The failure to remove electrode paste residue will most likely result in:

• A. Enhanced artifact
• B. Discarded electrodes
• C. Improved detergent selection
• D. Improvement in adherence

Answer: (A)

When preparing electrodes, a clean skin-electrode interface is crucial to minimize noise. If paste residue is not removed, the contact impedance becomes inconsistent and can drift with movement, sweating, or skin changes. That unstable interface introduces more electrical noise and artifact into the recording, such as transient deflections, baseline drift, and cross-talk between channels. The other options don’t reflect what happens at the skin-electrode interface when residue remains—discarding electrodes, changing detergents, or improving adhesion aren’t direct consequences of leaving paste behind. So, not removing the paste residue most likely leads to increased artifact.
