If you haven't done any prerequisite courses yet, picking up a nursing book
would be useless because you won't have the foundation to understand what the book is saying
I would just worry about taking your nursing prerequisite courses first. You will be taking biology, anatomy & physiology 1 and 2, microbiology, and chemistry. For gen ed classes you will take college algebra, statistics, general psych, lifespan psych, speech, and some random history and humanities courses. This is just a very basic idea of the classes you will be taking before you start nursing school. But the specifics depend on the school you go to. Be prepared your sophomore year to take a pre admissions exam as part of your application to nursing school. The test will cover math, science, reading, and grammar
. There are many versions of this test, your school will choose a specific one (usually the HESI or TEAS test). If you're really looking to read up on some science stuff, pick up an Anatomy and physiology study book. That will be really helpful.
