When performing a central venous catheter dressing change,which of the following steps is correct?

A) Wear sterile gloves while removing and discarding the soiled dressing.
B) Apply pressure on the catheter-hub junction when removing the soiled dressing.
C) Place a sterile transparent dressing over the site and the catheter-hub junction.
D) Have the patient wear a mask or turn his head away from the site.

Aseptic technique should be used when approaching the insertion site.Therefore,both nurse and patient should wear a mask.If the patient cannot wear a mask,have him turn his head away from the insertion site during the procedure.Sterile gloves should be worn when placing the new sterile dressing; however,procedure gloves are used to remove the soiled dressing.The nurse should stabilize the catheter while removing the soiled dressing,but not apply pressure to the catheter-hub junction.The transparent dressing should cover the hub of the catheter,but not the catheter-hub junction; this makes it too difficult to remove without disturbing the integrity of the IV line or the site.
