  c. 100-150 beats per minute
  d. 80-120 beats per minute
2. In Sinus Rhythm, Sinus Bradycardia, and Sinus Tachycardia, what is the QRS complex to P wave ratio?
  a. 1:1
  b. 2:1
  c. 3:1
  d. 4:1
3. Where is the pacemaker site for Sinus Rhythm, Sinus Bradycardia, and Sinus Tachycardia?
  a. SA node
  b. AV node
  c. Purkinji Fibers
  d. Bundle of His
4. What rhythm can be caused by exercise?
  a. Sinus Bradycardia
  b. Sinus Rhythm
  c. Sinus Tachycardia
  d. None of the above
5. At what rate does Supraventricular Tachycardia (SVT) have to exceed to be called SVT?
  a. 100 beats per minute
  b. 110 beats per minute
  c. 150 beats per minute
  d. Twice the resting pulse rate
6. If your patient is having Supraventricular Tachycardia, what do you do?
  a. Put the patient in trendelenburg
  b. Administer oxygen, call the MD, obtain vital signs,consider cardioversion, consider verapamil or adenosine, and prepare for a code
  c. Nothing, this is a normal acceptable rhythm
7. How many P wave morphologies are required to consider a rhythm to be a Wandering Atrial Pacemaker?
  a. At least two different P wave morphologies
  b. At least three different PR intervals
  c. One upright morphology and at least two biphasic morphologies
  d. At least three different P wave morphologies
8. Is Atrial Fibrillation irregular in pattern?
  a. Yes
  b. No
  c. Sometimes but not often
  d. Only when patients are stressed out, and drinking coffee
9. What is the rate of controlled Atrial Fibrillation?
  a. 40-6- beats per minute
  b. Less than 100 beats per minute
  c. Greater than 150 beats per minute
  d. Less than 40 beats per minute
10. Should you notify the MD when you detect that your patient has an irregular heart beat, EKG confirms that it is Atril Fibrillation, and your patient does not have a history of Atril Fibrillation?
  a. Yes, call the MD
  b. No, it is not signigicant
  c. Never call the MD on this
11. What is the distinguishing factor of Atrial Flutter?
  a. A sawtooth pattern on the base line
  b. The dropping of QRS complexes
  c. The patient is pulseless
12. In Atrial Fibrillation, where is the site of the P waves?
  a. The SA node
  b. The AV node
  c. There are no P waves because there are many ectopic foci in the atria causing a rapid discharge of impulses at a rate of greater than 400 beats per minute
