What is the primary purpose of using an alcohol prep pad before ECG electrode placement?

To provide comfort to the patient
To ensure better adhesion of electrodes
To clean the electrodes themselves
To add a cooling effect to the skin

The correct answer is: To ensure better adhesion of electrodes

The primary purpose of using an alcohol prep pad before the placement of ECG electrodes is to ensure better adhesion of the electrodes. Cleaning the skin with an alcohol pad removes oils, dirt, and other contaminants that can interfere with the electrode's ability to adhere to the skin. This is essential for obtaining a clear and accurate ECG signal, as good electrode contact is necessary for effective electrical conduction. When the skin is clean and free from impurities, the adhesive properties of the electrodes are enhanced, leading to better signal quality and reducing the chances of motion artifacts during the ECG recording. High-quality adhesion is crucial because if the electrodes do not stick well, they may shift or detach, which can compromise the accuracy of the ECG results. Therefore, using an alcohol prep pad is a standard practice to optimize electrode performance and the overall success of the ECG procedure.
