Question 1

Cardiac arrest may result from:&#10;A)pulseless electrical activity&#10;B)ventricular tachycardia&#10;C)ventricular fibrillation&#10;D)A,B,and C&#10;E)A and C

Accepted Answer

Cardiac arrest can result from any of the listed conditions, including pulseless electrical activity, ventricular tachycardia, and ventricular fibrillation.

Question 2

Concerning pulmonary and cardiac arrest:&#10;A)cardiac arrest may develop in the absence of respiratory arrest&#10;B)in most instances,respiratory arrest precedes cardiac arrest&#10;C)respiratory arrest may develop in the absence of cardiac arrest&#10;D)A,B,and C&#10;E)A and C

Accepted Answer

A,B,and C

Question 3

The ultimate goal of emergency cardiac care is:&#10;A)restoring normal sinoatrial rhythm&#10;B)providing cerebral resuscitation&#10;C)preventing ventricular fibrillation&#10;D)preventing atrial fibrillation

Accepted Answer

The ultimate goal of emergency cardiac care is providing cerebral resuscitation, which means restoring blood flow to the brain and preventing brain damage. While restoring normal sinus rhythm and preventing ventricular fibrillation are important steps in achieving this goal, their main purpose is to ensure proper blood flow to the brain. Preventing atrial fibrillation is not necessarily a primary goal in emergency cardiac care, as it typically does not directly impact blood flow to the brain.

Question 4

An AED:&#10;A)may be used for rapid defibrillation&#10;B)will cause premature ventricular contractions if used to shock a patient who has a normal pulse&#10;C)must be used exclusively by an allopathic or osteopathic physician&#10;D)will relieve an anginal attack

Accepted Answer

An AED (Automated External Defibrillator) is designed for rapid defibrillation in the event of sudden cardiac arrest. It is not used for treating anginal attacks or by physicians only, and it will not cause premature ventricular contractions in a patient with a normal pulse.

Question 5

BLS consists of:&#10;A)airway management&#10;B)artificial ventilation&#10;C)external chest compression&#10;D)A,B,and C&#10;E)A and C

Accepted Answer

BLS consists of airway management, artificial ventilation, and external chest compression. Therefore, the best choice is D - all of the above.

Question 6

Which of the following statements is true concerning early access and CPR?&#10;A)EMS should be notified after 1 minute of BLS in children&#10;B)EMS should be notified before the start of BLS in children&#10;C)EMS should be notified before the start of BLS in adults&#10;D)A and C&#10;E)B and C

Accepted Answer

Early access to defibrillation is critical for improving survival in cardiac arrest. EMS should be notified before the start of BLS in both children and adults to ensure that defibrillation is available as soon as possible.

Question 7

If cardiac arrest has existed for __ minutes or more,it is unlikely that the victim's CNS will be restored to its precardiac arrest state.&#10;A)2&#10;B)4&#10;C)10&#10;D)20

Accepted Answer

Research has shown that after around 10 minutes of cardiac arrest, significant brain damage usually occurs, and the chances of restoring the victim's CNS to its pre-cardiac arrest state are very low. Therefore, option C) 10 is the best choice.

Question 8

Effective chest compressions can be applied with the victim lying in the dental chair.

Accepted Answer

Effective chest compressions can be performed with the victim in a dental chair, provided the chair is reclined to a nearly flat position, simulating a firm, flat surface necessary for proper compression depth and recoil.

Question 9

Of the victims of cardiac arrest,__% do not exhibit clinical signs or symptoms before the onset of sudden death.&#10;A)10&#10;B)25&#10;C)50&#10;D)75

Accepted Answer

According to the American Heart Association, approximately 25% of victims of cardiac arrest do not exhibit any clinical signs or symptoms before the onset of sudden death.

Question 10

Which of the following is the proper sequence of the &#34;chain of survival&#34;?&#10;A)early BLS $\rightarrow$ early access $\rightarrow$ early defibrillation $\rightarrow$ early ACLS&#10;B)early ACLS $\rightarrow$ early access $\rightarrow$ early BLS $\rightarrow$ early defibrillation&#10;C)early BLS $\rightarrow$ early defibrillation $\rightarrow$ early access $\rightarrow$ early ACLS&#10;D)early defibrillation $\rightarrow$ early BLS $\rightarrow$ early ACLS $\rightarrow$ early access&#10;E)early access $\rightarrow$ early BLS $\rightarrow$ early defibrillation $\rightarrow$ early ACLS

Accepted Answer

The correct sequence for the chain of survival includes: early access (calling for help), followed by early Basic Life Support (BLS), then early defibrillation, and finally, early Advanced Cardiac Life Support (ACLS). This sequence is designed to maximize the chances of survival following a cardiac arrest.
