First semesters are always a little unpredictable. My suggestion would be to learn normal vital signs for adults, and for peds/infants. I have a clipboard that I bought at the campus bookstore that has normal ranges for vitals, ABGs, growth charts, abbreviations, etc. It was 22 dollars I think, but it was SOOOO worth it. It also has a big calculator on the clip which I used to adding volumes, and doing quick dosage calculations. After a while, I didnt have to look at the chart anymore, they were just stuck in my head
I know they sell them online somewhere if your bookstore doesnt have them. If you need help finding one, if you are interested in getting one, let me know, and I will find one online for you, (or anyone else interested).
SKIM the books ahead of time if you want, but if you are anything like me, if I read really far in advance, I wont remember the material for the test. School is stressful enough, but it you manage your time effectively it decreases it, it doesnt eliminate your stress by any means, but atleast you wont be pulling your hair out on a daily basis
