Honestly there are those days when you don't feel you have ANYTHING together as a nurse LOL
One of the first times it really sunk in for me, was when some called "Nurse can you help me?" and yes, I am a nurse and can help you

Even a student nurse is still a nurse. You will have days when it seems like you know nothing and then you will have days that are "Yes, I know stuff"
Your practicum experiences should help you get a feel for the different places where you can work - basically acute care or extended.
Personally I am an acute care person along with my Palliative/Hospice area. I would ultimately want to specialize in Palliative Care as I truly love working there.
All the best in your continued studies and I look forward to hearing how you are doing.
Yours in nursing
