Question 1
Which of the following is the only calculating method available for both regular and
irregular rhythms?
CORRECT ANSWER
The 6- Second method
Question 2
During a stress test, an EKG tech notices the patient appears to be hyperventilating. Which
of the following is an appropriate course of action for the tech?
CORRECT ANSWER
Check the patient's respiratory rate. Checking the rate will allow the CET to confirm
hyperventilation.
Question 3
Which of the following sensitivity settings would produce a calibration box that measures
10mm tall?
CORRECT ANSWER
A sensitivity setting of 1
Question 4

@THE STUDY VAULT
, Which of the following methods for calculating a patient's heart rate from the EKG is
correct?
CORRECT ANSWER
Divide 1,500 by the number of small boxes between two R waves to calculate a full cardiac
cycle.
Question 5
What is the correct order of a complete cardiac cycle in the normal heart?
CORRECT ANSWER
P wave, QRS complex, and T wave
Question 6
While performing a stress test, the patient complains of dizziness. After stopping the test,
which of the following actions should the CET take first:?
CORRECT ANSWER
The CET should notify the physician immediately after stopping the test.
Question 7
Which of the following describes the correct electrode placement for lead V5?
CORRECT ANSWER
Anterior axillary line, 5th intercostal space.
Question 8
Calculate the heart rate in the tracing below using the 1500 method.
