EXAM PAPER 2026 QUESTIONS SOLUTIONS
GRADED A+
◉ 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
,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
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
