MOSBY!!!!!!!!!! I have both and Lipincott. I'm gonna tell you. I thought Mosby was written simple, Saunders was in detail but Lipincott has DISORDERS! So they all in a sense helped as far as knowledge. The test was written as MOSBY! Some of the same questions where in Mosby word from word. I PROMISE! There was TONS of priority, infection control-I swear I had @ least 60 questions! Only 3 math problems, 40 pharm. & the rest general questions. I was not sure which NCLEX to use, I had brought so many books. My whole family is mostly in the medical field. My mom told me to stop buying books. I spent @ least a grand on books to prepare. They helped me, they did. I started sorting threw ALL my books & came across an older Mosby I had purchased THREE years ago. I had @ least 25 or 23 questions came out of Mosby. Not Saunders or Lipincott. I was soooooooo shock that the NCLEX was basic. I was expecting a monster how people speak of it. Someone @ this site had gave the BEST advice EVER about the NCLEX. I kept repeating it in my head along with other things. They said approach the test as if it is just another practice exam. It helped. The test was worded simple. The test was broad as people say it is. The people @ the center are very professional, kind & prompt with all your needs & concerns. Everyone testing has positive energy, most where in sweats, very causal. 2 hours in, the NCLEX gives you an option for a break. It's a plus when you're expecting more and it's less. I only had 4 lab val. questions. You'll do fine, Good Luck & congrats on your new profession.
