Final answer:
Nursing assistants work under the direct supervision of a registered nurse and are responsible for tasks like reviewing patient history and monitoring dialysis processes, but they do not independently make care decisions or administer medication unless properly authorized.
Step-by-step explanation:
As a nursing assistant, you do not make decisions about a person's care independently. Instead, you work under the direct supervision of a registered nurse. The typical duties focus on providing support tasks such as reviewing patient history, assessing and responding to patient needs before and during treatment, and monitoring the dialysis process. Specifically, for dialysis treatments, this includes taking and reporting a patient's vital signs and preparing solutions and equipment to ensure accurate and sterile procedures. Nursing assistants must perform all tasks as directed by the nurse and need a written job description before employment. It is not within a nursing assistant's scope of practice to give drugs even if directed by a nurse except under certain conditions and with appropriate training and credentials.
