MARKED A+
✔✔Which of the following might be considered the most common legal claim that could
be brought against a healthcare provider? - ✔✔Correct Answer:Negligence
The most common legal claim that could be brought against a healthcare provider
would be considered negligence. This would be considered to be correct for when a
person fails to use the degree of care that would be appropriate to the circumstances
that results in an unintended injury to another.
✔✔In regards to a temporary pacemaker, which of the following would not be
considered correct? - ✔✔Is implanted into the patient's chest
In regards to a temporary pacemaker, the following would be considered correct:
Is powered by an alkaline batteryIs connected to lead wires which are inserted into the
heart of the patientIs a small exterior box
A temporary pacemaker is typically placed during an emergency. This is a small exterior
box which is powered by alkaline batteries. The lead wires are placed into the heart of
the patient or can potentially be used with electrode pads that are placed on the
patient's chest (sometimes not as effective).
✔✔Which of the following houses a battery, electronic circuitry for pacemaker settings,
and a lead connector? - ✔✔Pulse generator
The pulse generator is part of the pacemaker system that houses a battery, electronic
circuitry for pacemaker settings, and a lead connector. The other part of a pacemaker
system is the pacing lead.

✔✔From the start of the QRS to the finishing of the T wave would be considered which
of the following? - ✔✔QT interval
From the start of the QRS to the finishing of the T wave would be considered the QT
interval. The measurement would start where the Q wave first starts and then is finished
when the T wave stops. This represents the ventricular activity.
✔✔On the rhythm strip, if there is a early beat showing randomly but most of the strip
shows normal sinus rhythm, it is called which of the following? - ✔✔PJC
On the rhythm strip if there is a early beat showing randomly but most of the strip shows
normal sinus rhythm, it is called premature junctional contraction (PJC). This starts in
the AV junction which is what normally acts as the pacemaker for the heart.
✔✔Of the following, which supplies the most blood to the SA node? - ✔✔Right coronary
arteries
, The right coronary arteries supply approximately 60-70% of the blood to the SA node.
The SA node is supplied blood by the SA node artery which is supplied blood by the
following coronary arteries:
The right coronary arteries (approximately 60-70%)
The left circumflex arteries (approximately 20-30%)
✔✔Of the following, which would be considered the most serious of the heart blocks? -
✔✔Third degree
The third degree heart block (complete heart block) would be considered the most
serious of all the heart blocks. It can be considered life threatening and can lead to
cardiac arrest if not treated immediately.
✔✔ When the technician is performing a 12 lead EKG, how many electrodes are used
to record the 12 views of the heart? - ✔✔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? -
✔✔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? - ✔✔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? - ✔✔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? - ✔✔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.
