CCMA REVIEW MODULE 13

which is represented by a flatline on an ekg strip

on a standard 12 lead EKG, how many electodes are placed on the body?

a ma is performing an ekg and notices the heartrate to be 105. the ma should identify this finding as what

a ma is providing teaching to a patient who is to undergo holter monitring. which should the ma include

when performing an ekg a ma notices a wide qrs complex, which is a possible cause

an ma is providing instructions for a patient who is having a stress test the next day, which is correct

left of the chest, 5th intercostal space, midaxillary line

characterized by irregular spikes on the tracing due to muscle movement

only electode on the RIGHT side of the chest, 4th intercostal space

an ma is preparing a patient who is short of breath for an ekg, what postion should the patient be placed in

if p waves are absent it may be necessary to change the standard speed of 25 mm/sec to what speed?

left of the chest, fifth intercostal space, anterior axillary line

what is the ratio for applied leads to recorded leads for a standard ekg machine

what instructions should the ma provide

what might cause external artifact on an EKG

a normal ekg with a heart rate greater than 100

which is the correct sequence for placing the precordial electrodes on the chest

a multichannel EKG machine is a recorder that monitors how many leads?

this results from poor connection, usually from olis, lotions or hair on the chest

left side of the sternum, directly across from v1 - fourth intercostal space

the standardized speed for the ekg machine should be set at a rate of what?

unwanted external interference occuring in an EKG tracing

represents ventricular depolarization or contraction on the ekg

what represents atrial depolarization or contraction on the ekg

the MA realizes the limb leads were placed incorrectly after the ekg tracing, what should the ma do?

left of the chest, 5th intercostal space, midclavicular line

a medical assistant is calibrating the ekg machine. what standard speed should the machine be set at

when the heart stops and no rhythm is detected

in atrial fibrillation there is no organized rhythm, only quivering, we should be worried about what in this state

which leads on an EKG are considered bipolar?

this occurs when there is an electical interference such as a cell phone, computer or crossed lead wires

what represents ventricular repolarization on an ekg

normal ekg tracing with a heart rate of less than 60 bpm

V1-V6 area ll precordial leads, what does this mean?

this occurs when there is a break in the lead wire or a disconnection
