EKG CLEP TEST CONCEPT REVIEW GUIDE
2026 NORMAL AND ABNORMAL ECG
FINDINGS
◉ A patient presents alert and oriented, but an EKG technician finds
that all the waveforms are negative in Lead I. The technician should
check the cable connections for which the following limb electrodes?
Answer: Right arm and left arm
◉ An EKG tech detects U waves and the patient reports chest pain
and discomfort. What is the appropriate action?
Answer: Notify the patient's physician
◉ An EKG is showing a rhythm that the Tech is not familiar with.
What should they do next?
Answer: verify proper lead placement
◉ Which of the following is the correct sensitivity setting to create
an EKG standardization mark of 5 mm?
Answer: 1/2
◉ Which activity should the EKG tech tell a patient to record in his
Holter monitor daily?
,Answer: Running
◉ The EKG tech is educating a patient on when she should push the
event button while wearing a Holter monitor. What shows that she
understands?
Answer: "I will push the event button if I'm experiencing
discomfort."
◉ Which is the only calculating method that available for both
regular & irregular rhythms?
Answer: Six-Second method
◉ During a stress test, an EKG tech notices the patient appears to be
hyperventilating. What is the best action?
Answer: Check the patient's respiratory rate
◉ Which of the following sensitivity settings would produce a
calibration box that measures 10 mm tall?
Answer: 1
◉ Which of the following methods for calculating a patient's heart
rate from the EKG is correct?
Answer: Divide 1,500 by the number of small boxes between two R
waves
, ◉ What is the correct order of a complete cardiac cycle in the
normal heart?
Answer: P wave, QRS complex, and T wave
◉ While performing a stress test, the patient complains of dizziness.
After stopping the test, which of the following actions should the
CET take first?
Answer: Notify the physician

of the following is the patient's heart rate?
Answer: 60 bpm (This rate is calculated using the 300 method, in
which 300 is divided by the number of large boxes. 300/5=60
