Question 1

Types of Mechanical Heart Failure

Answer 1

• Direct Trauma
• Chronic Hypertension
• Loss of Cardiac Muscle Structure
• Loss of Proper Heart Valve Function
• Myocardial Infarction
• Pulseless Electrical Activity (PEA)

Question 2

Asystole

Answer 2

The complete failure of the heart’s electrical conduction system.

Question 3

Types of Dysrhythmias

Answer 3

• Asystole
• Ventricular Tachycardia
• Ventricular Fibrillation

Question 4

Effects of Cardiac Arrest

Answer 4

• Heart Fails to Pump
• Circulation of Blood Stops
• Cells are Deprived of Oxygen/Nutrients
• Organs are Damaged (and Eventually Fail)
• Patient Will Die if Uncorrected

Question 5

Sudden Unexpected Infant Death (SUID)

Answer 5

The sudden and unexpected death of an infant (i.e. a baby less than 1 year of age) in which the cause of death was not obvious prior to investigation.

Question 6

Commonly Reported Types of SUID

Answer 6

• Sudden Infant Death Syndrome (SID)
• Unknown Cause
• Accidental Suffocation/Strangulation in Bed

Question 7

Chain of Survival (Cardiac Arrest)

Answer 7

1. Recognition and Activation of the Emergency Response System
2. Immediate High-Quality CPR
3. Rapid Defibrillation
4. Basic/Advanced Emergency Medical Systems
5. Advanced Life Support + Post-Arrest Care

Question 8

Automated External Defibrillator (AED)

Answer 8

Analyzes the rhythm of the heart to determine if shock is indicated/necessary (during Cardiac Arrest).

Question 9

Once resuscitation is initiated, it must continue until…

Answer 9

• spontaneous circulation occurs
• spontaneous circulation and breathing occur
• another trained rescuer can take over resuscitation
• a “cease resuscitation” order is received (from a physician or other authority)

Question 10

DOA

Answer 10

Dead on Arrival

Question 11

For which two types of cardiac arrest rhythms can an AED be used to reset the activity of the heart?

Answer 11

• Ventricular Fibrillation (Fast + Irregular Heartbeat)
• Ventricular Tachycardia (Fast Heartbeat)

Question 12

Ventricular Fibrillation

Answer 12

A fast and irregular heartbeat

Question 13

Ventricular Tachycardia

Answer 13

A very fast heartbeat

Question 14

Which two types of cardiac arrest rhythms cannot be corrected with debrillation (and will result in a “no shock advised” from an AED)?

Answer 14

• Asystole
• Pulseless Electrical Activity (PEA)
