CRAT REVIEW EXAM Questions with
100% correct answers Latest Version
2024 GRADE A+
Transtelephonic Monitoring - answer-Transmitted over phone to a
LICENSED practitioner to read (magnetic tape), Patients use up to 30
days
Digital Monitoring - answer-Transmitted over a computer where
report is verified by a licensed practitioner
Telemedicine monitoring is usually used to evaluate_____________ -
answer-Artificial Pacemaker Functioning
Ambulatory Monitor - answer-Most common type is holter monitor
(continuous or intermittent-only records when patient has
symptoms. Used for dysrhythmias, evaluation cardic meds, and
checking pacemakers-24-48 hrs-up to 30 days
Procedure for applying ambulatory monitor (holter) - answer-Educate
patient, equipment gathered and prepared, electrodes placed on
chest, equipment hooked up
, Procedure for removing - answer-before removing, diary must be
complete by patient, then turn off recording, remove electrodes,
clean skin, report results
*process is based on type of equipment uses
Functions of common ECG machine - answer-3 basic functions are
input, signal processing, output display. Sensors in ECG machine
serve as receiving devices for the electrical activity of the heart.
INPUT-Electrode placed on patients skin direct impulses to ECG
instrument, providing the input. Signal processing happens in ECG
machine, output display is the result of processing and is shown on
screen (known as oscilloscope) and/or on ECG tracings. Electronic
output is quickly becoming most common choice for ECG tracings.
ECG machine controls - answer-# most common are speed, gain,
artifact filter.
also have these controls: LCD display, heart rate limits,
standardization, and lead section
Speed control - answer-regulates how fast or slow the paper or data
run during procedure. MOST COMMONLY USED: 25 mm/sec
*increasing the speed for example to 50mm/sec will make wave
forms appear wider and is useful if patient heart rate is very fast. if
you change the speed you must note on tracing by circling the setting
on tracing and notify the healthcare provider
*speed in measure on a horizontial axis
