"Press the record button on the device when you begin to feel dizzy or have chest pain." (A
trans telephonic monitor with loop memory creates a recording of the electrical activity of the
heart for the segment of time before, during, and after an episode when the patient presses the
record button.) - ANS ✔✔1. An EKG technician is instructing a patient about the use of a trans
telephonic monitor with loop memory. Which of the following instructions should the
technician include?
Assume implied consent because the patient's condition is considered critical. (The technician
should assume implied consent and perform the EKG in an emergency, such as an unconscious
patient arriving at the emergency department.) - ANS ✔✔2. An EKG technician has a
prescription to perform an EKG tracing on an older adult patient who is unconscious upon
arrival at the emergency department. Which of the following actions should the technician
take?
Divide 300 by the number of large boxes between two R waves. (The technician should use the
300 method to calculate a full cardiac cycle.) - ANS ✔✔3. Which of the following methods
should an EKG technician use to calculate a patient's heart rate from the EKG tracing?
Apply silver electrodes that can be checked daily. (The technician should apply silver electrodes
to a client who is scheduled to receive a series of EKG readings because these electrodes can be
left in place and only need to be checked daily.) - ANS ✔✔4. An EKG technician is caring for a
patient who is admitted to an inpatient facility for chest pain. Which of the following actions
should the technician take when performing a series of EKG readings for this patient?
Hand delivering the EKG to the patient's provider. (The technician should recognize that hand-
delivering the records to the provider is one way of protecting the patient's privacy.) - ANS
✔✔5. An EKG technician has performed an EKG on a patient. Which of the following actions by
the technician would protect the patient's health information in accordance with HIPAA
regulations?
,Check that the tracing is free from artifacts and then disconnect the patient from the machine.
(This is the action the technician should take next because verification of the recording should
be done prior to removing the electrodes.) - ANS ✔✔6. After completing a standard 12 lead EKG
on a patient, which of the following actions should an EKG technician take next?
Have the patient repeat the instructions back. (The technician should have the patient repeat
the instructions back to determine if the patient understands. The technician should also have
the patient make the first entry into the diary.) - ANS ✔✔7. Which of the following is the most
effective technique for an EKG technician to use to verify that a patient understands the Holter
monitor instructions?
Beginning of the Q wave to the end of the S wave. - ANS ✔✔8. Which of the following sections
of the EKG tracing should an EKG technician use to measure the QRS complex?
Leads, I,II,III. (These bipolar leads are represented by Einthoven's triangle.) - ANS ✔✔9. Which
of the following lead groups form Einthoven's triangle?
Leads, I,II,III. (These are the standard bipolar leads.) - ANS ✔✔10. Which of the following lead
groups are bipolar leads?
P wave, QRS complex, T wave. (This describes a complete cardiac cycle.) - ANS ✔✔11. Which of
the following describes a complete cardiac cycle in a healthy heart?
Verify proper lead placement. (The technician should ensure correct lead placement. Improper
lead placement will display an inaccurate tracing.) - ANS ✔✔12. A serial EKG tracing shows a
rhythm that does not match the last tracing that the EKG technician performed. Which of the
following actions should the technician take first?
P wave (The P wave is the result of atrial depolarization.) - ANS ✔✔13. Which of the following is
the result of atrial depolarization?
, "I should record spontaneous symptoms unrelated to an activity." (The patient should record all
feelings, symptoms, and activities as a part of the Holter monitor diary.) - ANS ✔✔14. A patient
has a prescription to wear a Holter monitor for 24 hr. Which of the following statements by the
patient indicates an understanding of home care instructions?
Third-degree AV block (In third-degree AV block, the technician must observe the patient for
signs and symptoms of decreased cardiac output. ) - ANS ✔✔15. For which of the following
types of heart block should an EKG technician observe the patient for signs and symptoms of
decreased cardiac output that could lead to cardiac arrest?
Gain (The technician should use the gain control to adjust the height of the waveform.) - ANS
✔✔16. Which of the following EKG machine functions should an EKG technician use to control
and regulate the height of EKG waveforms on the tracing?
Depressed ST segment (The technician should recognize that a client who is experiencing
myocardial ischemia is likely to have a depressed ST segment.) - ANS ✔✔17. An EKG technician
is performing a stress test for a patient. Which of the following EKG changes indicates that the
patient is beginning to show signs of myocardial ischemia?
Holter monitor (A Holter monitor is typically prescribed for patients who experience
palpitations, syncope, dizziness, chest pain, lightheadedness, or are taking antidysrhythmics.) -
ANS ✔✔18. An EKG technician is caring for a patient who is experiencing heart palpitations.
Which of the following interventions should the technician expect the provider to prescribe?
85% to 100% (When a patient has reached 85% to 100% of the target heart rate, the stress test
can be terminated. The formula for a patient's target heart rate is obtained by subtracting the
patient's age from 220 and multiplying it by 0.85. ) - ANS ✔✔19. When performing a stress test,
an EKG technician should recognize that the test can be stopped when the patient reaches what
percentage of their target heart rate?
50 mm/second (An increased heart rate will make it difficult to read the tracing. The technician
should increase the speed control to 50 mm/second.) - ANS ✔✔20. An EKG technician is
