An artifact that results in salt bridges is most likely caused by

• A. All of these answer choices
• B. Prepping too large of an area
• C. Allowing tape or gauze from different locations to make contact
• D. Incorrect meansuring

Answer: (A)

Salt bridges form when a conductive path links two electrode sites through moisture or electrolyte, creating an artifact that can mimic or distort the signal. If the skin prep area is too large, conductive gel or electrolyte can spread and reach neighboring electrodes, bridging them. Tape or gauze from different locations touching can also create a conductive bridge between contacts. An incorrect measuring/setup can place electrodes too closely or allow materials to contact them improperly, further enabling a bridge. Because each of these scenarios can produce the conductive connection that defines a salt bridge, all of these factors together explain why this artifact occurs. Prevent by keeping prep areas small, preventing cross-contact with tape/gauze, and ensuring proper electrode placement and impedance checks.
