When the technician is performing a 12 lead EKG, how many electrodes are used to record the 12 views of the heart? - correct 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? - correct 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? - correct 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? - correct answer Wandering baseline
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? - correct 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? - correct 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? - correct answer Electromagnetic interference, also known as 60 cycle interference, is artifact caused by electrical equipment, mobile telephones, and 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? - correct 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? - correct 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? - correct answer NSAIDs
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 oriented through which of the following to project through the patient's back? - correct answer AV node
The chest leads should be oriented through the AV 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.
When setting up limb leads and placing them in equal distances from the heart, it is typically known as which of the following? - correct answer Einthoven's triangle
When setting up limb leads and placing them in equal distances from the heart, it is typically known at Einthoven's triangle. The leads will form a equilateral triangle with the right arm electrode being negative.
