D. Ventricular Flutter
7. A patient is diagnosed with complete heart block. The most appropriate treatment for this
patient would be…
A. Administer 2L oxygen
B. Increase dose of digoxin
*C. Cardiac pacing
D. Restrict IV fluid intake
8. A patient is noted to be in sinus bradycardia with a rate of 42 beats per minute with
symptomatic hypotension. This condition would be best treated by
A. Nitroglycerine
B. Beta Blockers
C. Aspirin
*D. Atropine
9. An EKG is a measurement of
* A. The electrical activity of cardiac muscle
B. The contraction of cardiac muscle
C. The strength of cardiac muscle
D. All of the above
10. Your patient is complaining of palpitations. The patient’s EKG shows a heart rate of 120,
regular rhythm, PR = 0.16, QRS complex = 0.08, and A:V conduction ratio is 1:1. The most
appropriate nursing intervention to perform next would be
A. Synchronized Cardioversion
*B. Assess patient’s blood pressure
C. Apply 2L oxygen by nasal cannula
D. Administer Atropine 1mg IVP
11. A patient’s EKG demonstrates a rate of 35 and is in 2nd degree type II AV Block. The
expected treatment for this patient would be
A. Atropine 10 mg IVP
B. Metoprolol 10 mg IVP
C. Amlodipine 10 mg PO

12. During discharge teaching for a patient who was newly diagnosed with atrial fibrillation, the
nurse recognizes the need for more teaching when the patient states
A. I am starting on Warfarin to prevent blood clots
*B. I should only take my Warfarin when I have chest pain
C. Atrial fibrillation can lead to dizziness or low blood pressure
D. I should take Warfarin at the same time every day
13. Under usual circumstances, after an impulse is generated in the SA node, it
A. moves from left to right and top to bottom
B. travels through the AV node to the Bundle Branches
C. leads to cardiac muscle contraction
*D. All of the above
14. 2nd Degree Type I AV Block
A. Is also known as Wenckebach
B. Is usually a temporary condition that is asymptomatic
C. Has a pattern of a prolonged PR interval until a QRS complex is dropped

C. Chest compressions
D. Administer 10 mg Atropine IVP
19. Ventricular fibrillation is concerning because
A. It can lead to a life threatening arrhythmia
B. The atrial and ventricular contractions are no longer coordinated
*C. During this rhythm there is no cardiac output
D. Conduction through the bundle branches is prolonged
20. A patient’s EKG in Lead II demonstrates a rate of 78, regular, PR 0.12 seconds, a QRS and
0.10 seconds, and an A:V conduction ratio of 1:1. Your analysis of this rhythm would be
