90% of the test is scenarios to make sure that the care you provide to patients would be proper and not innefective or causing further damage to your patient. Go back through your book and run through possible scenarios.
ex. You come up on a 32 yr old female patient who is having contractions 1 minute apart. She feels like she needs to use the restroom. What do you do?
Ok, so you didn't let her use the restroom, you calmed her down as best you could, you laid her down and checked for crowning. She is not crowning. Now what?
Run through these kind of scenarios and make sure you have these down. If you get patient care down, you should do just fine.
