Print out a representation of the heart's mechanical functioning.
Print out a representation of the heart's electrical current.
Augment the heart's current when there is none.
What feature do some modern EKG machines have?
Able to run the EKG without electrodes and wires
Capable of defibrillating patients
Bluetooth capable
Able to tell the paramedic what medication to give
When is it most useful to adjust the speed on the EKG machine?
When the patient's rhythm is rapid
When the physician needs the tracing quickly
When the patient's rhythm is slow
When the paramedic is trying to send the tracing remotely
What is the frequency response on the EKG?
It filters out excess electricity.
It increases the frequency of the tracing printout.
It filters out noise and artifact.
It increases the speed of the tracing printout.
If you change any of the normal settings on the EKG machine, you must
Document this change on the top of the EKG tracing.
First get permission from the physician.
Use a special type of device to make the change.
Advise the patient this will make her EKG tracing look abnormal.
The normal chart speed for the EKG machine is
10 millimeters/minute
25 millimeters/second
10 millimeters/second
25 millimeters/minute

True
False
Electrodes are small adhesive patches that adhere to the skin and pick up the heart's electrical signals.
True
False
Telemetry monitoring is remote cardiac monitoring.
True
False
60-cycle interference makes the baseline on the EKG tracing look thickened, as though it were drawn with a thick marker.
True
False
Normal chart speed for printing out the EKG is (a) millimeters per second.
Gain controls the (a) of the EKG waves and complexes.
The digital converter is
a heat source in the EKG machine that prevents the patient from getting cold
what converts the analog signal to a digital one
the digital pen that writes the EKG
the on-off button on the EKG machine
Microshock is
a large electrical shock delivered to the outside of the body
prevented by wearing rubber gloves while doing the EKG
not a concern if the patient is dry
a small electrical shock delivered to the inside of the body
Macroshock is delivered by way of a conduit insider the body
True
False
Microshock is a shock caused by 110 volts of electricity going into the patient.
True
False
(a) is an electrical shock delivered into the patient's body by means of a device inside of or attached to the heart, such as a pacemaker.
