Which technique should be avoided when preparing a venipuncture site?

1. Using an alcohol swab.

2. Wiping the site with iodine.

3. Applying too much pressure while cleaning.

4. Allowing the site to dry completely.

The correct answer is: Applying too much pressure while cleaning.

Applying too much pressure while cleaning a venipuncture site can cause issues that may impact the procedure's success. When preparing the skin, the goal is to cleanse the area effectively without causing trauma to the skin. Excessive pressure might make the skin fragile or irritate it, potentially leading to discomfort for the patient and complicating the procedure. Proper skin preparation aims to minimize the risk of infection and ensure a successful draw from the vein. Techniques such as using an alcohol swab or iodine are accepted practices for disinfection and should be done carefully to ensure they are effective. Allowing the site to dry completely after cleaning is also important, as it allows the antiseptic to act and minimizes the risk of contamination during the venipuncture process. Thus, avoiding excessive pressure is critical to maintaining skin integrity and promoting a successful venipuncture outcome.
