In the context of the integumentary system, what should be placed over the skin before applying a grounding pad electrode during an electrotherapy procedure?

• A. A dry gauze pad
• B. A layer of talcum powder
• C. A conductive gel
• D. An adhesive bandage

Answer: (C)

Verified step by step guidance

1. Understand the purpose of the grounding pad electrode in electrotherapy: It is used to safely conduct electrical currents through the skin to prevent burns or uneven current distribution.
2. Review the properties of the skin in the integumentary system: The skin acts as a barrier and has variable conductivity depending on its moisture and surface preparation.
3. Analyze the options provided: Dry gauze pad, talcum powder, conductive gel, and adhesive bandage. Consider their ability to enhance electrical conductivity.
4. Recognize that conductive gel is specifically designed to improve electrical contact between the electrode and the skin by reducing resistance and ensuring even current distribution.
5. Conclude that applying a conductive gel over the skin before placing the grounding pad electrode is the correct choice to ensure safety and effectiveness during the electrotherapy procedure.
