Graded A+
1. If a patient exhibits signs of myocardial ischemia, how would bipolar ECG
leads be utilized in their assessment?
To measure the patient's blood pressure during exercise.
To assess the physical size of the heart chambers.
To provide a single lead view of heart activity.
To identify changes in the ST segment that indicate ischemia.
2. Describe the role of Cardiolite in diagnosing cardiac conditions.
Cardiolite is used to measure heart rate variability.
Cardiolite is used in nuclear stress tests to visualize blood flow to
the heart muscle, helping to identify areas of ischemia.
Cardiolite is a type of treadmill used for stress testing.
Cardiolite is a medication that lowers blood pressure during tests.
3. A second degree type I AV block is defined by:
A PR interval that gets progressively longer until there is a dropped
QRS complex.
A prolongued PR interval with randomly dropped QRS complex.
A road block to stop all terrain vehicles from accessing a trail.
A prolonged PR interval.
4. The most common methods of stress testing include________________ _.
treadmill and bicycle ergometer
, arm ergometer and treadmill
bicycle ergometer and stair-stepper
stair-stepper and arm ergometer
5. Describe how AV dissociation affects the relationship between atrial and
ventricular activity as seen on an ECG.
AV dissociation is characterized by a consistent PR interval.
AV dissociation shows that atrial and ventricular activities are
independent, with P waves occurring at a different rate than QRS
complexes.
AV dissociation results in a regular rhythm with no variations in heart
rate.
AV dissociation indicates that the atria and ventricles contract
simultaneously.
6. A normal P-wave characteristically
is a reflection of right atrial excitation
has duration of 1 sec and an amplitude of .2mv
has duration of .1 sec and an amplitude of .2mv
has duration of .1 sec and amplitude of 10mv
7. What is the primary event that occurs during the 3rd phase of the cardiac
cycle?
Atrial contraction
Ventricular filling
Ventricular ejection
, Isovolumetric relaxation
8. How does the nurse differentiate between atrial fibrillation and atrial flutter
when interpreting cardiac rhythms on a telemetry monitor?
Atrial fibrillation has a regular, sawtooth pattern.
Atrial fibrillation typically has a heart rate above 150 bpm.
Atrial flutter has a characteristic "flutter" or "sawtooth" appearance.
Atrial flutter presents with an irregular rhythm.
9. Describe how the Thallium Stress Test contributes to the diagnosis of cardiac
conditions.
The Thallium Stress Test helps identify areas of reduced blood flow
to the heart, indicating potential ischemia.
The Thallium Stress Test measures electrical activity in the heart.
The Thallium Stress Test evaluates the effectiveness of medications.
The Thallium Stress Test determines the size of the heart.
10. A patient presents with ST depression on an ECG but has no history of
coronary artery disease. Which non-coronary condition might you
investigate further?
Coronary artery disease
Hypokalemia
Heart failure
Myocardial infarction
11. Describe the significance of R-R intervals in determining heart rate from an
ECG.
, R-R intervals indicate the duration of ventricular contraction only.
R-R intervals show the electrical activity of the atria.
R-R intervals are used to measure blood pressure.
R-R intervals represent the time between heartbeats, allowing for
heart rate calculation.
12. Based on the diagram of the cardiac conduction system, which structure is
responsible for initiating the electrical impulse of the heart?
Purkinje fibers
AV node
SA node
Bundle of His
13. Describe the significance of the QT interval in assessing cardiac health.
The QT interval measures the heart rate variability.
The QT interval is used to determine the size of the heart chambers.
The QT interval indicates the strength of the heart's contraction.
