Release tourniquet, remove tube, withdraw needle

The correct sequence for withdrawing a needle after drawing blood is to first release the tourniquet, then remove the tube, and finally withdraw the needle.

Releasing the tourniquet first allows venous pressure to normalize and helps reduce the risk of hematoma formation by preventing pooling of blood in the vein once the needle is removed. Following this, removing the tube helps to seal the site where the blood was drawn and minimizes exposure to blood. Finally, withdrawing the needle carefully ensures that the puncture site is closed without causing unnecessary trauma to the surrounding tissue.

This sequence is critical in practice to ensure patient safety and comfort, along with maintaining proper technique to minimize complications.
