Final answer:
Aseptic techniques should be used when changing dressing site option D is correct answer.
Step-by-step explanation:
The correct answer would be option d: Aseptic techniques should be used when changing dressing site. Aseptic technique is extremely important in postoperative peritoneal catheter exit-site care to prevent infections. It involves taking precautions to avoid introducing microbes to the patient's body during the dressing change.
This includes using sterile water to rinse the exit-site and ensuring that only trained staff change the dressings to minimize the risk of contamination. Immobilizing the catheter is also important to prevent accidents or damage to the site. Therefore, option d would not be correct in this case.
