ECG Chapter 4

Name three types of isolation precautions and describe the ppe required for each

Airborne precautions Droplet precautions Contact precautions

Why do you need to frequently adjust the paper to 50 mm/sec for infants and small children

Because the readings

What must be done before you run the actual ecg tracing

Communication with patient Prep room and patient Provide privacy Provide safety and infection control Located and checked equipment Loaded ecg paper

Cause of artifact

Could be broken lead wires

What should you remember when asked to record a right side or posterior ecg

Is a straight line

Name three causes of wandering baseline

Loose lead wires

Name at least three things you can do to ensure safety during an ecg

Never leave side rail un attended make sure they are laying down Check that grounding prong is secure

What is the difference between continuous cardiac monitoring and a routine ecg

One is 12-lead

2

Paraspinonal line

Describe how you run the ecg machine to create lead tracing

Should be set between t wave and p wave

How can you be certain you are attaching the lead wires to the electrodes properly

The wire to the electrode properly should avoid looping the wires outside of the body and check each wires once it connected to ensure that there is no tension on the lead electrodes or leads.

Why should you place the limb electrodes before the chest electrodes

To avoid looping

Why should you know how to troubleshoot and maintain the equipment for an ecg

To get proper data

fifth intercostal space at the midclavicular

V4

2

You change the speed when you have a child or infant because of there different readings

you notices a wondering baseline on the ECG tracing. What measure (s) should you do to correct?

apply new electrodes

when applying chest leads, V2 is placed

at the fourth ICS, left sternal border

What should you do if a patient refuses an ECG?

determine the cause of the refusal some people may have fear or concern about the procedure provide any info or reassurance the patient may need

V3

halfway between V2 and V4

What should you indicate to the patient when closing the door or pulling the curtain before performing an ECG?

inform them that closing the door or curtain is for their privacy

For placement of the electrodes, how is the ICS located?

locating the sternum and feeling for a dip at the edge

Where is the angle of Louis?

main part of the sternum and the manubrium attach

Which anatomical landmark starts in the middle of the axilla and runs down the side of the chest?

midaxillary line

What information must be included on the ECG requisition?

patient name ID # DOB location date time patient age sex race cardiac or other medications patient is currently taking weight height any special condition or position of patient during recording

Name four important aspects of preparing for the ECG procedure.

prepare the room, order form must be completed prior to the procedure, identifying information should be entered through the LCD panel on the ECG machine prior to the reading, make sure the machine has a good supply of paper loaded in it

when the tracing of an ECG drifts away from the center of the paper; also called baseline shift (it was many causes, which can be corrected)

wandering baseline

To prevent disease transmission during an ECG you should

wash your hands
