MA NHA Module 9 Practice 1

The first step in preparing a patient for an EKG is:

• Cleaning the skin to ensure proper electrode contact

• Attaching leads to the chest

• Explaining the procedure

• Positioning the patient on the EKG table

What should you check before performing an EKG? Answer: Electrode placement.

• Patient identification

• Electrode placement

• Skin condition

• Lead cable connection

Identify two supplies needed for EKG testing.

• Electrodes and lead wires

• Electrodes and defibrillators

• Syringes and bandages

• Stethoscopes and thermometers

The patient is positioned in a supine position with the chest exposed and limbs positioned appropriately for an EKG.

• Supine position with chest exposed and limbs at rest

• Sitting upright with arms raised

• Standing with arms abducted

• Prone position with arms extended

Signs of distress to monitor during an EKG include abnormal heart rhythms, ST-segment changes, and irregular heartbeats.

• Only abnormal heart rate

• Abnormal heart rhythms, ST-segment changes, and irregular heartbeats

• Only ST-segment changes

• None

The types of leads used in EKGs are:

• Bipolar and unipolar leads

• Only bipolar leads

• Only unipolar leads

• Bipolar, unipolar, and tripolar leads

Lim electrodes placement: should be on the wrists and ankles.

• On the chest

• On the abdomen

• On the wrists and ankles

• On the back

Electrode placement affects EKG results by altering the recorded amplitude, duration, and morphology of the heart's electrical signals.

• It alters the recorded amplitude, duration, and morphology of the heart's electrical signals.

• It has no effect on the EKG results.

• It only affects the amplitude of the electrical signals.

• It only changes the EKG paper speed.

The importance of anatomical electrode placement is:

• Accurate placement ensures optimal measurement and interpretation of physiological signals

• It does not affect physiological measurements

• It is only important for cosmetic reasons

• It solely influences electrode durability

Chest leads record the electrical activity from the chest region while limb leads record the activity from the limbs. Which statement correctly describes the difference between chest leads and limb leads?

• Chest leads record from the chest region and limb leads record from the limbs.

• Chest leads record from the limbs and limb leads record from the chest.

• Both chest leads and limb leads record the same electrical activity.

• There is no difference between chest leads and limb leads.
