Venipuncture is a medical procedure used to access a vein for various purposes, such as drawing blood or administering medications. It typically involves using a sterile needle to puncture the skin and enter a vein, usually in the arm. This procedure is commonly performed by healthcare professionals, including nurses and phlebotomists. The process begins with cleaning the area to prevent infection, followed by the insertion of the needle. Once the blood is collected or the medication is delivered, the needle is removed, and pressure is applied to the site to stop any bleeding. Proper technique is essential for patient safety and comfort.
