EKG OPERATIONS 1

Which of the following describes how the EKG machine works

• records the electrical activity of the heart

• makes a picture of the heart

• makes a tracing of the heart and lungs activity

• records the impulse from the brain

in order to get a clear ekg tracing the patient must be lying:

• quietly in the prone position

• in the trandelendurg position

• in the sims position

• in supine position

which of the following describes the ekg electrode position

• it doesnt make any difference where the electrodes are placed on the patient, as long as each limb has a lead on it

• all electrodes must be placed in a specific location on the patients chest only

• the electrodes on the arms and legs are color coded and must be in the correct location. the chest electrodes must be in the correct location on patients chest

• all electrodes must be on the left chest wall

• 6

• 4

• 12

• 10

how many leads are recorded from the 6 chest electrodes

• 6

• 4

• 12

• 10

which of the following lubricants can be used when doing a 12 lead EKG

• paste with electrolytes in it

• paste without electrolytes in it

• ultrasound gel

• K-Y jelly

the EKG machine can pick up interference from which of the following sources

• other electrical machinery

• electrical wall outlets

• the patient

• all of the choices

which of the following leads are recorded strictly from the 4 extremities electrodes

• Lead 1, lead 2, lead 3

• AVR, AVL, AVF
