What is the recommended antiseptic for venipuncture and what alternatives exist for patients with sensitivities?

• A. No antiseptic needed.
• B. Soap and water only.
• C. Aqueous ethanol.
• D. Chlorhexidine gluconate in alcohol is preferred; alternatives include 70% isopropyl alcohol or povidone-iodine for sensitivities.

Answer: (D)

Choosing the antiseptic for venipuncture means using an agent that rapidly kills skin microbes and leaves a lasting reduction in microbial load to protect the sample and patient. Chlorhexidine gluconate in alcohol is preferred because it combines strong immediate antimicrobial action with persistent effect on the skin, which lowers the risk of contaminating the blood sample and reduces infection chances. When someone has sensitivities or allergies to chlorhexidine, the recommended alternatives are 70% isopropyl alcohol or povidone-iodine, which still provide effective antisepsis, though they may act differently in onset and duration. Using no antiseptic or soap and water alone does not provide adequate, rapid antimicrobial protection at the site for venipuncture.
