Question 9: Jessica goes to the gym locker room after completing her workout and finds a woman lying on the ground. After she checks the scene for safety, she checks for responsiveness, breathing, and bleeding. The woman does not appear to be conscious or breathing, and Jessica cannot feel her pulse. Jessica calls 911 and places the woman on her back. Jessica is not CPR-certified. What is the next step the 911 operator should direct Jessica to take?

Immediately initiate chest compressions while calling for help
Deliver a cycle of 100 chest compressions before checking for signs of life
Find and attach an automated external defibrillator (AED) (Correct answer)
Conduct a blind swipe of the mouth to remove any possible foreign objects

Correct answer: Find and attach an automated external defibrillator (AED)

Explanation: The first step a person should take when encountering a scenario like this is to call 911 and follow the dispatcher's instructions. Usually, the second step is to find an AED as it can help to guide a trained or untrained person through CPR, monitor vital signs, and administer shocks if necessary. In this situation, After checking for responsiveness, breathing, and pulse and calling 911, Jessica would most likely be guided by the operator through the use of an AED. AEDs are intended to be usable by anyone, even if the individual is not CPR-certified. The American Heart Association recommends that an untrained person administer hands-on CPR. Hands-only CPR consists of chest compressions delivered at a rate of 100 beats per minute and a depth of two inches. Blind swipes of the mouth to remove foreign objects are no longer encouraged due to the risks for further lodging the object into the airway. Conventional CPR consists of giving two breaths after every 30 compressions.
