  • Atrial fibrillation

  • Ventricular fibrillation

Explanation

Question 2 of 15

1

Primary blood supply to the AV node and SA node:

Select one of the following:

  • Right coronary artery

  • Left coronary artery

  • Circumflex artery

  • Left anterior descending artery

Explanation

Question 3 of 15

1

All the following are correct inherent beats except:

Select one of the following:

  • SA node at 100-110 bpm

  • SA node at 60-80 bpm

  • AV node at 40-60 bpm

  • Bundle of His at 20-40 bpm

Explanation

Question 4 of 15

1

What is the correct order in which heart sounds are heard?

Select one of the following:

  • S1, S2, S3, S4

  • S4, S1, S2, S3

  • S1, S4, S2, S3

  • S3, S1, S2, S4

Explanation

Question 5 of 15

1

Which heart sound may disappear when a patient sits up or stands and is considered abnormal in adults over 40 y/o?

Select one of the following:

  • S1

  • S4

  • S3

  • S2

Explanation

Question 6 of 15

1

All of the following cause splits except:

Select one of the following:

  • Bundle branch block

  • Ventral septal defect

  • Irritable foci

  • Valve dysfunction or blood flow alterations

Explanation

Question 7 of 15

1

You are listening to a 6 y/o female heart beat and notice the rate increases with inspiration and decreases with expiration. She has no other s/s. What do you do?

Select one of the following:

  • Nothing, this can be a normal finding for this age

  • Administer nitroglycerin tablets to the patient

  • Immediately transport the patient to the ER

  • Stop treatment and reschedule for another day

Explanation

Question 8 of 15

1

A patient’s ECG shows a PR interval < 0.12 and a regular QRS rate > 100. The patient presents with a rapid and regular pulse and decreased cardiac output. This patient has what type of arrhythmia?

Select one of the following:

  • Wandering atrial pacemaker

  • Atrial premature beat

  • Atrial tachycardia

  • Atrial flutter

Explanation

Question 9 of 15

1

Individuals with atrial fibrillation are at increased risk of stroke because:

Select one of the following:

  • There is less blood supply to the brain

  • The heart is weaker

  • The vibrations inhibit vitamin K binding for the coagulation cascade

  • There is less atrial kick leading to blood being left behind in the atria to form a clot

Explanation

Question 10 of 15

1

Find the true statement:

Select one of the following:

  • Multifocal premature ventricular contractions look the same as bigeminy and come from the same spot

  • Ventricular premature contractions always require treatment

  • Patients with a ventricular premature contraction may have a pause in pulse followed by a strong beat or may complain of palpitations or skipped beats

  • Ventricular premature contractions more than 6 per minute or more than 3 in a row are no cause for concern

Explanation

Question 11 of 15

1

A patient in the hospital complains of heart palpitations, dyspnea, dizziness, and appears anxious and is sweating. This patient is experiencing:

Select one of the following:

  • Ventricular premature contraction

  • Ventricular tachycardia

  • Ventricular fibrillation

  • asystole

Explanation

Question 12 of 15

1

What is the correct order of progression?

Select one of the following:

  • Ventricular premature contraction (> 3 in a row), ventricular fibrillation, asystole, ventricular tachycardia

  • Ventricular tachycardia, quadrigeminy, ventricular fibrillation, asystole

  • Bigeminy, ventricular fibrillation, ventricular tachycardia, asystole

  • Ventricular premature contraction (> 3 in a row), ventricular tachycardia, ventricular fibrillation, asystole

Explanation

Question 13 of 15

1

Fixed P-R interval with a dropped QRS every third beat, may drop several QRS waves in a row, typically fixed with a pacemaker. Identify the arrhythmia:

Select one of the following:

  • 1st degree AV block

  • 2nd degree AV block type 2

  • 2nd degree AV block type 1

  • Sinus block (aka “skipped beat”)

Explanation

Question 14 of 15

1

ECG presents as regular P and QRS waves that appear out of sync with each other. s/s include slow HR (< 60 bpm), drop in CO, and possible ventricular fibrillation. What arrhythmia may proceed this type of block?

Select one of the following:

  • 2nd degree AV block type 2

  • 2nd degree AV block type 1

  • 1st degree AV block

  • Left bundle branch block

Explanation

Question 15 of 15

1

You are seeing a 65 y/o male. Upon reading the ECG you notice he has a widened Q wave and an elevated ST wave on leads V1 and V2. What do you do?

Select one of the following:

  • Ask the patient if he has had any ischemic heart attacks recently

  • Do not perform treatment and reschedule for another day

  • Do nothing and treat him like any other patient

  • Verify with nursing or the doctor to see if they are aware that this patient has had an MI
