Just took CCRN and passed. I was surprised at how simple the questions were. As others are saying I overstudied. No complex scenarios.It felt more like a new nurse exam. Questions on dilantin dosing, how to confirm NGT placement, 2 questions on dementia..really? I studied from PASS CCRN questions. Those were way more challenging. There were no "signs" except Cullen's. I overstudied obscure signs. DI/ SIADH pretty basic- which way electrolytes go. Pure memorization. No physiology questions, nothing on renal function tests. Dont waste time on any 12 lead interpretation except for the basic leads associated with inf, septal, anterior... Forget about BBB, axis deviation.Did need to know cranial nerves. Nothing complex. I think taking an overview course would suffice for this test. The textbooks are just too complex. Tips- know which way CO, PA, RA, PCWP go with heart failure, hypovolemic shock, MI. Know what drugs to give for these also. For nursing ethics, pick the "nice" answer. I studied Maslow and stages of dying- not on there. One ekg- a flutter , had to pick drugs for that. Don't waste time knowing anything too indepth- for example anatomy of organs and how they work at cellular level. Know electrolytes, how they behave hi and low, and intra/extracellular fluid. Know about blood transfusion triggers, therapeutic hypothermia, pancreatitis signs on a simple level. All in all, the test felt dated and somewhat poorly written. What the test did do, is force me to relearn basic medicine again. For that I am happy.
