Final answer:
A nurse aide should report patient concerns to the nurse supervisor, who is in charge of patient care and delegating tasks to the nursing staff.
Step-by-step explanation:
The nurse aide should report a client's concerns directly to the nurse supervisor. It is part of the standard medical protocol that a nursing aide works under the direct supervision of a registered nurse, and their role includes monitoring patients and reporting significant information to the supervising nurse. The nurse supervisor is responsible for assessing the situation and taking the necessary action, whether it involves providing immediate care or relaying the information to the primary health care provider. As a nurse aide, the focus is often on providing specific treatments like dialysis and ensuring the process is conducted safely and effectively, which includes reporting any patient's concerns related to their treatment or condition. While the nurse supervisor is often the first point of contact, the primary health care provider might be contacted subsequently if the issue requires their involvement.
