A nurse is completing postmortem documentation for a client. Which of the following information should the nurse include in the documentation?

Answer: B. Location of the identification tag on the client's body

Rationale: The nurse should document the location of the identification tag on the client's body to ensure proper identification and prevent errors or mix-ups during transport or autopsy. The last set of vital signs, the copy of advance directives, and the cause of death are not part of the postmortem documentation but rather part of the medical record or death certificate.
