• Clean shaven

• Wet Skin

In which of the following situations could the condition of the patient's skin can interfere with electrode contact?

• Soiled skin

• Dry Skin

• Body Hair

• Dark Colored Skin

What type of baseline interference is caused by electrodes that have dried out?

Artifact

• Something that happens when you are obtaining an EKG on a patient that you cannot control, fix, or alter.

• An object made of a number of raw materials, the most common of which are: chipped stone, ground stone, clay, bone, shell, wood, fibers, and metal

• Any interference with the recording of the EKG - may be environmental factors, defective equipment, or patient conditions

• An object made by a human being, typically an item of cultural or historical interest

Which of the following would be considered an environmental factor that could create a Wandering baseline form of artifact on an EKG? (Select ALL that apply)

• An EKG machine that has a faulty ground wire

• Movement of muscle groups - such as during breathing

• Loose electrodes

• Electrode gel is dried out

• Tremors or shivering

Which of the following would be considered an environmental factor that could create a Somatic Tremor form of artifact on an EKG? (Select ALL that apply)

• Tremors or shivering

• An EKG machine that has a faulty ground wire

• Movement of muscle groups - such as during breathing

• Patient is anxious

• Electrical appliances in close proximity to the EKG machine

Which of the following would be considered an environmental factor that could create an Electrical interference form of artifact on an EKG? (Select ALL that apply)

• Loose electrodes

• Electrode gel is dried out

• Fluorescent lights

• An EKG machine that has a faulty ground wire

• Electrical appliances in close proximity to the EKG machine

Which of the following would be considered an environmental factor that could create a Broken recording form of artifact on an EKG? (Select ALL that apply)

• An EKG machine that has a faulty ground wire

• Loose electrodes

• Frayed or broken lead wires

• Electrode gel is dried out

• Patient is anxious

Why should an EKG technician avoid placing electrodes on surgical scars or open wounds?

• It doesn't really matter, you HAVE to place them in the correct anatomical position to get a good EKG

• The skin may be fragile and may be injured when the electrode is removed from the skin

• The scar will cause an increase in the size of the EKG tracing

• The wound will increase the size of the EKG tracing

Why should patients who are in their last trimester of pregnancy never be placed flat on their backs?

• Because it will make the baby sick and therefore mom sick

• Because it will make mom have to pee

• Because the baby can put pressure on the Vena Cava and ultimately reduce blood flow and oxygen flow to the baby

• Because it will cause the baby to grow faster
