With ventricular fibrillation, the waves would be considered
which of the following?
-Fibrillation waves
-Chaotic waves
-Saw-tooth waves
-None of the above correct answer: Chaotic waves
With ventricular fibrillation, the waves may be fine or coarse.
With ventricular fibrillation, the waves are considered chaotic
waves
Of the following conditions, which would be appropriate for the
use of an AED?
-The patient is pulseless
-The patient is unresponsive
-The patient is not breathing effectively
-All of the above correct answer: All of the above
Some of the circumstances that an AED should be used:
The patient is pulseless
The patient is unresponsive
The patient is not breathing effectively
The patient is having chest pain
Which of the following would cause an irregular rhythm?
-P waves
-ST segment
-PR interval
-Premature complexes correct answer: Premature complexes
Most irregular rhythms are caused by premature complexes.One
of the most common irregular rhythms would be considered
atrial fibrillation
Which of the following would be considered correct for the
main vital signs that are routinely monitored by the ECG
technician during an ECG\/stress test?
-Blood pressure
-Pain level
-Pulse oximetry
-Weight correct answer: Blood pressure
The main vital signs that are routinely monitored would include:
Blood pressure
Heart rate
EKG
Of the following, which would be considered the correct term
for when the heart is located within the right side of the chest?
-Encephalopathy
-Dextrocardia
-Representation
-All of the above correct answer: Dextrocardia
Dextrocardia would be considered the most common form of
malposition of the heart. With dextrocardia, the heart is actually
located on the right side of the chest rather than the left side of
the heart. This condition is to be suspected when there is a
negative P wave and QRS in lead 1. The technician should
always check first to be sure that there has not been a technical
error such as the left and right arm leads being reversed
Which of the following would be considered the most important
factor in using a set system for the interpretation of cardiac
rhythm strips?
-To make job easier
-To help prevent the technician from overlooking potentially
important findings
-To give the technician something to do
-None of the above correct answer: Prevent the technician from
overlooking potentially important findings
There are a few different systems that can be used for
interpreting ECG strips. The clinician needs to find the one that
works the best for them. In addition to the above, other benefits
can include an increase in the accuracy, an increase in the speed
of their interpretation, and better organization
Which of the following would best describe an AED (automated
external defibrillator)?
-A cardioverter defibrillator that is implanted
-An external piece of equipment that can be used to provide an
electrical shock that could restore a person’s heart to a normal
rhythm
-An echocardiogram
-None of the above correct answer: An external piece of
equipment that can be used to provide an electrical shock that
could restore a person’s heart to a normal rhythm
An AED is a non-invasive external piece of equipment that can
be used to provide an electrical shock that could restore a
person’s heart to a normal rhythm. Most businesses today
provide an AED and train staff as to the use of it to help save
workers in case of an emergency
When assessing the patient that is experiencing chest pain,
which of the following life-threatening diagnosis might be
considered?
-Dissecting aortic aneurysm
-Pulmonary embolus
-Both A and B
-None of the above correct answer: Both A and B
Some of these life-threatening diagnosis includes:
Dissecting aortic aneurysm
Pulmonary embolus
Angina pectoris
Myocardial infarction
The aortic valve is between?
-Right ventricle and the left ventricle
-Aorta and the left ventricle
-Left ventricle and the pulmonary trunk
-Left atrium and the pulmonary trunk correct answer: Aorta and
the left ventricle
Of the following, which would be considered the best
description for the term “complex” with an electrocardiogram?
-The complex consist of 5 waveforms<\/p>\n","protected":false},"excerpt":{"rendered":"
