BLS Recognition of Cardiac Arrest 3

Question 1

You witness a man collapse and suspect cardiac arrest. You are alone with your phone. In what ORDER should you act?

Accepted Answer

Shout for help, call 911, start CPR

Answer

For a witnessed adult cardiac arrest, the priority sequence is: confirm unresponsiveness, shout for help, call 911 (or have someone call), then begin CPR.

Question 2

A patient is found unresponsive with slow, gurgling breaths about every 10 seconds. How should you categorize this breathing?

Accepted Answer

Abnormal — treat as cardiac arrest

Answer

Slow, gasping, or gurgling breaths are classified as abnormal (agonal) breathing; the victim should be treated as being in cardiac arrest.

Question 3

Which pulse site is preferred when checking for a pulse in an unresponsive infant?

Accepted Answer

Brachial artery

Answer

The brachial artery on the inner upper arm is the preferred pulse check site for infants because the neck is short and the carotid can be difficult to locate.

Question 4

A person is found slumped in a chair, unresponsive, with no visible breathing. An AED is 2 minutes away. What should the first responder do FIRST?

Accepted Answer

Move the victim to a flat surface, then call for the AED

Answer

The victim should be placed on a firm, flat surface (which also confirms position for effective compressions) while the AED is retrieved, and CPR should begin immediately.

Question 5

Which statement about ventricular fibrillation (VF) as a cause of cardiac arrest is CORRECT?

Accepted Answer

VF is the most common initial rhythm in sudden adult cardiac arrest

Answer

Ventricular fibrillation is the most common initial rhythm seen in witnessed sudden cardiac arrest in adults and is the primary indication for defibrillation.
