Exam 4: Technical Aspects of the EKG

Sixty-cycle interference is commonly caused by

If there is artifact in leads II,III,and aVF,on which limb(s)would you expect to find the cause of the artifact?

Normal paper speed for printing out the EKG is

If artifact is seen in leads I,III,and aVL,you should direct your corrective efforts to which limb or limbs?

Using an EKG machine with frayed wires is not dangerous if the wires are taped together.

Electrically speaking,the EKG machine is a ________ and the heart is a transmitter.

The part of the EKG machine that converts an analog signal to a digital signal is the

CPR artifact is seen only during CPR.

Which of the following correctly describes the function of the gain setting on the EKG machine?

Troubleshooting involves determining and alleviating the cause of ________.

Muscle artifact can be minimized by monitoring the patient in Lead

A digital converter on the EKG machine

Macroshock and microshock are two kinds of electrical shock the patient can sustain from faulty equipment.

A thick-looking pattern on the EKG paper that looks like someone used a thick Magic Marker to write the baseline is typical of what kind of artifact?

Artifact does not cause symptoms of decreased cardiac output.

If your patient's cardiac rhythm is life-threatening,your FIRST action should be to

If you think the rhythm is artifact,check your patient for any symptoms of decreased cardiac output first,then check his monitor wires and patches and observe the rhythm in another lead.

"Toothbrush tachycardia" can be lethal.

Microshock is different from macroshock in that microshock is

Your patient is smiling and visiting with family,but the cardiac monitor shows that the patient's heart has completely stopped.The rhythm on the monitor is thus
