Final answer:
A nurse aide should report a client's grievances to the nurse in charge, who is directly responsible for managing the client's care.
Step-by-step explanation:
When a nurse aide is assisting a client in resolving grievances, the correct person to report the grievance to is generally the nurse in charge. This is the individual who has immediate responsibility for the ongoing management of the client's care and can address concerns directly or escalate them to the appropriate party. Reporting to the primary health care provider, family, or administrator may be necessary depending on the situation, but the first point of contact should be the nurse in charge. It's important to follow the facility's policies and procedures for handling grievances.
