Asking the assist personnel to document the client's time of death is not correct. While accurate documentation of the time of death is important, the responsibility typically falls on the healthcare provider or physician who confirms the death, not necessarily the assist personnel involved in postmortem care.

Place an identification tag on the outside of the client's shroud is correct. This action ensures proper identification throughout the postmortem process and aligns with standard procedures for maintaining identification integrity during autopsy procedures. Identifying the client accurately is crucial to prevent any errors or mix-ups.

Wearing sterile gloves when cleaning the client's body is incorrect. Sterile gloves are not typically required for postmortem care. While gloves are important for infection control, they don't necessarily need to be sterile for handling deceased patients unless there are specific infectious concerns.

Removing the client's dentures and give them to the client's family is incorrect. In most cases, the client's personal belongings, including dentures, are typically handled according to specific protocols or the family's wishes. However, removing the dentures and giving them to the family isn't typically part of postmortem care. The family might be informed about the presence of dentures and their disposition, but the decision to give them to the family should follow established procedures or the family's preferences.
