Uggggh. I hate NS questions.
Sometimes you read into the question too much....according to your instructor.
Sometimes, the question seems simple but you didn't read into it (or critically think) enough......according to your instructor.
Sometimes, it really is simple but you are reading into it too much....
Plus, factor in questions that ARE poorly worded cuz let's face it...we are only human....even the writers of the NCLEX questions...
Trick is....pray to God you actually learn something in NS, answer the stupid questions, and walk out happy with a 76% and DON'T THINK ABOUT THE QUESTIONS AGAIN. IT WILL DRIVE YOU ABSOLUTELY BATTY!!! In test review, if you answered one way and the instructor says it is wrong for X reason (but you still have a very strong argument that you are right) just smile and say "OK". That is when he will probably say, "Well, you are right, but so is this".
You just can't win em all. Just 76% of them.

(or whatever)
