Testing and mind reading abilities

Do you ever feel like you are required to crawl into your instructor's mind and read it during a test? I've done really well on my first few tests in fundamentals and pulled an A on both but I am amazed at some of the questions and how they sort of seem to expect us to be able to draw nearly impossible conclusions. So far, I've been lucky and guessed right but many haven't.

An example: On our last test we were asked a question regarding legalities. The situation was that a nurse had wrote down that a client was using street drugs. The family later found this information and we were supposed to know if the nurse was guilty of libel, slander, negligence or some fourth factor I can't remember but was ridiculous and obviously not the answer. Pretty easy stuff except many students were left with the thought process that this was something the nurse had documented or charted and that would point to negligence if she left it in plain view of family members. The answer was libel, and it was what I chose, but many missed it it. One student asked the instructor about it and was told that since the RN just "wrote it down on a piece of scratch paper" that it wasn't something charted and therefore not negligent but libelous. But the question didn't specify charted or not, just that it had been written down.

I was left wondering to myself how we are supposed to pick out these details that the instructors have in their

head but aren't provided to us. How do you deal with the missing blanks?
