Answer: A. Sterile gloves must be worn during the procedure. 

Currently, research is insufficient to support routine use of sterile gloves during implanted port accessing and deaccessing procedures. Refer to the Access Device Standards of Practice for Oncology Nursing for more information.   

Answer B is recommended because it is important to palpate the area around the port for warmth and tenderness and to determine the orientation of the port prior to access.   

Answer C is recommended because ensuring adequate blood return prior to use of the port can help reduce the incidence of infiltration and indicate proper needle insertion.  

Answer D is recommended because use of a noncoring needle separates the silicone septum of the port during accessing and prevents coring the material, which could lead to debris in the port reservoir and leakage.
