OFA CPR Techniques & Automated External Defibrillation (AED) 5

Question 1

Which of the following signs indicates that CPR is being performed effectively?

Accepted Answer

A palpable pulse can be felt in the carotid artery during compressions

Answer

A palpable carotid or femoral pulse during compressions indicates that blood is being circulated effectively by the rescuer.

Question 2

An AED is applied to a worker in cardiac arrest near a metal scaffolding. What precaution must the rescuer take?

Accepted Answer

Ensure no one is touching the patient when the shock is delivered

Answer

Everyone must stand clear and avoid touching the patient at the moment of shock delivery to prevent inadvertent current transfer.

Question 3

In occupational first aid, when should CPR be stopped?

Accepted Answer

When the patient shows signs of life, EMS takes over, a physician orders cessation, or the rescuer is physically unable to continue

Answer

CPR should continue until one of these endpoints is met: return of spontaneous circulation, transfer of care to EMS, medical directive to stop, or physical exhaustion of all rescuers.

Question 4

During CPR, how long should a rescuer take to check for a pulse?

Accepted Answer

No more than 10 seconds

Answer

A pulse check should take no more than 10 seconds; if a pulse is not definitely felt, compressions should resume immediately.

Question 5

A worker in cardiac arrest is soaked from working in the rain. What must the rescuer do before using the AED?

Accepted Answer

Dry the worker's chest before attaching the pads

Answer

A wet chest can prevent pad adhesion and conduct electricity to bystanders; quickly drying the chest before pad placement is essential.
