1. What is commonly referred to as a 'widow maker' myocardial infarction?
Circumflex artery blockage
Left anterior descending artery blockage
Coronary artery spasm
Right coronary artery blockage
2. Describe the importance of patient safety protocols during an exercise stress
test.
Patient safety protocols are crucial to prevent adverse events and
ensure the patient's well-being during the test.
Patient safety protocols only apply to the technician, not the patient.
Patient safety protocols are optional and can be ignored if time is
short.
Patient safety protocols are only necessary for patients with known
heart conditions.
3. A treadmill stress test should be stopped:
when the patient requests to stop.
if there is an onset of V-tach.
if the patient begins having chest pain
if there is ST depression > 3mm
all of the above
,4. What is the common cardiac rhythm associated with a high fever due to
infection?
Ventricular fibrillation
Bradycardia
Atrial fibrillation
Sinus tachycardia
5. Describe the importance of obtaining baseline vitals in both sitting and
supine positions before an exercise stress test.
Baseline vitals are not necessary before the test.
Sitting position is only for post-test evaluation.
Obtaining baseline vitals in both positions helps assess the patient's
cardiovascular response and ensures safety during the test.
Only supine position is required for baseline vitals.
6. What is the maximum heart rate that is typically used to conclude an exercise
stress test for a 70-year-old patient?
140 beats per minute
160 beats per minute
150 beats per minute
130 beats per minute
7. Describe the physiological significance of a heart rate of 110 bpm in sinus
tachycardia.
A heart rate of 110 bpm indicates that the heart is beating faster than
normal, which may suggest increased demand for oxygen or stress
, on the body.
A heart rate of 110 bpm is indicative of heart failure.
A heart rate of 110 bpm shows that the heart is functioning at a lower
capacity.
A heart rate of 110 bpm is considered normal and indicates rest.
8. What does the QRS complex represent in an EKG tracing?
Atrial depolarization
Ventricular repolarization
Ventricular depolarization
Atrial repolarization
9. During an exercise stress test, a patient suddenly reports chest pain. What
should the technician do?
Encourage the patient to continue for a few more minutes.
Immediately stop the test and assist the patient.
Record the patient's response and continue the test.
Call for a physician before taking any action.
10. If a patient with a newly implanted pacemaker presents with symptoms of
dizziness and fatigue, what assessment finding would most likely indicate a
failure to capture?
Regular rhythm with normal heart rate
Absence of QRS complexes following pacemaker spikes
Increased heart rate above baseline
Presence of wide QRS complexes
, 11. During a pharmacologic stress test, if a technician notes that the patient only
reaches 75% of their target heart rate, what should the technician do next?
The technician should inform the patient that the test was successful.
The technician should proceed with interpreting the results as valid.
The technician should consider the test incomplete and discuss with
the physician whether to repeat the test or adjust the protocol.
The technician should stop the test immediately and discharge the
patient.
12. Changes to which of the following signifies myocardial injury?
R waves
ST segment
Q waves
T waves
13. What is the correct location for placing lead V2 on a patient during a 12 lead
EKG?
The fourth intercostal space at the left sternal border
The fifth intercostal space at the midclavicular line
The second intercostal space at the right sternal border
The third intercostal space at the left midaxillary line
14. A patient has a sinus tachycardia with a rate of 110 bpm. Which condition is
consistent with this rhythm?
athletic heart
sleeping soundly
