A patient is nearing the target heart rate during an exercise stress test when he becomes diaphoretic and complains of intense chest pain. Which response from the EKG technician is best?
Stop the test and alert the doctor immediately.
Tell the patient to hold on just a bit longer since hitting the target heart rate will provide better information about why he’s experiencing chest pain.
Stop the test and begin CPR immediately.
Continue the test while administering oxygen.
An intellectually disabled adult patient is frightened of the EKG machine and does not want to lie down for the test. What should the EKG technician do?
Gently but firmly assist the patient to lie down
Tell the patient she will give him a lollipop after the test is over
Offer to show the machine to the patient and answer any questions.
Reschedule the test for a later time.
An EKG tracing in which the P waves are not uniform may indicate a dysrhythmia originating in the
Sinus node
Atria
Bundle Branches
Purkinjie Fibers
Under which of these circumstances may an EKG technician share her interpretation of an EKG with the patient?
If the patient confirms that she understands the technician is not a doctor
If the patient’s EKG shows a potentially lethal dysrhythmia.
If the patient’s EKG is normal
The EKG technician must not share her interpretation with the patient.
Which of these series represents the depolarization and repolarization of the ventricles?
P wave, QRS complex
QRS complex, T wave, U wave
QRS complex, T wave

Measuring vital signs includes
Checking pulse, body temperature, blood pressure, and respirations.
Checking pulse, body temperature, blood pressure, and pain level.
Checking pulse, blood pressure, oxygen saturation, and pain level.
Checking pulse, regularity of heart rhythm, blood pressure, and oxygen saturation.

“Is your name George Disher?”
“What is your last name, George?”
“Can you please state your first and last names?”

When placing electrodes for an EKG on a 5-year-old child where should the technician place the V4 electrode?
On the right side of the chest at the fifth intercostal space at the midclavicular line.
On the left side of the chest at the fifth intercostal space at the midclavicular line.
On the right side of the chest immediately beside the V1 electrode.
On the left side of the chest at the fourth intercostal space just to the left of the sternum.
An EKG technician sees pacing spikes on a patient’s EKG but no electrical activity following the spikes. This is likely due to a pacemaker error known as
Failure to capture
Failure to sense
Failure to fire
Failure to pace
Which leads will show changes if an EKG technician has reversed the right and left arm leads?
Leads II and aVL
Leads I and aVR
Leads V2 and V4
Leads III and aVF
Narrow and wide are words often used to describe
P waves
QT intervals
ST segments
QRS complexes
Which of these sentences demonstrates patient understanding of directions for Holter monitoring?
“I will call the office each time I experience symptoms.”
“I will cover the electrodes, lead wires, and monitor with plastic when I swim or shower.”
“I will change the electrodes every 12 hours.”
“I will make a note in the diary when I exercise.”
The complexes in this EKG tracing could be described as
LA
LL
RA
RL
An ectopic focus is a group of cells in the heart that initiates an impulse
In an abnormal location
Later than it should be
Earlier than it should be
That does not cause a contraction
This patient would require no changes to positioning or electrode placement:
An elderly man with orthopnea
A 35-year-old woman who is 20 weeks pregnant
An 8-year-old child
A 40-year-old man with a full cast on his right leg
Under which of the following circumstances can an EKG technician discuss the details of a patient’s EKG or treatment? (Choose two correct answers.)

When the technician is delivering the completed EKG and the patient’s chart to the cardiologist who ordered the test
When a colleague asks for information about a relative’s health
When the patient’s insurance company calls to confirm that an EKG was ordered and conducted.
When the patient’s employer calls to ask if he is fit to continue working.
After leaving the room to give a patient privacy for gowning, the EKG technician knocks and does not hear a response. She enters cautiously and finds that the patient is unconscious, does not have a pulse, and is not breathing. What is the best response?
Start CPR immediately.
Go find the cardiologist.
Shout out for someone to call 911 and then start CPR.
Get out the automated external defibrillator.
Which of these introductions is appropriate for an EKG technician to make?
“I’m Mario and I’ll be doing your test today.”
“I’m Mario Bedoya. I do EKGs.”
“I’m Mario and I’m helping Dr. Hamlin today with EKGs.”
“I’m Mario Bedoya and I’m an EKG technician.”
