I just finished my first year at Truman College here in Chicago, and as such just took the mid-curricular Hesi exam. A few words about the Hesi that we weren't told that others after me will find useful:
*The exam was 110 questions.
*I got anywhere from 20 to 25 wrong (you're allowed to look over your wrong answers and rationales at the end of the test, and I forgot to count as I went through them) and still got a 92% and a 1043, or something like that (800 was required). This leads me to believe that some questions are weighted more than others, but I can't confirm that conclusively.
*There will be questions on the exam that you didn't cover in class (Cancer, meds you never studied). Don't worry too much about these - you will likely be able to pick out the correct answer if you have ANY skill at all in answering NCLEX - style questions.
*I spent a lot of time studying procedures - how to take a sitting, then standing BP, taking a BP in both arms, donning/doffing PPE - and there were maybe 2 or 3 questions on this.
*A lot of the test was just nursing judgment - general nursing questions about what to do first. Believe me, if you've finished two semesters of Nursing school and passed, you know more about this than you think.
*If you get stumped by strange terms - ecchymosis, petechiae have always thrown me - study them. There will be questions where if you don't know what the word means, you won't be able to answer the question.
*Finally, everyone I talked to passed. I'm sure a few of the 130 or so of us failed had to go to summer school, but keep in mind that you'll have just take a comprehensive final, and that will prepare you very well for this exam.
Wish I knew this before going into the test - would have put me at ease!!
