As one VERY new FNP to a soon-to-be new FNP, I will say that A LOT of my learning specifically related to clinical practice happened while studying for boards. Plan to commit a lot of time, attention, and energy to your board prep--partly because you want to pass the first time, and partly because this is your last big push/opportunity to learn before entering practice. No joke, I learned probably as much if not more studying for boards than I did in my entire MSN program.

Also, I second someone else's advice about guidelines. So many disease processes have clinical guidelines or protocols to follow. Get to know your resources and be comfortable accessing them. Don't know which antibiotic to prescribe for your patient with pneumonia? Not a problem, because there are guidelines. Not sure which vaccines happen when? See the vaccine schedule. Not sure if your patient needs to be screened for lung cancer? There's a guideline. Not sure which hypertensive med to start? Guideline. You don't have to have them all memorized right out of the gate (though you will learn a lot studying for boards). Just know that there is probably a guideline, and know where to find it.
