I will add my two cents, since I just passed the NLN Nutrition exam! :) I prepared for two weeks by reading a "Nutrition for Healthcare Providers" book and listening to some lectures through iTunesU. I also ordered the practice test from the NLN website, only to find out that the exact questions were posted on a flashcard website. It's easy to find if you Google it, but be advised, there are some mistakes on the flashcards (2-3 questions have the wrong answer, if you're studying hard enough, they're pretty obvious). To be sure you found the right flashcards, the first question is about a baby with failure to thrive. The test itself was harder than I expected. There were a decent amount of questions that were not covered in my book and caught me off guard. Some of the questions were also pretty subjective or did not give enough information in my opinion. I wasn't feeling great about it, but I clicked "Submit for Grading" and crossed my fingers. My grade came up as a percentage and did not have a clear Pass or Fail. Apperantly the school determines what is a passing grade and my school didn't have any idea, so it took a day to get that information, but good news was delivered today and I passed. Since I could not find it, I will also post number of questions for the NLN Nutrition Exam (125) and time allotment (150 minutes). My school was not clear on the passing grade required for their institution, but I believe it was over a 75%. Hope this helps, feel free to send me a message with more specific questions or if you'd like a copy of the study guide that I made from my book (it's question/answer format, good for quizzing). Good luck!
