Chapter 29 Davis Edge
A nurse finds the patient is unresponsive with no pulse or blood pressure. Which dysrhythmia does the nurse anticipate? Normal sinus rhythm Asystole Second degree heart block, type I Premature ventricular contractions (PVCs), symptomatic
Asystole
For each of these rhythms, place the priority action in the correct order. Determine level of consciousness. Assess blood pressure. Defibrillate. Document.
Defibrillate. Determine level of consciousness. Assess blood pressure. Document.
The nurse is caring for a patient who suddenly develops dizziness and sweating. He has had similar symptoms in the past and has fainted. Which type of heart block should the nurse consider is causing these symptoms? First-degree atrioventricular block (AVB) Second-degree, type I, atrioventricular block (AVB), asymptomatic Second-degree, type I, atrioventricular block (AVB), symptomatic Third-degree complete heart block, asymptomatic
Second-degree, type I, atrioventricular block (AVB), symptomatic
A nurse overhears another team member saying that atrial fibrillation begins in the atrioventricular (AV) node of the heart. What action should the nurse take? Stop the team member and correct their comment. Allow them to finish their comments as being correct. Share with another colleague what you overheard. Confirm the information as being accurate with an internet search.
Stop the team member and correct their comment. Atrial fibrillation is multiple areas of firing throughout the atria of the heart
An RN is teaching a nursing student about the heart rates in patients with atrial fibrillation. Which statement made by the nursing student indicates the need for further teaching? "Atrial rates in patients with atrial fibrillation can range from 300 to 600 beats per minute." "A heart rate of 110 beats per minute is considered to be uncontrolled atrial fibrillation." "Heart rate of 95 beats per minute indicates atrial fibrillation with rapid ventricular response." "When the atrioventricular (AV) node maintains the heart rate at less than 100 beats per minute, the condition is referred to as controlled atrial fibrillation."
"Heart rate of 95 beats per minute indicates atrial fibrillation with rapid ventricular response."
While assessing the electrocardiogram (ECG) report of a patient, the nurse observes that there is an absence of P waves and the QRS complex is narrow with irregular RR intervals. Which dysrhythmia is the patient experiencing? Atrial fibrillation Sinus tachycardia Sinus bradycardia Junctional tachycardia
Atrial fibrillation
Which are true regarding the QRS wave? Select all that apply. The QRS wave is the first wave that is normally seen in patients. The QRS wave represents ventricular depolarization. Normal QRS waves are usually rounded in width. Wide QRS waves may indicate that there is a block in the ventricles. QRS waves can take on many different forms.

Which are true regarding a third-degree atrioventricular (AV) or complete heart block? Select all that apply. The P waves will be equal to the QRS complexes. The atrial rate is between 60 and 100 bpm; ventricular rate is less than or equal to 40 bpm. The P waves should march throughout the rhythm strip at an irregular rate. The ventricles and atria do not have any communication. The permanent pacemaker may be inserted as per the order.
