Final answer:
It is false that alcohol does not need to dry before performing a ventipuncture; the alcohol must dry completely to prevent discomfort and ensure accurate test results.
Step-by-step explanation:
False, before performing a ventipuncture, it is essential that the alcohol used to cleanse the site has dried completely. The presence of wet alcohol at the puncture site can cause several problems. It may cause discomfort or a stinging sensation for the patient when the needle is inserted, as the alcohol can enter the puncture made by the needle. More importantly, wet alcohol can also hemolyze or break down the blood cells, potentially leading to inaccurate test results. Therefore, it is crucial to allow the skin to air dry after the application of alcohol before proceeding with the ventipuncture.
