What I can tell about taking nursing tests is there are usually 2 right answers but one is the 'best.' When I took fundamentals they didn't cover ADPIE all in one test, as we learned them throughout the semester. You must know what is done during each part of the process and if you've prepared well, u should do fine. Read the stem of the question, ask yourself what the question is asking and begin the process of elimination. 2 should be wrong right away and then decide which one is the best. Go with your first instinct and do not change it! Avoid reading into the question, just answer what it is asking. There should be test questions that ask about priority, initial, first, etc., these are cues.
Hope this helps and good luck!
