Final answer:
Remove the medication patch, clean the area to remove any residue, then apply the AED pads and continue with CPR following the correct guidelines.
Step-by-step explanation:
When applying an Automated External Defibrillator (AED) and noticing a medication patch in the area where an AED pad should be placed, you should remove the medication patch, wipe away any residue, and then apply the AED pads. This is because the electrical charge delivered by the AED can cause the medication from the patch to enter the skin at a high rate, potentially causing burns or introducing an unsafe dose of medication. CPR should be continued as per guidelines, with compressions of at least 5 cm deep at a rate of 100 compressions per minute, until the patient shows signs of recovery or an experienced healthcare professional takes over.
