Final answer:
A nursing assistant must be aware of their job description and is responsible for tasks such as patient care under the supervision of a nurse. They should speak up regarding concerns for safety or if a task is outside their scope, and they cannot make decisions on patient care or administer drugs.
Step-by-step explanation:
As a nursing assistant, you must know what tasks are in your job description. Your role is to provide support under the direct supervision of a registered nurse, focusing on tasks such as dialysis treatments, patient history review, vital signs recording, and ensuring sterile procedures. While you may be delegated tasks, it's imperative to speak up immediately if you have concerns about a task's safety or if it's outside your scope of practice.
Additionally, making decisions about a person's care or administering drugs typically exceeds a nursing assistant's responsibilities. Knowing your limitations and the ability to refuse tasks for valid concerns, like safety, is part of professional practice.
