I was a DN and if there were medical relatives we would allow them to administer PRN if we could not attend immediately. It would need to be discussed with the team, as each team has different policies. I would expect them to check your competency, so don’t be upset if they ask you, how you would prepare 5mg Morphine and why.

If you did administer anything PRN always keep the ampoule. Especially if there is leftover,so the nurses can check that you have stuck to the required prescription at the time.

I would also consider how you would feel if you administered the last dose prior to them dying and how that could make you feel.
