Working in the urgent care..

I am an urgent care nurse.. a new graduate and sometimes i feel like everything is still kinda new or I feel like I dont know certain things when i feel like im supposed to know these things?? Does anyone ever feel that way?? Like I know the Urgent care is almost like a mini ER so to say, so sometimes I feel sooo overwhlemed cause theres soo many things to know.. such as immunizations, all the other medications like antibiotics etccc.. putting on casts.. its just stressful sometimes cause its alot to take in as a new grad.

It definitely is alot different than the hospital, I can say that.
