Which disorders can cause an extra beat that often originates from a source other than the SA node?(Select all that apply.)
 
  1. Ventricular fibrillation
  2. Premature ventricular contraction
  3. Premature atrial contraction
  4. Atrial fibrillation
  5. Cardiogenic shock

Question 2

A client asks the nurse to explain how a normal heart works. Which statement by the nurse should be included in client teaching?
 
  1. The electrical impulse causes the ventricles to contract, and then the atria contract.
  2. A normal resting heart rate is 50 beats per minute.
  3. For the heart to function properly, the atria must contract simultaneously, sending their blood into the ventricles.
  4. The heart generates electrical impulses that start in the atrioventricular node.

Answer to Question 1

2, 3

Rationale 1: Fibrillation is characterized by very rapid, uncoordinated beats.
Rationale 2: Premature ventricular contraction originates in the ventricles.
Rationale 3: Premature atrial contraction originates in the atria.
Rationale 4: Fibrillation is characterized by very rapid, uncoordinated beats.
Rationale 5: Cardiogenic shock does not cause an extra heartbeat.

Global Rationale: Premature ventricular contraction originates in the ventricles. Premature atrial contraction originates in the atria. Fibrillation is characterized by very rapid, uncoordinated beats. Cardiogenic shock does not cause an extra heartbeat.

Answer to Question 2

3

Rationale 1: The atria contract first, and then the ventricles contract.
Rationale 2: A normal resting heart rate is between 60 and 100 beats per minute.
Rationale 3: For the heart to function properly, the atria must contract simultaneously, sending their blood into the ventricles.
Rationale 4: The impulse is first generated in the sinoatrial node.

Global Rationale: For the heart to function properly, the atria must contract simultaneously, sending their blood into the ventricles. The atria contract first, and then the ventricles contract. A normal resting heart rate is between 60 and 100 beats per minute. The impulse is first generated in the sinoatrial node.
