Which product is 70% alcohol/chlorhexidine gluconate?

Which product is 70% alcohol/chlorhexidine gluconate?

• A. ChloraPrep
• B. Betadine
• C. DuraPrep
• D. Hibiclens

Answer: (A)

Understanding which skin prep products pair alcohol with chlorhexidine gluconate and what their concentrations are helps identify the correct choice. A solution that combines chlorhexidine gluconate with 70% alcohol provides rapid kill from the alcohol and persistent antimicrobial activity from the CHG. The product that matches this combination is ChloraPrep, which contains chlorhexidine gluconate 2% in 70% isopropyl alcohol. DuraPrep, by contrast, uses an iodine-based antiseptic in alcohol, not chlorhexidine. Hibiclens is chlorhexidine gluconate but in an aqueous (non-alcohol) solution, so it lacks the alcohol component. Betadine is povidone-iodine, not chlorhexidine.
