Which is a correct practice for preparing a venipuncture site?

Cleaning with an antiseptic swab and allowing it to dry is the correct practice for preparing a venipuncture site because it effectively reduces the risk of infection at the site of the blood draw. The application of an antiseptic solution, such as alcohol or iodine, helps to eliminate bacteria and other microorganisms on the skin. Allowing the antiseptic to dry is crucial because it ensures maximum efficacy by forming a protective layer that further prevents contamination during the procedure.

Proper site preparation is vital in phlebotomy to safeguard the patient's health and maintain the integrity of the blood sample being collected. This practice aligns with infection control protocols and best practices in medical procedures. Other methods, such as excessive wiping, would not only be ineffective but could introduce more bacteria or irritate the skin. Using non-sterile gloves does not maintain the necessary sterile environment, and applying pressure to the site is relevant post-venipuncture rather than during the preparation phase.
