First semester is very general and clinically you basically only help the patient with ADLs and maybe your professor will want you to interview the patient. No medication administration at least at my school, and we only had to write one nurse's note that semester.
The questions on the test are a little different than how they were in the prerequisite classes so for me that was what drove my A average to B- the first semester. Its not straight knowledge question, they give you a scenario and you have to pick the correct action to take. So for example they will never ask you what is the normal range of serum potassium (3.5 - 5.0), they might give you a serum potassium of 3.2 and then give you a list of food, now you have to pick the food or drink to offer the patient that has a lot of potassium (orange juice, banana, etc). It's weird at first but you'll get used to it eventually. And memorize your medical terminology
, the questions usually don't use layman's terms, like it won't say the patient is sweating, it'll say the patient is diaphoretic.
The nursing books
have a lot of Anatomy and physiology information, don't spend too much time on that, i would use that only as a reference if you don't understand something, but there won't be any questions on A&P.
If i could start nursing school all over again, i'd buy NCLEX review lectures right away (kaplan, feuer, hurst or drexel). Its really a condensed form of the lectures you'll get in nursing school so only the most important stuff is presented. They really give you a good base especially when you start getting into pathophysiology.
