ANSWERS|100% VERIFIED|42 PAGES
The heart is made up of approximately how many cells?
200 hundred
One trillion
Half a billion
10 thousand - CORRECT ANSWERS-Approximately half a billion cells make up a
standard human heart. Most of them make up
the ventricular walls. There are approximately 100 million myocardial cells that contract
every
one third of a second.
If a patient is on continuous cardiac monitoring, which of the following leads would most
likely be seen on the monitor?
Lead III
Lead I
Lead II
All of the above - CORRECT ANSWERS-The typical lead that is displayed on a cardiac
monitor is lead II. Most cardiac monitor have the ability of changing this to a different
lead, but this has to be done by the healthcare staff.
Of the following rhythms, which would not be considered a life-threatening arrhythmia?
Ventricular fibrillation
Sinus rhythm with a 1st degree block
Asystole
Ventricular tachycardia - CORRECT ANSWERS-Some of the life-threatening rhythms
might include:
Ventricular fibrillation
Asystole
Ventricular tachycardia
Complete heart block
When checking the patient's orders prior to performing the ECG, the technician sees
that the patient's temperature is to be taken axillary. Which of the following routes would
be considered correct for axillary?
Ear
Mouth
Armpit
Anally - CORRECT ANSWERS-The ear would be considered tympanic.
The mouth would be considered orally.
,The anus would be considered rectally.
The armpit would be considered axillary.
Unresolved atrial fibrillation or atrial flutter is typically treated with which of the
following?
Lipitor
Coreg
Procardia
Coumadin - CORRECT ANSWERS-If atrial fibrillation or atrial flutter is unresolved, it
has the potential to developing blood clots. These patient's are typically placed on an
anticoagulant medication such as Coumadin.
The nurse is caring for a patient that has had a myocardial infarction and is
experiencing chest pain. Which of the following would be considered the typical
medication used for the relief of chest pain?
Coreg
Tylenol
Lidocaine
Morphine - CORRECT ANSWERS-Coreg, tylenol, and lidocaine is not used for
myocardial infarction chest pain. The drug of choice for most chest pain is considered
morphine. It is administered by IV per the dosage ordered by the physician. The typical
dose would be considered 2-5 mg and may repeat every 5 minutes up to 10 mg.
When the ECG technician is applying the electrodes for a stress test, they place the V1-
V6 leads and then which of the following?
RA/LA
aVL/aVF
RL/LL
Both A and C - CORRECT ANSWERS-With the stress test, there are 10 leads.
These leads include:
V1-V6
RA/LA
RL/LL
The mean instantaneous vector would be considered which of the following?
Bipolar lead
Unipolar lead
Electrical axis
Focal point - CORRECT ANSWERS-The mean instantaneous vector would be
considered the electrical axis. The electrical axis of the heart would be considered the
direction of the electromotive force that is developed in the heart during activation.
, Which of the following leads would help to record the electrical activity in the heart's
horizontal plane?
On a cardiac rhythm strip, which of the following can determine if the patients heart rate
is regular?
The RR intervals being equal.
The PP intervals being equal.
The RR intervals being unequal.
Both A and B - CORRECT ANSWERS-If the RR or PP intervals are not equal, then the
rhythm is irregular. One of the most uncommon rhythms
that is always unequal is atrial fibrillation.
If the physician orders a treatment for a patient that is supposed to help prevent
something from occurring, it would be considered which of the following
Prophylaxis
Chronic treatment
Acute treatment
None of the above - CORRECT ANSWERS-Chronic treatment would be over a length
of time.
Acute treatment would be for sudden diagnosis.
Prophylaxis would be treatment that would attempt to prevent something from occurring.
With a 12-lead electrocardiogram (ECG), which of the following would be the negative
electrode position for lead II?
Right arm
Left arm
Right leg
Left leg - CORRECT ANSWERS-The right arm would be the negative electrode position
for lead II. The left leg in lead II would be a positive electrode position. The right leg is
not included
in the lead I, II or III electrode positions.
If the sinus nodes fails to regulate the heart rhythm, it is considered which of the
following?
Septal defect
Idiopathic
SSS
Shunt - CORRECT ANSWERS-Septal defect is a hole in the heart wall that separates
the atria or the ventricles.
Idiopathic is no known cause.
Shunt is something that allows blood to flow between two locations.
SSS is sick sinus syndrome or when the sinus node fails (is sick) and cannot regulate
the hearts rhythm.
