Final answer:
The nurse is correctly using the Right Task of delegation in this scenario.
Step-by-step explanation:
The nurse is correctly using the Right Task of delegation. The task of assisting with oral hygiene does not require decisions based on the nursing process, so it can be appropriately delegated to the nursing unlicensed assistive personnel (UAP).
The other rights of delegation include: Right Circumstances - which ensures that the task can be safely and effectively delegated in the current situation, Right Person - which involves selecting the most appropriate person to delegate the task to, Right Direction/Communication - which involves providing clear and concise instructions and expectations, and Right Supervision - which ensures that the UAP is adequately supervised and supported during the task.
