Final answer:
A Practical Nurse (PN) can be delegated the task of providing stoma care for a client with a well-functioning stoma, whereas assessing new ileostomies and complicated colostomies are typically tasks for Registered Nurses.
Step-by-step explanation:
The task that can be safely delegated to a Practical Nurse (PN) would be to provide stoma care for a client with a well-functioning stoma. Assessing the function of a newly created ileostomy or caring for a client with a recent complicated double barrel colostomy are both tasks that typically require the more advanced skills of a Registered Nurse (RN), who has the training to perform assessments and manage complex situations. The PN is capable of performing routine care and monitoring of a stable stoma, ensuring the skin integrity around the stoma, changing the appliance, and teaching the patient stoma care techniques.
