1. case study 4: cpr and aed use

scenario: while shopping at the mall, you see an older adult collapse. they are unresponsive, not breathing, and have no detectable pulse.
after calling 911, what steps should you take before using the aed?
perform cpr for 5 minutes and then use the aed.
turn on the aed, follow the prompts, and place the pads on the persons back.
turn on the aed, follow its instructions, and place the pads on the upper right chest and lower left chest.
wait for ems to arrive before starting cpr or using the aed.

Explanation:

For the first question, in an emergency where a person is unresponsive, not breathing, and has no pulse, calling 911 (or directing someone to do so) is the first step as professional medical help is crucial. Checking for spinal injury is not the first priority when the person is in cardiac arrest. Rescue breaths without chest compressions (as in CPR) are not the first move, and abdominal thrusts are for choking, not this scenario.
For the second question, when using an AED, you turn it on, follow its instructions (it gives voice prompts), and place the pads on the upper right chest (just below the collarbone) and lower left chest (mid - axillary line). Performing CPR for 5 minutes before using an AED is not correct as AED should be used as soon as available. Placing pads on the back is incorrect. Waiting for EMS without starting CPR (if trained) or using AED is wrong as immediate action improves chances.

Answer:

1. Call 911 or direct someone nearby to call 911.
2. Turn on the AED, follow its instructions, and place the pads on the upper right chest and lower left chest.
