The function of alcohol in the cleansing process before venipuncture is to disinfect the site. When preparing the skin for a needle stick, it is essential to minimize the risk of infection. Alcohol solutions, specifically isopropyl alcohol, are effective disinfectants that kill bacteria and other pathogens on the skin's surface. This process helps ensure that any microorganisms that could lead to infection are eliminated before the procedure, thus promoting a safer environment for both the patient and healthcare provider.

Using alcohol effectively reduces the microbial load and prepares the area for a clean and sterile venipuncture. The antiseptic properties of alcohol are critical in maintaining hygiene standards in medical procedures and assuring patient safety.
