Sinus Arrest, Sinus Block, and Sick Sinus Syndrome Cardiac Review – Slides

 

CARDIOVASCULAR NCLEX QUIZ QUESTIONS

 

Question 1:  You begin your shift and assess an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.10 seconds, and the QRS complexes are 0.08 seconds. The overall heart rate is 80 beats per minute but there is a pause after the QRS complex. The nurse assesses the cardiac rhythm as:

A. Sick Sinus Syndrome

B. Sinus Arrest

C. First Degree Heart Block

D. Sinus Tachycardia

 

Question 2: After watching the cardiac monitor, you notice the rhythm has suddenly changed. P waves are present and 0.10 seconds, the QRS complexes are 0.08 seconds, and the ventricular rate is irregular but 50 beats per minute with runs of 120 beats per minute. What rhythm is this?

A. Sinus Rhythm

B. Sinus Tachycardia

C. Sinus Bradycardia

D. Sick Sinus Syndrome

 

Question 3: True or False: Treatment for sinus arrest is treated based on treating the underlying cause and follows the sinus bradycardia treatment algorithm

 

Question 4: You enter a patients room and the patient is in sinus arrest and symptomatic. What medication would you consider when making a recommendation to the provider for treatment?

A. Amiodarone

B. Cardizem

C. Atropine Sulfate

D. Agratroban

 

Question 5: True or False: When administrating atropine, it is important to have the code cart available due to the potential for paradoxical slowing.
