<h3>What is venipuncture?</h3>
A process when blood is drawn from a vein using a needle, typically for laboratory examination. Venipuncture can also be used to treat some blood diseases by removing extra red blood cells from the blood.
The median cubital and cephalic veins are commonly used for venipuncture. The vein is punctured with a needle. The blood gathers into a tube or vial that is linked to the needle and is sealed. You take off the elastic band from your arm. After removing the needle, the area is bandaged to halt the bleeding. Pressure should be applied to a venipuncture site for at least 5 minutes.

They are able to understand what refusal means and so can try to hide things they think are wrong so as not to get into trouble.
