm: aVL
The center of the heart to the right arm: aVR
From the left arm to the left leg: lead III
◉ The Q wave should have a duration of less than how many
seconds?
-0.30 seconds
-0.20 seconds
-0.10 seconds
-0.04 seconds.
Answer: 0.04 seconds
, The Q wave should have a duration of less than 0.04 seconds. It is
the first negative component of the QRS complex and if it lengthens,
it could be indicative of a myocardial infarction
◉ When the mitral valve opens, the blood flows from the left atrium
to which of the following?
-The right atrium
-The left ventricle
-The right ventricle
-The lungs.
Answer: The left ventricle
◉ Which of the following age groups would be most likely to
experience fibrosis in the conduction system?
-21-30 years of age
-Infants
-The elderly
-40-60 years of age.
Answer: The elderly
