Describe how you apply the tourniquet in performing a blood draw.

First tell the patient where your going to apply the tourniquet. Then you take both your right and left hand and stretch the tourniquet as far as you can but make it as comfortable to the patient and on the back of the arm. Then your going to cross the tourniquet like a shoe string. Have it crossed and then take your dominant hand and make a loop with the string under the cross and then just leave it as so. Then you start your IV and draw your blood. Then when your done you can quickly release it by pulling the string that is left out from the loop and done!

If you don't understand it I'm extremely sorry!
