Final answer:
Skin impairment around an ostomy can be caused by frequent changes of the pouching system and the use of adhesive removers, both of which can lead to skin irritation and possible damage if not managed carefully.
Step-by-step explanation:
The PCT should identify that potential causes of skin impairment around an ostomy include the frequent change of the ostomy pouching system and the use of adhesive removers during appliance changes. While applying a well-fitted ostomy appliance helps protect the skin and keeping the skin around the stoma clean and dry is important for preventing irritation and infection, frequent changes can cause skin irritation due to constant removal and reapplication of the appliance. Adhesive removers, while necessary for some patients, can also irritate the skin if used excessively or if the patient has a sensitivity to the product.
