When the technician is performing a 10
12 lead EKG, how many electrodes
are used to record the 12 views of When the technician is performing a 12 lead EKG,
the heart? 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 TB wave
would include all but which of the
following? Segments and waveforms on an ECG would
include:PR interval QRS complexQT intervalP
waveST segmentU waveT wave
The parasympathetic nervous system All of the above
would do which of the following?
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 Wandering baseline
conducting well or the placement is
wrong, which of the following could If the contact on a electrode is not conducting well
occur? 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 Determining the age of the patient
strip, all of the following would be
considered steps except? 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 0.20 seconds is the typical maximum length for PR
maximum length for a PR interval? interval. This of course can vary with heart rate
from 0.12 to 0.20 seconds.
Which of the following artifact results Electromagnetic interference, also known as 60
from electrical equipment, mobile cycle interference, is artifact caused by electrical
telephones, and electrical power equipment, mobile telephones, and electrical
lines? 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 Squares between two consecutive P waves
atrial rate, the technician should
count which of the following? 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 Providing financial counseling
considered a patient area of There are 4 areas of patient education:
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 NSAIDs
could cause bradycardia except? Bradycardia can be caused by the following
medications:
Beta-adrenergic blockers
Digoxin
Calcium channel blockers
Lithium
Antiarrhythmics (sotalol, amiodarone,
propafenone, and quinidine)
Generally, the chest leads are AV node
oriented through which of the
following to project through the The chest leads should be oriented through the AV
patient's back? node to project through the patient's back, which is
a negative charge to the leads positive charge. The
plane of the chest leads is called the horizontal
plane and it effectively separates the patient's
body into top and bottom halves.
