Multiple Choice

Besides 70% isopropyl alcohol, which antiseptic is commonly used where available to cleanse the venipuncture site?

The concept here is using the most effective skin antiseptic for cleansing the venipuncture site when alcohol is available and should be used as part of sterile technique. Chlorhexidine stands out because it provides rapid antimicrobial action and, importantly, leaves a persistent effect on the skin that helps keep the site cleaner during the procedure. This broad-spectrum activity is reliable for reducing skin flora and it performs well in combination with alcohol-based solutions that enhance its effectiveness, making it a preferred option where available. Povidone-iodine is effective but tends to have a slower onset and less lasting residual activity, and some clinicians prefer chlorhexidine when possible. Hydrogen peroxide is not favored for routine venipuncture because it can irritate the skin and does not offer the same persistent antimicrobial effect. Soap and water can remove dirt, but they do not provide the same antiseptic potency and residual protection as chlorhexidine, so they are not the optimal choice for preventing contamination during blood draws.
