Hi! I had to take this test as well when I started on an SICU as a new grad! I think the norm was for people to fail. In fact, I think the educator said that only 2 or 3 people that she knew of had passed on their first attempt. And we weren't all new grads. It was a mix of new grads and some nurses with a few years of experience. The main purpose of the test is a knowledge assessment, right? We took the exam and all had to go to new-hire critical care classes regardless of whether we passed or failed. At the end of the classes, the people who failed the first time had to retake the exam. No big deal. Review what you missed so you know what to work on, and pass the exam the next time you take it!
PS- I always have a hard time on "priority" questions because I think of how it happens in real life- all at once. I just always have to remember the hierarchy of needs, and break it down further starting with Airway, Breathing, and Circulation. That usually helps!
