-Guarantee passing score -36 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: Junctional rhythms occur because the electrical impulse comes from the AV
node instead of the:
Answer:
SA node Question 2: What symptoms will a patient have if PJCs occur more than four to six times per minute?
Answer:
Hypotension, irregular pulse Question 3: The criteria needed to classify a dysrhythmia as supraventricular tachycardia is:
Answer:
dentical atrial and ventricular rates
Question 4: What is the heart rate for junctional escape rhythm?
Answer:
40 to 60 beats per minute
Question 5: hich of the following dysrhythmias is NOT considered part of the supraventricular tachycardia classification?
Answer:
Atrial fibrillation Question 6: What symptom might a stable patient complain about when experiencing supraventricular tachycardia?
Answer:
Palpitations Question 7: he term retrograde means:
Answer:
Backward Question 8: The condition in which the patient's blood pressure is not adequate to maintain
good blood supply to the vital organs is known as:
Answer:
Hypotension
Question 9: What is unique about junctional escape rhythm?
Answer:
The P wave may occur before, during, or after the QRS and is inverted <-- means buried in
Question 10: What is the heart rate of junctional tachycardia rhythm?
Answer:
100 to 150 beats per minute Question 11: Why is it unlikely that a patient would have symptoms of low cardiac output with accelerated junctional rhythm?
Answer:
The heart rate is the same as normal sinus rhythm
Question 12: What is unique about premature junctional complexes?
Answer:
PJCs have an irregular rhythm; the P wave is inverted and may appear before, during, or after the QRS complex
Question 13: This occurs before the next expected sinus impulse, causing an irregularity:
Answer:
Premature junctional complex Question 14: A fast, irregular heartbeat sensation felt by the patient is known as:
Answer:
Palpitations Question 15: Identify the following rhythm:
Answer:
Supraventricular tachycardia Question 16: Why are the P waves inverted or buried within the QRS complex in junctional dysrhythmias?
Answer:
The P wave is inverted due to retrograde depolarization of the atria Question 17: With junctional rhythms, the electrical current is initiated from the:
Answer:
AV junction
Question 18: 1. What is the normal, inherent rate of the AV node?
Answer:
40 to 60 beats per minute Question 19: What rhythm occurs when the SA node fails to initiate the electrical activity and one of the backup pacemaker sites takes over?
Answer:
Escape rhythm Question 20: What causes the inverted P wave morphology found with junctional rhythms?
Answer:
Electrical impulses are coming from the AV node instead of the SA node, causing depolarization of the atria to flow retrograde
Question 21: What common symptoms might a patient complain about with supraventricular tachycardia?
Answer:
- Heart racing
- Heart fluttering
- "Just not feeling right"
- All of the above <---
Question 22: What is the difference between premature junctional complexes and junctional escape rhythm?
Answer:
- Junctional escape rhythm has a rate of 40 to 60 bpm; PJC rate depends on the underlying rhythm
- Junctional escape rhythm has P-P and R-R intervals that are regular and similar
- PJCs typically have an irregular rhythm
- All of the above
Question 23: Which of the following originates from the AV junction?
Answer:
Atrial flutter Question 24: What is the difference between accelerated junctional rhythm and junctional tachycardia rhythm?
Answer:
Heart rate
Question 25: What is the heart rate range for accelerated junctional rhythm?
Answer:
60 to 100 beats per minute
