While class work is important, I think there is more to an application than what you have learned in a class.
I personally have attended and completed classes in
Chem. I, II (with lab)
Physics (non calculus) I,II (with lab)
Genetics, Immunology, (audits)
Molecular cell biology
Healthcare related special topic classes like parasites and Aids directed study
More computer science than necessary, part of a degree
I finished out my undergrad degree with greater than 200 credit hours.
but where I think it is more important to shine, is to make yourself unique. I have said it before, and i will say it again.
Get an ACLS instructor or PALS instructor cert. Obtain your CCRN, and or another national certification say the CPAN.
Go out of your way to learn new skills, I learned to place PICC's specifically because I knew that it would look good to have central line experience on my resume. Teach mini lectures on your unit, on specific ICU related topics.
Participate in research, I wrote a review article while in nursing school
that was published. That alone was highly looked on by my interviewers.
Do well on your GRE, My advice is, take the test once, you might surprise yourself, I did no prep for it and did well, thus saving myself the money a review would have cost.
Get a variety of ICU experience, I worked in two different ICU's, one was a cardiac intensive care, and the other a trauma surgical burn intensive care. The variety of experience is a big bonus. Plus the cardiac ICU work made the CCRN a cinch.
Learn about your program of choice before going there for the interview. This will help you ask more direct questions that will make the interviewers remember you.
Take on the role of charge in your unit. This will show that you have an inherent ability to lead, and to take charge of situations that are difficult. this is pretty much the reason I was willing to accept the permanent charge position in my ICU.
I hope this helps.
let me know if you want more specific info. I will be glad to give you my opinion.
