Which cleansing agent is indicated for skin preparation in this material?

• A. Betadine/Iodine
• B. Alcohol
• C. Hydrogen peroxide
• D. Water

Answer: (A)

Skin preparation requires an antiseptic with broad-spectrum antimicrobial activity that remains on the skin long enough to reduce microbes during the procedure. Povidone-iodine (Betadine) provides strong coverage against bacteria, viruses, and fungi and has residual activity on the skin, making it the suitable cleansing agent for this context. Alcohol acts quickly but lacks lasting effect when used alone, hydrogen peroxide can be irritating and is not ideal for routine skin prep, and water alone does not disinfect. Therefore, Betadine/iodine is indicated.
