I've been a Critical Care RN for over twenty yearsand I love to have a student to teach.
I like to have someone who is into what we are doing. They are not expected to know everything but I do expect them to try, and be enthusiastic.
I usually knowthe instructor well and will ask for another student if the one I have is not interested in learning.
I have even recrited students to work in our ICU after they graduate and it has worked out well.
As with most things, communication is the key. Let your instuctor know what you want and you are more likely to get it.
Good luck and have fun.
