I was so nervous for this test, but it wasn't bad at all! I passed with an "A". It took me a little over an hour to take the test (including going through each question twice).
Most of the questions seemed like basic common sense. There were 3 or 4 that I was really stumped on, so I just tried to pick the answer that seemed most of out place of the four choices.
For this test, I'd suggest understanding the nursing process inside and out and backwards. It's not enough to just know "AIDET". You have to understand what each step entails. Also, understanding the therapeutic nursing approaches would be good.
I think if you take your time and read the chapters for this test you will be ok. I honestly found the Transitions test to be a lot harder, but then again I didn't really study for it and got a "C". I also used the SG101 notes. The practice tests helped a lot for Health Safety.
I did take both practice exams through EC for Health Safety, and surprisingly couldn't get more than a 65% on either of them, so I was nervous for the rest thing. But it turned out to be a breeze.
I'm moving onto Health Differences next.
