Final answer:
A PCT should report skin irritation and redness around the stoma option (D) to the nurse when caring for a patient with an ostomy.
Step-by-step explanation:
When caring for a patient with an ostomy, a PCT should report skin irritation and redness around the stoma option (D) to the nurse. This observation indicates that the patient may be experiencing a complication or infection at the site of the ostomy. While a healthy pink color of the stoma, minimal leakage around the ostomy appliance, and slight bleeding during appliance changes are generally normal, the presence of skin irritation and redness should be addressed by the nurse.
