Verified Answers | Latest Update | Graded A+
1. Describe how the characteristics of 3rd Degree Heart Block with Bundle
Branch Block affect the heart's overall function.
The complete dissociation between atrial and ventricular rhythms
leads to inefficient heart function and reduced cardiac output.
The rapid atrial contractions increase overall cardiac efficiency.
The consistent ventricular rate maintains adequate blood flow.
The regular atrial rhythm ensures effective ventricular filling.
2. Ventricular fibrillation appears on the ECG monitor as having:
Narrow QRSC
P waves interspersed between bizarre-looking QRSCs
Electrical signals that are the same height
An overall pattern that appears irregularly shaped, chaotic, and
lacks any regular repeating features
3. Describe how Sinus Rhythm with Pause differs from normal Sinus Rhythm.
Sinus Rhythm with Pause shows irregular ventricular rhythms, unlike
normal Sinus Rhythm.
Sinus Rhythm with Pause includes periods of no electrical activity,
while normal Sinus Rhythm maintains consistent pacing.
Sinus Rhythm with Pause is characterized by a higher amplitude of
waves compared to normal Sinus Rhythm.
Sinus Rhythm with Pause has a faster heart rate than normal Sinus
Rhythm.
,4. Which of the following is true regarding accelerated idioventricular rhythms?
The PR interval is greater than 0.12 seconds
It is very common after a myocardial infarction
It is always regular
Immediate cardiopulmonary resuscitation is required
5. Describe how 3rd Degree Heart Block affects the relationship between atrial
and ventricular rhythms.
In 3rd Degree Heart Block, the ventricular rhythm is dependent on the
atrial rhythm.
In 3rd Degree Heart Block, the atrial and ventricular rhythms are both
regular and synchronized.
In 3rd Degree Heart Block, the atrial rhythm is faster than the
ventricular rhythm but they are still synchronized.
In 3rd Degree Heart Block, there is no communication between the
atria and ventricles, leading to independent rhythms.
6. If a patient presents with NSR and Multifocal PVCs, what clinical actions
should be considered?
Increase the patient's physical activity to improve heart function.
Evaluate for potential underlying heart conditions and monitor the
patient closely.
Ignore the PVCs as they are not clinically significant.
Administer immediate defibrillation to restore normal rhythm.
7. What does 100% AV Paced indicate in EKG analysis?
, There is a complete heart block.
The heart is experiencing atrial fibrillation.
The heart is in normal sinus rhythm.
The heart is being paced by an artificial pacemaker at the
atrioventricular node.
8. What is the primary characteristic of Ventricular Fibrillation as observed on an
EKG strip?
Slow, consistent heart rate
Regular, rhythmic contractions
Irregular, chaotic electrical activity
P waves present with normal QRS complexes
9. An NSR can be identified by: 1. A resting rate of 60-100 beats/min in an adult
2. A P wave before every QRS complex 3. A regular rhythm 4. A QRS complex
after every P wave 5. An upright T wave in lead II
2 and 4 only
2, 3, and 4 only
1, 2, 3, and 5 only
1, 2, 3, 4, 5
10. What is a key characteristic of 2nd Degree Heart Block type II as observed
in an EKG strip?
Intermittent non-conducted P waves
Regularly spaced QRS complexes
Prolonged PR interval
, Variable ventricular rate
11. In a patient with Uncontrolled A-Fib, what would you expect to observe on
an EKG strip compared to a patient with Junctional Rhythm?
An irregularly irregular rhythm with no discernible P waves in
Uncontrolled A-Fib.
A regular rhythm with visible P waves in Junctional Rhythm.
A consistent heart rate in both conditions.
A normal QRS complex in both conditions.
12. If a patient presents with symptoms of palpitations and an EKG shows
NCSVT, what would be the most appropriate initial management step?
Immediately administer antiarrhythmic medication.
Assess the patient's hemodynamic stability.
Increase the patient's fluid intake.
Perform a cardioversion without further assessment.
13. What rhythm occurs when a total block develops at or below the AV node?
second degree AV block type 2
third degree AV block
fascicular block
bundle branch block
14. A nurse identifies a "sawtooth" pattern on the EKG monitor and suspects
atrial flutter. Why is atrial flutter concerning?
It can lead to rapid ventricular response and decreased cardiac
output.
