What should be done to the skin before placing leads or electrodes?

• A. Wash with soap and water
• B. Clean with alcohol
• C. Use adhesive tape
• D. Moisturize the skin

Answer: (B)

Cleaning the skin with alcohol before placing leads or electrodes is important because it effectively removes oils, dirt, and dead skin cells that could interfere with the electrical connection of the leads. Alcohol also has antiseptic properties that help reduce the risk of infection at the site where the electrodes will be placed. This thorough cleaning ensures that the electrodes adhere well to the skin and that the electrical signals can be transmitted accurately, which is crucial for effective monitoring and assessment. Other methods, such as washing with soap and water, while helpful in general hygiene, may leave residues that could interfere with the electrode function unless fully dried. Using adhesive tape is not relevant in this context, as the primary concern is ensuring a clean surface. Additionally, moisturizing the skin can actually hinder the adhesion of electrodes and impede signal transmission, as it can create a barrier between the skin and the electrode. Therefore, using alcohol for cleaning is the most effective approach prior to electrode placement.
