I need some help regarding a situation in which another RN medicated my patient without documenting. This patient was seeking medication when I came to see them, and it had been well enough time before they were allowed medication (according to the computer documentation), so I administered the med. The other RN came by later on to inform me that they were going to chart on this medication that they gave earlier and noticed that I gave the med just a little while ago (and had never told me they gave it.) Now, this makes it seem as if I gave the medication too early after the other RN had done so because this person is able to adjust the time in the computer when they document. Best advice?
