Yes, always report a problem to the resident's nurse. Do you know for sure that the house supervisor was relaying information to the resident's nurse or to another nurse who just happened to be standing in the hallway? And if that nurse in the hallway was supposed to tell the resident's nurse and forgot, BUT you had knowledge of the situation....well, that might not lead to a great outcome. It becomes a game of "psssst, pass it on". And trust me, that is never a good game to play because rarely does the message come through.
