Excitement and nervousness are to be encouraged.
The excitement typically drives interest and study. An appropriate level of nervousness encourages caution and commitment to doing the right thing for the patient. Without either of those two emotions present, you're looking at possible disaster.
As far as "not knowing" what nursing is and therefore being nervous (as a PP indicated), that's a dangerously ignorant opinion of the field. There is plenty to be wary of, especially when you're new and may not know enough to know better. A healthy dose of caution is invaluable.
Yes, you will adjust to the level of responsibility placed on you, but it is both important and normal for nurses--especially new ones--to experience some anxiety throughout school and well into their first years of employment as they adjust to a rapidly-changing, brand-new environment that often depends on them to keep it safe and functioning.
Best of luck in your studies! You sound like you'll make a great nurse!
