A nurse enters a client's room to perform a focused assessment. Which of the following client information should the nurse use to properly identify the client?

A. Patient’s name: The client’s name is the most reliable and direct way to identify a client. It should be verified using two identifiers (e.g., name and date of birth) to ensure the correct client is receiving care. B. Room number: While room numbers are helpful in identifying a location, they should not be used as the primary method for client identification. Two clients could be in the same room, so room number alone is not sufficient. C. Telephone number: A client’s telephone number is not an appropriate identifier for performing a focused assessment, as it is not unique to the patient’s identity in a healthcare setting. D. Diagnosis: The diagnosis is important for the care plan but should not be used to identify the client. Multiple clients may have the same diagnosis, so it cannot serve as a unique identifier.
