Step 10: Attach the butterfly needle and tubing to the syringe with the factor

Guidelines:

• Use a #23 or #25 butterfly needle.
• Remove the butterfly needle from the package.  Straighten the tubing.  Loosen but do not remove the cap.
• Do not touch the tip of the syringe or the end of the tubing.  If you touch the tip of the tubing, get a new one.
