EXAM QUESTIONS
Q1.
When should the rescuer initially ensure that the scene is safe?
a. When the rescuer first sees a potential victim
b. After the rescuer activates the emergency response system
c. As emergency medical services arrive on the scene
d. After an AED that is attached to the victim delivers a shock
, CORRECT ANSWER
A
RATIONALE
The rescuer initially ensures the scene is safe to prevent further injury or harm to both the
potential victim and themselves by assessing potential hazards, such as electrical shock or
structural instability. This step is crucial because it allows the rescuer to take control of the
situation and mitigate risks before proceeding with any further actions.
Q2.
As soon as an AED becomes available, which of the following is the first step the
rescuer should perform to operate the AED?
a. Place the AED pads on the chest
b. Deliver 2 rescue breaths before using the AED
c. Turn on the AED
d. Complete 5 cycles of chest compressions
CORRECT ANSWER
C
RATIONALE
The correct answer is "c. Turn on the AED" because the AED (Automated External
Defibrillator) will not function correctly until it is turned on, allowing it to analyze the
victim's heart rhythm and provide appropriate instructions. Turning on the AED at the start
is essential to initiate the rescue process and ensure the device is functioning properly.
Q3.
After the AED delivers a shock, the rescuer should
a. Wait for the AED to reanalyze the rhythm
b. Immediately restart CPR, beginning with chest compressions
,c. Provide 2 ventilations to the victim
d. Immediately check the carotid pulse for no more than 10 seconds
CORRECT ANSWER
B
RATIONALE
The correct answer is "b. Immediately restart CPR, beginning with chest compressions"
because after the AED delivers a shock, the priority is to restore blood flow to the brain and
heart by restarting CPR, which involves compressions to maintain circulation. This action is
crucial to maintain the effectiveness of the AED's treatment and increases the chances of
successful resuscitation.
Q4.
The 2010 AHA Guidelines for CPR and ECC recommend that to identify cardiac arrest in
an unresponsive victim with no breathing (or no normal breathing), a healthcare
provider should check a pulse for no more than
a. 25 seconds
b. 10 seconds
c. 15 seconds
d. 20 seconds
CORRECT ANSWER
B
RATIONALE
The American Heart Association (AHA) Guidelines emphasize the importance of quickly
identifying cardiac arrest, and a 10-second pulse check allows healthcare providers to act
swiftly and initiate life-saving interventions in a timely manner. This short time frame also
, minimizes the likelihood of a false assessment, ensuring that the correct treatment is
administered promptly.
Q5.
After you identify an unresponsive victim with no breathing (or no normal breathing)
and no pulse, chest compressions should be initiated within
a. 25 seconds
b. 10 seconds
c. 30 seconds
d. 60 seconds
CORRECT ANSWER
B
RATIONALE
The correct answer is based on the American Heart Association (AHA) guidelines, which
emphasize the importance of starting CPR promptly to maximize the chances of a
successful outcome, and a delay of 30 seconds or more can significantly decrease the
likelihood of survival.
By initiating chest compressions within 30 seconds, rescuers can minimize the time the
victim is without blood circulation and oxygenation, thereby increasing the chances of
successful resuscitation and ultimately improving the victim's chances of survival.
Q6.
Which of the following victims need CPR?
a. A victim with a pulse and who is having trouble breathing
b. A victim with chest pain and indigestion
c. A victim who is unresponsive, no normal breathing and absent/ inadequate pulse
d. A victim who is unresponsive but is breathing adequately
