New York State Emergency Medical Technician (EMT) Practice Exam

What is the best course of action when an AED pad must be placed over a medication patch?

1. Apply the AED pad at least 1" away from the medication patch

2. Continue CPR until the name of the medication is determined

3. Move the patch to another area of the chest

4. Remove the medication patch and apply the AED pads

The correct answer is: Remove the medication patch and apply the AED pads

When dealing with an Automated External Defibrillator (AED) in a situation where there is a medication patch, the safest and best practice is to remove the medication patch and then apply the AED pads. This is because medication patches, such as those used for nitroglycerin, hormone therapy, or fentanyl, can cause skin burns or other adverse effects if the AED delivers a shock while the patch is still in place. The electrical current from the AED could potentially cause the medication from the patch to be released into the body more rapidly or could interfere with the AED's function. The action of removing the patch ensures that there are no barriers or risks associated with the medication. After removal, placing the AED pads on clean skin is critical for ensuring the effectiveness of the shock and minimizing the risk of any skin irritation or burns. In emergency situations, the priority is to ensure the patient's safety and the effectiveness of the defibrillation, making this course of action essential for appropriate care. Other options may not adequately address the risks related to the medication patch, as continuing CPR without managing the patch or simply placing the AED pads around it can leave the patient at risk for complications.
