A) Activate the catheterization lab team for elevated T waves in Lead II.

B) Print the electrocardiogram and notify the provider of the client’s pain.

C) Print the electrocardiogram and place in the client’s health record.

D) Verify lead connections and perform a new 12-lead electrocardiogram.

2. The nurse receives an order to perform a 12-lead electrocardiogram on a client in the clinic. What is the correct order for applying electrodes?

A) abrade the skin, cleanse with alcohol, wipe with cloth, apply electrodes to skin

B) perform hand hygiene, apply electrodes, connect leads, print electrocardiogram

C) position client, apply leads, remove electrodes, cleanse with alcohol after removal

D) wipe skin with cloth, cleanse with alcohol, apply electrodes to skin

3. The nurse is connecting the client to a 5-lead cardiac monitor. The cardiac leads are color coated as such: Green, Black, Red, White, Brown

Select the correct number on the body diagram below that indicates where the brown lead should be placed.

4. The educator is discussing the cardiac conduction cycle during lecture. Which statement by the student indicates a need for additional learning?

A) “Atrial repolarization is usually concealed and not noticeable on the rhythm strip.”

B) “Depolarization involves activation of the action potentials of the ventricles.”

C) “The atrioventricular node sends electrical impulses to the Purkinje fibers.”

D) “The sinoatrial node sets the heart rate as the primary pacemaker.”

5. While conducting a 12-lead electrocardiogram the electrodes do not adhere to the client. Which of the following are appropriate steps to take?

A) Clip the client’s hair at the lead placement sites.

B) Have the client hold the electrodes down on their skin.

C) Prep the placement sites with betadine and dry completely

D) Tape the electrodes in place to ensure adherence.

6. All of the following are key landmarks used with 12-lead electrocardiogram lead placement except:

A) Left 4th intercostal space, sternal border

B) Right 4th intercostal space, sternal border

C) Left 5th intercostal space, midaxillary line

D) Right 5th intercostal space, midclavicular line

What area highlighted on the rhythm strips below represents ventricular repolarization of the cardiac conduction cycle?

8. The nurse is caring for a client with an implanted pacemaker who needs an electrocardiogram. When considering lead placement for a 12-lead electrocardiogram on this client, the nurse recognizes that:

A) the cardiac leads should be shifted downward to prevent interference.

B) the cardiac leads should be placed in the normal positions.

C) the precordial leads should be shifted upward to prevent interference.

D) the precordial leads should be repositioned to the right side of the chest.

9. A client admitted to the unit with pneumonia, has a temperature of 102.6°F and is diaphoretic. The client’s monitor is alarming with the image below. What is the nurse’s priority action to take?

A) Administer a PRN antipyretic that is ordered and cool the patient.

B) Notify the provider that the client is shivering and the monitor is alarming

C) Remove and reapply the electrodes to dry and clean skin.

D) Silence the alarm so that it does not disturb the client.

10. A client who is experiencing a cardiac emergency is rushed into the emergency department. The nurse conducts a 12-lead electrocardiogram for this client and realizes which of the following?

A) The limb leads have disconnected from the client.

B) The precordial leads have disconnected from the client.

C) The electrodes have poor connection with the client’s skin.

D) The client has no pulse and is asystole on the monitor.
