CCI CRAT Exam Practice Test 2 with
correct answers 2024
When the technician is performing a 12 lead EKG, how many
electrodes are used to record the 12 views of the heart? - answer-
10
When the technician is performing a 12 lead EKG, there would be
10 electrodes used to record the 12 leads or views of the heart.
Twelve leads doesn't necessarily mean 12 electrodes.
Segments and waveforms on an ECG would include all but which of
the following? - answer-TB wave
Segments and waveforms on an ECG would include:PR interval QRS
complexQT intervalP waveST segmentU waveT wave
The parasympathetic nervous system would do which of the
following? - answer-All of the above
The parasympathetic nervous system would:Slow the patient's
heart rateEnhance digestionDecrease the patient's blood pressureIs
mediated by acetylcholine
If the contact on a electrode is not conducting well or the
placement is wrong, which of the following could occur? - answer-
Wandering baseline
,CCI CRAT Exam Practice Test 2 with
correct answers 2024
If the contact on a electrode is not conducting well or the
placement is wrong, it could cause a wandering baseline. The
wandering baseline can also be caused by chest wall during
respiration.
When interpreting a cardiac rhythm strip, all of the following would
be considered steps except? - answer-Determining the age of the
patient
When interpreting a cardiac rhythm strip, there are 5 steps:
Examine all of the components and the shape of the waveforms.
Check the position of the P wave.
Determine if all the complexes are alike.
Determine the rate of the rhythm and if it is normal or abnormal.
Evaluate if the rhythm is regular or irregular.
Which of the following is the typical maximum length for a PR
interval? - answer-0.20 seconds is the typical maximum length for
PR interval. This of course can vary with heart rate from 0.12 to 0.20
seconds.
Which of the following artifact results from electrical equipment,
mobile telephones, and electrical power lines? - answer-
Electromagnetic interference, also known as 60 cycle interference,
is artifact caused by electrical equipment, mobile telephones, and
, CCI CRAT Exam Practice Test 2 with
correct answers 2024
electrical power lines. To minimize 60 cycle interference (or 60 Hz
pickup), the technician should set the diagnostic mode of the 12-
lead electrocardiogram monitor to 0.05-40 Hz. With the low
frequency/high pass filter set to 0.05 the monitor should produce
accurate ST-segments.
In the 1,500 method for calculating atrial rate, the technician should
count which of the following? - answer-Squares between two
consecutive P waves
To calculate atrial rate with the 1,500 method, the technician would
tally the little squares between two consecutive P waves and then
divide 1,500 by that amount. There are 1,500 small squares in a one
minute rhythm strip.
Which of the following would not be considered a patient area of
education? - answer-Providing financial counseling
There are 4 areas of patient education:
1.Restoration of health
2.Maintenance and promotion
3.Coping with new illness or impairment
4.Prevention of illness and injury
All of the following medications could cause bradycardia except? -
answer-NSAIDs
