So you are first year student nurse.
You have plenty of time to learn all your proficiencies as not expected to learn everything in a matter of weeks of starting your course.
Hopefully when you are on your placement you'll pick up more information about the things you are asking about by asking your placement supervisor and speaking with the qualified nurses.
Agree with what the person said in post 4 to you.
Do more research on the information you are asking about as should be helpful for you.
