What is the correct sequence to properly end a venipuncture?

The correct sequence to properly end a venipuncture is essential for both the safety and comfort of the patient, as well as for effective specimen collection.

Releasing the tourniquet first is critical as it alleviates pressure on the vein, allowing blood flow to return to normal before the needle is removed. Following this step, removing the tube comes next; this not only ensures that the specimen is collected properly but also prevents any backflow of blood into the vacuum tube. After the tube is removed, the next step is to withdraw the needle from the vein while maintaining pressure over the puncture site to minimize bleeding.

Applying a cotton ball before bandaging is important because it helps to absorb any residual bleeding and maintains cleanliness of the site. Finally, placing a safety cap on the needle ensures that it is disposed of correctly to prevent needle-stick injuries, contributing to a safe environment for both the healthcare worker and the patient.

This sequence aligns with best practices in phlebotomy to ensure that the procedure is completed efficiently and safely.
